Status Screen 1 - Compressor 1 & 2 Enable
and Current Position
RSM #1-4 Status
Compressor 1: ON/OFF
Compressor 2: ON/OFF
Comp Position: 0%
Line 2 Compressor 1 Enabled or Disabled
Current status of the fi rst Compressor.
Line 3 Compressor 2 Enabled or Disabled
Current status of the second Compressor.
Line 4 Current Position
Current position of the Modulating Compressor.
Status Screen 2 - Coil (Saturation) Temp &
Setpoint & Suction Pressure
RSM #1-4 Status
Coil Temp: 0.0ºF
Coil Setpt: 0.0ºF
Suction Pr: XXX PSI
Line 2 Coil (Saturation) Temperature
If a Suction Pressure Transducer has been installed and
confi gured on the unit, the calculated Evaporator Coil
Suction (Saturation) Temperature will appear on this
line. If not, this line will display 0°F.
Line 3 Coil (Saturation) Temperature Setpoint
During DX dehumidifi cation, compressor(s) will be
staged/modulated to maintain this Coil Suction
(Saturation) Temperature Setpoint. If indoor humidity
reset of the Coil Setpoint has been confi gured, this will
be the current calculated setpoint.
Line 4 Suction Pressure
This is the current Suction Pressure.
