†
Displays number of times actuator has cycled.
1 cycles equals accrued 180 deg. of actuator movement in any direction.
Displays ERROR if voltage or torque is below actuator range.
EXHAUST STAGE 1 RELAY OUTPUT
Output of EXH1 terminal:
ON = relay closed
OFF = relay open
EXHAUST STAGE 2 RELAY OUTPUT
Output of AUX terminal; displays only if AUX = EXH2
ON = relay closed
OFF = relay open
Displays stage of mechanical cooling that is active.
SUPPLY FAN SPEED
Displays speed setting of fan on a 2-speed fan unit.
HEAT DEMAND STATUS
Displays status of heat demand on a 2-speed fan unit.
SUPPLY AIR SETPOINT
Setpoint determines where the economizer will modulate the OA damper
to maintain the mixed air temperature. See Note 2.
COMPRESSOR LOW TEMPERATURE LOCKOUT
Setpoint determines outdoor temperature when the mechanical cooling
cannot be turned on.
OA DRY BULB TEMPERATURE CHANGEOVER SETPOINT
Setpoint determines where the economizer will assume outdoor air tem-
perature is good for free cooling; e.g.; at 63°F (17°C) unit will economize
at 62°F (16.7°C) and below and not economize at 64°F (17.8°C) and
above. There is a 2°F (1.1°C) deadband. See Note 3.
ENTHALPY CHANGEOVER CURVE
(Requires enthalpy sensor option)
Enthalpy boundary "curves" for economizing using single enthalpy.
DEMAND CONTROLLED VENTILATION
Displays only if CO
sensor is connected. Setpoint for Demand Control
2
Ventilation of space. Above the setpoint, the OA dampers will modulate
open to bring in additional OA to maintain a space ppm level below the
setpoint.
VENTILATION MINIMUM POSITION AT LOW SPEED
Displays ONLY if a CO
sensor is NOT connected.
2
VENTILATION MINIMUM POSITION AT HIGH SPEED
Displays ONLY if a CO
sensor is NOT connected.

DCV MAXIMUM DAMPER POSITION AT LOW SPEED
Requires CO
sensor connected.

DCV MAXIMUM DAMPER POSITION AT HIGH SPEED
Requires CO
sensor connected.

DCV MINIMUM DAMPER POSITION AT LOW SPEED
Requires CO
sensor connected.

DCV MINIMUM DAMPER POSITION AT HIGH SPEED
Requires CO

EXHAUST FAN STAGE 1 SETPOINT AT LOW SPEED
Setpoint for OA damper position when exhaust fan 1 is powered by the
economizer.
EXHAUST FAN STAGE 1 SETPOINT AT HIGH SPEED
Setpoint for OA damper position when exhaust fan 1 is powered by the
economizer.
EXHAUST FAN STAGE 2 SETPOINT AT LOW SPEED
Setpoint for OA damper position when exhaust fan 1 is powered by the
economizer. Only used when AUX1-O is set to EHX2.
EXHAUST FAN STAGE 2 SETPOINT AT HIGH SPEED
Setpoint for OA damper position when exhaust fan 1 is powered by the
economizer. Only used when AUX1-O is set to EHX2.
