INSTALLATION

When Installing this Product…

1. Read these instructions carefully. Failure to follow

the instructions can damage the product or cause a

hazardous condition.

2. Check the ratings given in the instructions and on the

product to make sure the product is suitable for your

application.

3. Installer must be a trained, experienced service

technician.

4. After completing installation, use these instructions to

check out the product operation.

Location

Do not install the thermostat where it can be affected by:

—drafts, or dead spots behind doors and in corners.

—hot or cold air from ducts.

—radiant heat from sun or appliances.

—concealed pipes and chimneys.

—unheated (uncooled) areas such as an outside wall behind

the thermostat.

T7200 Wallplate or Q7300 Subbase without

Remote-Mounted Temperature Sensor

Install the thermostat about 5 ft (1.5m) above the floor in

an area with good air circulation at average temperature.

See Fig. 2.

Q7300 Subbase with Remote-Mounted

Temperature Sensor(s)

If only the remote-mounted temperature sensor(s) is used

to sense and control room temperature, then install the

thermostat in an area that is accessible for setting and

adjusting the temperature and settings.

If both the subbase and remote-mounted temperature

sensor(s) are used to sense and control room temperature,

then install the subbase about 5 ft above the floor in an area

with good air circulation.

Install the remote-mounted sensor(s) about 5 ft (1.5m) above

the floor in an area with good air circulation at average

temperature. See Fig. 2.

If multiple remote sensors are required, they must be

arranged in a temperature averaging network consisting of

two, three, four, five or nine sensors. See Fig. 3 through 8.

NOTES:

—When sensor averaging, the T7147A can be substituted

for the T7047C. The T7147A includes OVERRIDE and

WARMER/COOLER keys.

—Up to four T7147As can be used in parallel to place the

thermostat in Temporary Occupied.

Fig. 2. Typical location of thermostat

or remote-mounted sensor.

IMPORTANT

To avoid electrical interference, which can cause

erratic performances, keep wiring runs as short as

possible and do not run thermostat wires adjacent to

the line voltage electrical distribution systems. Use

shielded cable (Belden type 8762 or equivalent for

2-wire and Belden type 8772 or equivalent for

3-wire). The cable shield must be grounded only at

the controlled equipment case.

temperature.

Mounting Subbase/Wallplate

The subbase/wallplate mounts horizontally on the wall or

a 2 in. by 4 in. wiring box. Position the subbase/wallplate

horizontally on the wall or on a 2 in. by 4 in. wiring box.

1. Position and level the subbase/wallplate.

NOTE: A level wallplate is only for appearance. The

thermostat functions properly when not level.

2. Use a pencil to mark the mounting holes. See Fig. 9.

3. Remove the subbase/wallplate from the wall and drill

two 3/16 inch holes in the wall (if drywall) as marked.

For firmer material such as plaster or wood, drill two

7/32 inch holes. Gently tap anchors (provided) into the

drilled holes until flush with the wall.

4. Position the subbase/wallplate over the holes, pulling

wires through the wiring opening.

5. Loosely insert the mounting screws into the holes.

OPERATION

T7200/T7300 Relay Logic

The T7200/T7300 contains three switching relays. In

conventional applications, the relays control first stage

cooling, first stage heating, and fan. In heat pump

applications, the relays control the heat pump compressor,

auxiliary heat, and the fan. Because of this change in

switching logic, it is important to use a Q7300C,D,

Q7300H2003, or Q7300H2011 Subbase when the T7300 is

set for heat pump applications and a Q7300A,G,

Q7300H2029 Subbase when the T7300 is set for

conventional applications.

The T7200D Relay Logic is for conventional applications.

The T7200E Relay Logic is for heat pump applications.

T7200/T7300 and Conventional Thermostats

P+I Control

The T7200/T7300 microprocessor based control requires that

the user understands temperature control and thermostat

performance. A conventional electromechanical or electronic

thermostat does not control temperature precisely at setpoint.

Typically, there is an offset (droop) in the control point as the

system load changes. This is a phenomenon that most people

in the industry know and accept. Many factors contribute to

offset including switch differential, thermal lag, overshoot,

cycle rates and system load.

The thermostat microprocessor simultaneously gathers,

compares and computes data. Using this data, it controls a

wide variety of functions. The special proprietary algorithm

(program) in the thermostat eliminates the factors causing

offset. This makes temperature control more accurate than

the conventional electromechanical or electronic thermostats.

The temperature control algorithm is called proportional plus

integral (P+I) control.

The thermostat sensor, located on the thermostat or remote,

senses the current space temperature. The proportional error

is calculated by comparing the sensed temperature to the

programmed setpoint. The deviation from the setpoint is the

proportional error.

The thermostat also determines integral error, which is a

deviation based on the length of error time. The sum of the

two errors is the (P+I) error. The cycle rate used to reach and

maintain the setpoint temperature is computed using the P+I.

The addition of the integral error is what differentiates the

thermostat from many other electronic and electromechanical

thermostats. See Fig. 18.

Fig. 18. Proportional temperature control

versus P+I temperature control.

Equipment Protection

As part of the operational sequence, the T7200/T7300

microprocessor also incorporates minimum on and off times

for all heating and cooling stages. Minimum on time is set in

the installer setup number 32. Using the minimum on and off

times assures that rapid cycling of equipment does not occur,

which extends equipment life. Minimum on and off times are

set in the Installer Setup.

T7200/T7300 Thermostat Operation

Startup

When power to the thermostat is turned on, a startup and

initialization program begins. The startup occurs only on initial

powerup. After total loss of power for an extended period, the

current time and day may need to be set, but the user

program is held. The initial default values are heating 68°F

(20°C) and cooling 78°F (26°C) for the Occupied periods.

Unoccupied default values are heating 55°F (13°C) and

cooling 90°F (32°C).

NOTE: The thermostat controls to the Unoccupied default

setpoints of 55°F (13°C) for heat and 90°F (32°C) for

cool when no program is set.

Occupied Operation

When the thermostat is operating in the Occupied period,

the temperature is controlled to the occupied heat or cool

setpoint. The normally open (A1) auxiliary relay contacts are

closed and the normally closed (A3) auxiliary relay contacts

are opened during the Occupied periods (if the subbase being

used has this option). The fan operates as follows: fan

selection can be set to On (always energized) or Auto (cycles

with Y1 or W1).

Unoccupied Operation

When the thermostat is operating in the Unoccupied period,

the temperature is controlled to the Unoccupied heat or cool

setpoint. The normally open (A1) relay contact is open and the

normally closed (A3) relay contact is closed. The fan operates

as follows: fan is always intermittent (cycles with Y1 or W1).

Intelligent Recovery® Feature

Intelligent Recovery is a Honeywell trademarked feature

for the way the thermostat controls heating and cooling

equipment during recovery from the Unoccupied to Occupied

setting. During recovery, the control point changes gradually

rather than shifting immediately from the energy saving

setting to the comfort setting.

When Intelligent Recovery is used in heating, the control point

raises gradually, maximizing the use of the more economical

first stage heat to bring the sensed temperature to the desired

comfort setpoint. This minimizes using the typically more

expensive second-stage heat.

Advantages of Intelligent Recovery are:

•Comfort setting is achieved at the programmed time and

maintained regardless of weather conditions; occupants

are comfortable.

•Drafts from low-temperature discharge air are minimized

during Occupied periods.

•The more economical first stage of heat is the primary heat

source during recovery, minimizing use of the expensive

second-stage heat.

•Comfort and energy savings can be achieved in both

heating and cooling.

•Heat cycling reduced, extending equipment life.

RECOVERY FROM UNOCCUPIED

The heat pump heat recovery ramp is 3°F (1.6°C) per hour.

This differs from the 5°F (2.8°C) per hour for conventional

systems. The 3°F helps the system use the economical heat

pump more and the expensive auxiliary heat less. The cooling

ramp is 5°F, the same as for conventional systems.

Conventional System

The T7200 and T7300D,F Thermostats with Q7300A,G,H

Subbases are designed for conventional heat/cool

applications.

Heat Pump Operation

The T7200E and T7300E,F Thermostats with Q7300C,D,H

Subbases are designed for heat pump applications. Additional

information is required when configured for heat pump

applications.

O AND B TERMINALS FOR HEATING OR COOLING CHANGEOVER

The Q7300C controls heat pump changeover. The Q7300D,H

is only used in a heat pump application when the heat pump

controls the reversing valve changeover. See Table 12 for the

operation of the O and B terminals on the Q7300C, H2003.

O AND B TERMINALS ON A CONVENTIONAL SUBBASE

Conventional subbase O and B terminals can be used to drive

dampers and valves. The O terminal is energized on a call for

cool and the B terminal is energized on a call for heat.

Table 12. Operation of Q7300 O and B terminals.

aWhen the system is calling for heat or is de-energized, but

the last function was heat.

bWhen the system is calling for cool or is de-energized, but

the last function was cool.

cWhen the last function was heating, the operation is the

same as Auto (Heat). If the last function was cooling, the

operation is the same as Auto (Cool).

FAN OPERATION

When the fan is set to On, the fan is energized continuously in

the Occupied period. The Auto setting energizes the fan with

the heating or cooling system. If the subbase is Q7300D, the

fan cycles with Y1 and W1 during Unoccupied period.

EMERGENCY HEAT (SELECT T7300 THERMOSTATS ONLY)

With the system set for Em Heat, auxiliary heat serves as

stage one; compressor stages are locked off. The fan cycles

with the auxiliary heat.

COMMUNICATING SUBBASE

Select T7300F Thermostats with the Q7300H Communicating

Subbase are designed for conventional or heat pump

applications in a LonWorks® network. The Q7300H Subbase

allows remote access and the sharing of clock, schedule,

setpoints, bypass and other system parameters in a

LONWORKS® network. See Fig. 33 for a T7300F/Q7300H

wiring layout in a LONWORKS® network.

GENERAL OPERATION INFORMATION

Cycle Rates

The thermostat control algorithm maintains the temperature

by cycling stages of heating or cooling to meet setpoint.

Subbase Auxiliary Relay

The Q7300 Auxiliary Relay output acts as a time-of-day switch

to be used with an economizer minimum position control. The

normally open (A1) auxiliary relay contacts are closed during

the Occupied period and open during the Unoccupied period.

The normally closed (A3) auxiliary relay contacts are open

during the Occupied period and closed during the Unoccupied

period. The contacts are in the normal state during recovery.

Interfacing with Electromechanical

Economizers (Subbases with Auxiliary Relay)

Mechanical cooling is often used when outside temperatures

are in the 50°F (10°C) to 60°F (16°C) range and humidity is

below 50 percent. In central and northern climates, hundreds

of hours fall into this temperature category. By permitting 80 to

100 percent outside air into the system, mechanical cooling

may not be needed at all, particularly during Spring and Fall.

An economizer is used to take advantage of the outside air.

The typical economizer consists of an outside air damper,

motor, outdoor air changeover control and a minimum position

potentiometer. The motor controls the dampers. Suitability of

the outside air for cooling is determined by the outdoor air

changeover control. The potentiometer is used for adjusting

the minimum position of the economizer dampers, which

provide a minimum amount of fresh air for ventilation.

The economizer reduces compressor run time, thereby saving

energy and extending the compressor life. The drawback to

using the economizer is that during the Unoccupied period, if

there is no call for cool or outdoor air is not suitable for free

cooling, the economizer is controlled to minimum position.

This position allows some percentage of outdoor air to enter

the building, regardless of air suitability. The situation can

cause the heating or cooling to run more often than if suitable

outdoor air is permitted to enter the building.

The thermostat can take advantage of an economizer by

connecting the subbase auxiliary relay contacts (A1 and A2)

to control the economizer minimum position potentiometer.

The contacts close during the Occupied period, allowing the

economizer to operate normally. The contacts open during the

Unoccupied period, disabling the minimum position feature of

the economizer. The open contacts cause the economizer to

drive dampers fully closed instead of staying at minimum open

position. This reduces the possibility of unsuitable outdoor air

from entering the building, which lowers the internal load on

the HVAC system and saves additional energy.

Other Uses for the Auxiliary Relay

Examples of other uses of the auxiliary relay are hot water

heaters, lighting or baseboard heat. The additional loads are

connected to the auxiliary relay contacts on the subbase. The

contacts are rated for 1.6A at 30 Vac, but can be adapted to

higher current applications with the use of an external relay

and transformer. See Fig. 19.

CROSS REFERENCE

All T7300/Q7300 Series 2000 models are different from the existing T7300/Q7300 T8611 and T8621 devices as summarized in

Table 14.

Temperature settings

change from original

setting.

Trying to set heat and cooling setpoints

too close together. Automatic changeover

thermostat models have a deadband.

Example: cool setpoint: 72, deadband: 3,

heat setpoint: 68; changing heat setpoint

to 70 automatically changes cool setpoint

to 73.

•Check that the heating setpoint is lower than the

cooling setpoint.

•Check Installer Setup number 30 to identify the

deadband between heating and cooling setpoints.

Reconfigure if desired.

Room temperature is out

of control. Remote temperature sensing is not

working. Checkout all remote sensors.

Heating will not come on. No power to the thermostat. •Check that X terminal is connected to the system

transformer.

•Check for 24 Vac between X and R or RH terminals.

—If missing 24 Vac:

—check if the circuit breaker is tripped; if so, reset

the circuit breaker.

—check if the system fuse is blown; if so, replace

the fuse.

—check if the HVAC equipment power switch on

the is in the Off position; if so, set to the On

position.

—check wiring between thermostat and HVAC

equipment and replace any broken wires and

tighten any loose connections.

—If 24 Vac is present, proceed with troubleshooting.

Heating will not come on

(Continued). Thermostat minimum off time is activated

and wait indicator is displayed. •Wait up to five minutes for the system to respond.

•Enter Installer Setup number 38. Reconfigure

minimum off time (if required).

System selection is not set to Heat. Set system selection to Heat.

Cooling will not come on. No power to the thermostat. •Check that X terminal is connected to the system

transformer.

•Check for 24 Vac between X and R or RC terminals.

—If missing 24 Vac:

—check if the circuit breaker is tripped; if so, reset

the circuit breaker.

—check if the system fuse is blown; if so, replace

the fuse.

—check if the HVAC equipment power switch on

the is in the Off position; if so, set to the On

position.

—check wiring between thermostat and HVAC

equipment and replace any broken wires and

tighten any loose connections.

—If 24 Vac is present, proceed with troubleshooting.

Thermostat minimum off time is activated

and wait indicator is displayed. •Wait up to five minutes for the system to respond.

•Enter Installer Setup number 33. Reconfigure

minimum off- time (if required).

System selection is not set to Cool. Set system selection to Cool.

System on indicator

(flame: heat,

snowflake: cool) is

displayed, but no warm

or cool air is coming from

the registers.

Conventional heating equipment turns on

the fan only once the furnace has warmed

up to a setpoint.

Wait one minute after seeing the on indicator and then

check the registers.

Heating or cooling equipment is not

operating. Verify operation of heating or cooling equipment in self-

test.
