NOTES
Displays number of times actuator has cycled.
1 cycles equals 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
ENERGY RECOVERY VENTILATOR
Output of AUX terminal; displays only if AUX = ERV
Displays stage of mechanical cooling that is active.
Displays the stage of heat pump heating 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.
COMPRESSOR LOW TEMPERATURE LOCKOUT
Setpoint determines outdoor temperature when the mechanical cooling
cannot be turned on. Commonly referred to as the Compressor lockout.
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 unit will economize at 62 F
and below and not economize at 64 F and above. There is a 2 F dead-
band.
ENTHALPY CHANGEOVER CURVE
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
Displays ONLY if a CO sensor is NOT connected.
2
DCV MAXIMUM DAMPER POSITION
Displays only if a CO sensor is connected. Used for Vbz (ventilation
2
max cfm) setpoint. Displays 2 to 10 V if <3 sensors (RA,OA, and MA). In
AUTO mode dampers controlled by CFM.
If OA, MA, RA, and CO sensors are connected and DCV CAL ENABLE
2
is set to AUTO mode, the OA dampers are controlled by CFM and dis-
plays from 100 to 9990 CFM.
With 2-speed fan units VENT L (low speed fan) and MIN POS H (high
speed fan) settings are required. Default for VENTMAX L is 3.2V and
VENTMAX H is 2.8V
DCV MINIMUM DAMPER POSITION
Displays only if a CO sensor is connected. Used for Ba (ventilation min
2
cfm) setpoint. Displays 2 to 10 V if <3 sensors (RA, OA, and MA). Va is
only set if DCV is used. This is the ventilation for less than maximum
occupancy of the space. In AUTO mode dampers controlled by CFM.
If OA, MA, RA, and CO sensors are connected and DCV CAL ENABLE
2
is set to AUTO mode, the OA dampers are controlled by CFM and dis-
plays from 100 to 9990 CFM.
With 2-speed fan units VENTMIN L (low speed fan) and MIN POS H
(high speed fan) settings are required. Default for VENTMIN L is 3.2V
and VENTMIN H is 2.8V
ENERGY RECOVERY VENTILATOR UNIT OUTDOOR AIR TEM-
PERATURE SETPOINT
Only when AUX1 O = ERV
EXHAUST FAN STAGE 1 SETPOINT
Setpoint for OA damper position when exhaust fan 1 is powered by the
economizer.
With 2-speed fan units Exh1 L (low speed fan) and Exh1 H (high speed
fan) settings are required. Default for Exh1 L is 65% and Exh1 H is 50%
EXHAUST FAN STAGE 2 SETPOINT
Setpoint for OA damper position when exhaust fan 2 is powered by the
economizer. Only used when AUX1 O is set to EHX2.
With 2-speed fan units Exh2 L (low speed fan) and Exh2 H (high speed
fan) settings are required. Default for Exh2 L is 80% and Exh2 H is 75%
