LineVoltage Cooling and

Heating-CoolingThermostats

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.

■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 reduce condensation problems in the fan coil unit.

■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 adjustment or lock at selected setpoint.

■Models available with separate power source for fan and thermostat.
