ERV Operation: When in Cooling mode AND the conditions are NOT OK for economizing - the ERV terminal will be energized.
In the Heating mode the ERV terminal will be energized when the OA is below the ERV OAT setpoint in the setpoint menu.

Temp to activate Freeze Protection (close damper and alarm if
temp falls below setup value)
Damper position when freeze protection is active (closed or MIN
POS).
CO2 ppm level to match CO2 sensor start level.
CO2 ppm span to match CO2 sensor.
Delay after stage 2 for cool has been active. Turns on 2nd stage of
cooling when economizer is 1st stage and mechanical cooling is
2nd stage. Allows three stages of cooling, 1 economizer and 2
mechanical.
OFF = no Stage 3 cooling.
Delay between stages 1 and 2 for cool
Indicates shutdown signal from space thermostat or unitary
controller. When controller receives 24 Vac input on the SD
terminal in conventional mode, the OA damper will open if
programmed for OPN and OA damper will close if programmed for
CLO. All other controls, e.g., fans, etc. will shut off.
Turns on the DCV automatic control of the dampers. Resets
ventilation based on the RA, OA and MA sensor conditions. See
Product Data sheet 63-2700 for details. Requires all 3 RA, OA and
MA sensors.
Positions damper to VMIN position
Positions damper to VMAX position
Positions damper to the full open position.
Exhaust fan contacts enable during the DAMPER OPEN test. Make
sure you pause in this mode to allow for exhaust contacts to
energize due to the delay in the system.
Positions damper to the fully closed position
Closes the Y1-O relay (Y1-O)
Closes the Y2-O relay (Y2-O)
Energizes the AUX output. If Aux setting is:
• NONE – no action taken
• ERV – 24 Vac out. Turns on or signals an ERV that the
conditions are not good for economizing but are good for ERV
d
operation.
• SYS – 24 Vac out. Issues a system alarm.
Alarms display only when they are active. The menu title "ALARMS
(_)" includes the number of active alarms in parenthesis ().
When AUX is set to SYS and there is any alarm (e.g., failed
sensors, etc.), the AUX terminal has 24 Vac out.
