†
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.
MIXED 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
temperature 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 deadband.
DRYBULB SET is only displayed if the economizer has a single dry
bulb sensor.
Drybulb Differential will only show if using dual drybulb - i.e. when an
outdoor air temperature sensor C7250 is attached to OAT terminals
and C7400S sensor is wired to S-Bus and configured for RAT (return
air). Free cooling will be assumed whenever OA temp is at or below
RAT minus this drybulb setting.
ENTHALPY CHANGEOVER CURVE
(Requires enthalpy sensor option)
Enthalpy boundary "curves" for economizing using single enthalpy.
DEMAND CONTROLLED VENTILATION SETPOINT
Displays only if CO
sensor is connected. Setpoint for Demand
2
Controlled 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. Only displayed if controller is
set for single speed unit under FAN TYPE, and if DCV is NOT used.
VENTILATION MINIMUM POSITION AT LOW SPEED. Only displays
if unit is set for 2 or 3 speed and CO
1 heat and 1 cool then set for HEATING ventilation. If using 3 speed
with 1 heat and 2 cool then set for LOW SPEED COOLING
ventilation.
VENTILATION MINIMUM POSITION AT MEDIUM SPEED. Only
displays if unit is set for 3 speed with 1 heat and 2 cool, and CO
used. Set for HEATING ventilation.
VENTILATION MINIMUM POSITION AT HIGH SPEED. Only
displays if unit is set for 2 or 3 speed and CO
speed with 1 heat and 1 cool then set for COOLING ventilation. If
using 3 speed with 1 heat and 2 cool then set for HIGH SPEED
COOLING ventilation
DCV MAXIMUM DAMPER POSITION AT LOW SPEED. Only
displays if unit is set for 2 speed or 3 speed with 1 heat and 2 cool. IF
using 2 speed with 1 heat and 1 cool then set for HEATING
ventilation. If using 3 speed with 1 heat and 2 cool then set for LOW
SPEED COOLING
DCV MAXIMUM DAMPER POSITION AT MEDIUM SPEED. Only
displays if unit is set for 3 speed with 1 heat and 2 cool. Set for
HEATING ventilation.
DCV MAXIMUM DAMPER POSITION AT HIGH SPEED. Only
displays if unit is set for 2 speed or 3 speed with 1 heat and 2 cool. IF
using 2 speed with 1 heat and 1 cool then set for COOLING
ventilation. If using 3 speed with 1 heat and 2 cool then set for HIGH
