Setpoint determines where the economizer will modulate the OA damper
to maintain the mixed air temperature.
Setpoint determines outdoor temperature when the mechanical cooling
cannot be turned on. Commonly referred to as the Compressor lockout.
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.
Enthalpy boundary "curves" for economizing using single enthalpy.
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.
Displays ONLY if a CO
sensor is NOT connected.
2
Displays only if a CO
sensor is connected. Used for Vbz (ventilation max
2
cfm) setpoint. Displays 2 to 10 V if <3 sensors (RA, OA and MA). In
AUTO mode dampers controlled by CFM.
Displays only if a CO
sensor is connected. Used for Va (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.
Only when AUX1 O = ERV
Setpoint for OA damper position when exhaust fan 1 is powered by the
economizer.
Setpoint for OA damper position when exhaust fan 2 is powered by the
economizer. Only used when AUX is set to EHX2.
Display order = MM/DD/YY
Setting order = DD, MM, then YY .
Sets economizer controller in degrees Fahrenheit or Celsius.
CONV = conventional; HP O/B = Enable Heat Pump mode. Use AUX2 I
for Heat Pump input from thermostat or controller.
In CONV mode: SD + Enables configuration of shutdown (default); W =
Informs controller that system is in heating mode. In HP O/B mode:
HP(O) = energize heat pump on Cool (default); HP(B) = energize heat
pump on Heat.
Sets the economizer controller for operation of 1 speed or 2 speed
supply fan.
This is the capacity of the RTU. The value is found in the Project
Submittal documents for the specific RTU.
S NONE = not configured (output is not used)
S ERV = Energy Recovery Ventilator
S EXH2 = second damper position relay closure for second exhaust fan
S SYS = use output as an alarm signal
When using a setback thermostat with occupancy out (24 Vac), the 24
Vac is input "INPUT" to the OCC terminal. If no occupancy output from
the thermostat then change program to "ALWAYS" OR ad a jumper from
terminal R to OCC terminal.
