operation, this will be the MSAS (supply-air set point + reset)
for cooling and the heating set point for heating.
Press to display the control temperature. This display is
the actual supply-air temperature leaving the unit.
(Temperature) — The system temperature subfunc-
tion displays the readings at the temperature sensing ther-
mistors. To read a temperature, press , then scroll to the
desired temperature reading by pressing .
(Pressure) — The system pressure subfunction dis-
plays suction, discharge, low-pressure switch status, building
pressure, and static pressure.
(Inputs) — This subfunction displays the rest of the
system inputs. Press , then press . The compres-
sor A1 status is displayed with either ON or OFF based on
whether the compressor is running or not. Press to access
additional system inputs. Some inputs can be used forced by
entering a value to replace the actual value. For example, press
until the ENT display appears. The display will show ENT
LOW or ENT HGH, indicating that the enthalpy is good
(LOW) or bad (HGH).
