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.

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

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.
