T4039 Thermostats Control Line Voltage Valves of

a fan coil unit in cooling, manual changeover heat-

ing-cooling, or automatic changeover heating-cool-

ing systems. One or two valves may be controlled

directly by the thermostat. The fan switch (where

applicable) controls air circulation.

■Color-coded leadwires.

■All models can be mounted on standard vertical

outlet boxes. Models with manual switching can be

mounted on 4 in. square junction boxes or 2-

ganged outlet boxes.

■Adjustable range stops limit temperature adjust-

ment or lock at selected setpoint.

■Models available with separate power source for

fan and thermostat.

■1-, 2-, or 3-speed manual fan control available.

■Positive deadspot separates heating-cooling circuits

in automatic models. Remote changeover switch is

required to separate circuits in manual changeover

heating-cooling models.

■Scale range is approximately 55° F to 95° F [13° to

35° C] in 10° F [6° C] increments from 75° F [24°

C] midpoint. Scale is marked COOL-WARM.

■Cooling circuit breaks in FAN-OFF position to re-

duce condensation problems in the fan coil unit.

2. Open the cardboard inside cover by pressing inward on

the left side to release latch. Do not remove this cover.

3. Carefully remove the shipping inserts from around the

snap contacts.

4. Check contact operation before mounting device.

MOUNTING

Models without manual switching mount on standard

vertical outlet boxes. Models with manual switching

mount on 4-in. square junction boxes or 2-ganged outlet

boxes. Manual switching models can also mount on stan-

dard vertical outlet boxes if local electrical codes permit.

Mount thermostat on side wall about 5 ft. [1.5 m] above

the floor. Do not mount where thermostat can be affected by

drafts, radiant heat from the sun or other sources of heat.

Use Allen wrench to open cover and mount according

to Fig. 3. Two mounting screws are provided.

WIRING

Disconnect power supply before beginning installa-

tion to avoid electrical shock or equipment damage. All

wiring must comply with local codes and ordinances.

Internal schematic and external connections for the

T4039 are shown in Fig. 4. Use solderless connectors or

other approved methods to wire thermostat into the sys-

tem. Six-inch color-coded leadwires are provided.

SETTING

The T4039 temperature scale is marked COOL-WARM

with approximate scale divisions of 10° F from 75° F

[24° C] midpoint. The range is approximately 55° F to 95°

F [13° C to 35° C]. Set lever at desired temperature.

To adjust the temperature setpoint range stops, Fig. 3,

locate stops at the desired temperature range setpoint

and insert.

Operation

In heating applications, as the temperature drops, the

thermostat heating contacts make to open a valve that

allows hot water to flow through the coil. On select models,

the speed at which the heat is circulated is controlled

manually by the fan switch.

In cooling applications, as the temperature rises, the

thermostat cooling contacts close to open a valve that

allows cold water to flow through the coil. Cooling mecha-

nism will not operate if manual switch is in the OFF

position. Models T4039D,H,K,M,S,V will also turn off

the heating valve when the manual switch is in OFF.

In manual changeover heating-cooling models, the

thermostat must be used with a remote changeover switch

or control to select the proper heating or cooling cycle

for the thermostat.

CALIBRATION

The T4039 is accurately calibrated at the factory under

controlled conditions. Do not attempt to field calibrate

this device.

Check the T4039 before leaving the installation. Raise

the temperature setting to start the heating cycle or lower the setting to start the cooling cycle. Check both cycles

on heating-cooling models.
