APPLICATION

The T8611G Chmnothern'_ IV Deluxe Programmable Heat Pump Thermostats provide electronic control of 24 Vac

alngid*zone heat pump systems. Refer to Table 1for a general description of the thermostats. All T8611 thermostats

require a common wire to supply power,

INSTALLATION

When Installingthis Product...

1, Read these instructionscarefully. 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 outthe product operation.

Location

Install the thermostat about 5 II (t .Sin) above the floor in

an area with good air circulation at average temperature,

See Fig. 1,

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

-- drafts, or dead sppts behind doors and incornere.

-- hot or cold air from ducts.

-- radiant heat from sun or appliances,

mconcealed pipes and chimneys.

-- unheatad (unccoled) areas such as an outaide wall

behind the thermostat.

WallplateInstallation

The thermostat can be mounted horizontally on the wall

or on a 2 in. x 4 in.wiring box. Position wallptste

hodzordally on the wail or on a 2 in, x 4 in. widng box.

1. Position and level the waitplate (for appearan¢_

only). The thermostat will func_on properly even

when not level.

2. Use a ppnciJ to mark the mounting hoJes.See

Fig. 2.

3. Remove the wallptata from the wall and ddfl two

3/16 inch holes inthe wall (if drywall) as marked.

For firmer material such as plaster, ddll two 7/32

inch holes. Gently tap anchors (provided) into the

drilled holes until flushwith the wall.

4. Position the wallplate over the holes, pulling wires

through the wiring opening.

6. Loosely insert the mounting screws into the holes.

6. Tighten mounting screws.

WIRING

All wiring must comply with local electrical codes and

ordinances. Refer to Fig. 3 for typlcst hookup. A letter

code is located near each terminal for identification.

CAUTION

Disconnect power before wiring to prevent

electrical shock or equipment damage.

1. Loosen the terminal screws on the wallplate and

connect the system wires, See Fig. 4.

SETrlNGS

Systemand FenSettings

The system defeult setting is Heat and the fan default

setting is Auto. Use the System and Fan keys to change

the settings, See Fig, 7. The fan settings can be set for

each program period individually.The system selection is

for all the program periods.

System settings control the thermostat operation as

follows:

Em Heat: Emergency heat relay Is on conttnuousty.

Thermostat cycles highest stage of heat. Cooling

system is off.Compressor is de*energized.

Heat: The thermostat controls the beating.

Off: Both the heating and cooling are off.

Cool:The thermostat controls the cooling.

Auto:The thermostat automatically changes between

heating and cooling operation, depending on the

indoortomporature.

Fan settings control the system fan as follows:

On: Fan operates continuously.

Auto: Fan operates with equipment.

LED Indication

Two LED indicators are located in the upper right of the

thermostat.They indicate when a CHECK or FAIL signal

is sent to the thermostat from the system. See Fig. 3.
