No. Relay Description Details
1 Digital Compressor Confi gured for a Digital Compressor.
2 Cooling Stage Confi gured for each fi xed stage of cooling (except heat pump compressor).
3 Heating Stage Confi gured for each fi xed stage of heating.
4-5
Condenser #1
Condenser #2 Confi gured for Condenser Fan/Valve operation. This relay(s) will be active anytime the respective
compressors are active, except if the unit is in Heat Pump Defrost Mode.
6 Heat Pump Water Valve On a Water Source Heat Pump, this relay will be active anytime compressors are active.
7 Heat Pump Compressor Confi gured for a Fixed Heat Pump Compressor stage.
8 Reversing Valve Confi gured for the Reversing Valve of a heat pump unit.
9 Aux Heat Confi gured for a fi xed stage of Aux Heat in a heat pump unit.
10 Emergency Heat Confi gured for a fi xed stage Emergency Heat in a heat pump unit.
11 Mod Heat Enable Confi gure if a 0-10 VDC Modulating Heat source needs a relay to enable it.
12 Mod Cool Enable Confi gure if a 0-10 VDC Modulating Cool source needs a relay to enable it.
13
Morning Warm-Up/
Cool-Down (VAV Boxes) Confi gure (1) Relay for Morning Warm-Up/Cool-Down when Non-Orion VAV/Zone Controllers are
used.
14 Reheat Confi gure (1) Relay for On/Off Reheat when used.
15 Pre-Heat Confi gure for Pre-Heat operation.
16 Low Ambient Confi gure for Low Ambient operation.
17 Exhaust Fan Confi gure (1) Relay for enabling exhaust fan when Building Pressure Control is used.
18
Economizer Active If confi gured, this relay will energize if unit is in Economizer mode and the damper has moved 5%
above its Economizer Minimum Setpoint position.
19 Heat Wheel
Confi gure (1) Relay that turns heat wheel on when in Occupied operation and turns heat wheel off
when in Economizer Mode.
20 Occupied Active If confi gured, this relay will energize whenever the unit is in the Occupied Mode.
21 Override Active If confi gured, this relay will energize anytime the space sensor Push-button override is active.
