Thermostats
T4039 Thermostat
T4039 thermostats control the line-voltage valves of fan coil units in cooling, manual changeover heating-cooling, or automatic changeover heating-cooling systems.
Overview
T4039 thermostats control the line voltage valves of fan coil units 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.
Features & Benefits:- Manual fan control available
- Positive dead spot separates heating-cooling circuits in automatic models
- Scale range is approximately 55 to 95 °F (13 to 35 °C) in 10 °F (6 °C) increments from 75 °F (24 °C) midpoint
- Cooling circuit breaks in "FAN-OFF" position to reduce condensation problems in the fan coil unit
- Color-coded lead wires
- All models can be mounted on standard vertical outlet boxes. Models with manual switching can be mounted on 4-inch square junction boxes or 2-gang outlet boxes
- Adjustable range stops limit temperature adjustment or lock at selected setpoint
- Models available with separate power source for fan and thermostat
