Connectors
HVAC
(2) 9-position terminal blocks comprising the following: Power Connections (Required):
24 (C): 24V AC common terminal supplies remote 24V AC power to thermostat;
24 (R): 24V AC 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;
RS1: Remote Sensor terminal – Connect the sensor from RS1 to RSR;
RS2: Remote Sensor terminal – Connect the sensor from RS2 to RSR
 
NETWORK
(1) 4-position terminal block;
Cresnet slave port, connects to Cresnet control network
