T4039A,B,D-M,S,V Line Voltage Cooling and Heating-Cooling Thermostats T4039 Thermostats Control Line Voltage Valves of a fan coil unit in cooling, manual changeover heating-cooling, or automatic changeover heating-cooling systems. One or two valves may be controlled directly by the thermostat. The fan switch (where applicable) controls air circulation. ■ 1-, 2-, or 3-speed manual fan control available. ■ Color-coded leadwires. ■ Positive deadspot separates heating-cooling circuits in automatic models. Remote changeover switch is required to separate circuits in manual changeover heating-cooling models. ■ All models can be mounted on standard vertical outlet boxes. Models with manual switching can be mounted on 4 in. square junction boxes or 2ganged outlet boxes. ■ 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. ■ Adjustable range stops limit temperature adjustment or lock at selected setpoint. ■ Cooling circuit breaks in FAN-OFF position to reduce condensation problems in the fan coil unit. ■ Models available with separate power source for fan and thermostat.

Models with manual switching mount on 4-in. square junction boxes or 2-ganged outlet boxes. Manual switching models can also mount on standard 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. WHEN INSTALLING THIS PRODUCT… 1. Read these instructions carefully. Failure to follow them could 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 the installation is complete, check out product operation as provided in these instructions. WIRING Disconnect power supply before beginning installation 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 system. Six-inch color-coded leadwires are provided. CAUTION Disconnect power supply to prevent electrical shock or equipment damage. Before mounting, be sure to remove cardboard shipping inserts that protect the contacts. 1. Remove T4039 cover by loosening the cover screw with Allen wrench. 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. 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. 5 60-2241—8 T4039A,B,D-M,S,V INSTALLATION Fig. 4—Internal schmeatics and external connections for T4039 Thermostats.

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 mechanism 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. Checkout Check the T4039 before leaving the installation. Raise the temperature setting to start the heating cycle or lower Home and Building Control Honeywell International, Inc. 1985 Douglas Drive North Golden Valley, MN 55422 the setting to start the cooling cycle.
