Description
The CHV-THSTAT is a versatile heating and cooling thermostat with integrated humidistat designed for one- and two-stage control of forced air, radiant, and heat pump HVAC systems. Although functional as a standalone thermostat, the CHV-THSTAT delivers greatly enhanced functionality as part of a complete automation system from Crestron Available in white, black, or almond, the stylish wall mount design is a complement to any decor.

Connectors- HVAC (2) 9-position terminal blocks comprising the following:
- Power Connections (Required):
- 24 (C): 24 VAC common terminal supplies remote 24 VAC power to thermostat;
- 24 (R): 24 VAC reference terminal – Can be Connected to RH or RC by P4 jumper setting, or tied directly to power source
- HVAC Control Connections (System Dependent):
- HUM: Energized to RHU during humidity call;
- RHU: Reference for humidifier;
- RH: Reference Heat – Used for calls to heating system;
- RC: Reference Cool – Used for calls to cooling system;
- G: Fan – Energized to RC during call for fan;
- Y/Y1: Compressor (stage one) – Energized to RC when compressor (or first stage) is run;
- Y2: Compressor (stage two) – Energized to RC on two-stage systems on call for second stage;
- O: Changeover control – Energized to RC during cooling modes;
- B: Energized to RC during non-cooling modes;
- W/W1: Heat (single stage)/heat (stage one) – Energized to RH during a call for heat in heat/cool systems or aux heat in heat pump systems;
- W2: Heat (stage two) – Energized to RH during a call for second stage heat in heat/cool systems
- Remote Sensing Connections (Optional):
- RSR: Remote Sensor Returns – Common sensor terminal;
