VCM & VCM-X Relays Setpoints
Relays Setpoints
Touch the < Relays> button to access the Outputs Setpoints
Screens. Touch the radio button next to the desired relay se-
lection. Choose one relay output from each screen for Relays
2 through 21. Relays #2 through #21 can be individually
confi gured. By using the available relay outputs on the Controller and
Expansion Modules, you have the ability to confi gure up to a combined
total of 20 Heating Stages, Cooling Stages, and the rest of the options listed
in each Outputs Setpoints Screen. Only the Heating and Cooling relays
can be confi gured with multiple outputs. If any other option is selected
more than once, it will simply activate redundant relays, but no multiple
staging will occur. See Table 6 for Relay Defi nitions.
.
NOTE: Relay #1 is not confi gurable as it is reserved for the
Supply Air Fan.

No. Relay Description Details
1 Heating Stages Confi gure (1) Relay for each stage of heat. Confi gure (1) Relay for Mod heat.
2 Cooling Stages Confi gure (1) Relay for each stage of cooling. For chilled water, confi gure (1) Relay for cooling.
3 Warm-Up Mode (VAV Boxes) Confi gure (1) Relay for Warm-Up Mode when Non-Orion VAV/Zone Controllers are used.
4 Reversing Valve (Heat Pumps) Confi gure (1) Relay for Reversing Valve operation. Can be confi gured for heating or cooling.
5 Reheat Confi gure (1) Relay for On/Off reheat when used.
6 Exhaust Fan Confi gure (1) Relay for enabling exhaust fan when building pressure control is used.
7
Pre-Heater
(low ambient protection) Confi gure (1) Relay for pre-heat coil when required. Activated when the outdoor air temperature
drops below the ambient protection setpoint.
8 Alarm Confi gure (1) Relay to initiate an alarm output when any VCM-X alarm occurs.
9 Override Confi gure (1) Relay to initiate an output signal when space temperature override button is pushed.
10 Occupied Confi gure (1) Relay to initiate an output signal any time the VCM-X is in occupied mode.
11 OA Damper
Confi gure (1) Relay to initiate an output signal when the OA damper moves beyond its minimum
during economizer operation, when the OA damper opens, when Hood On/Off is used, when Hood
Contact is used, and with MUA applications.
12 Heat Wheel
Confi gure (1) Relay that turns heat wheel on when in occupied operation and turns heat wheel off
when in economizer mode.
13 Emergency Heat
Confi gure (1) Relay for fi xed stage Emergency Heat in a heat pump unit. Not available on VCM-X
WSHP E-BUS controller.
