Description
Rht Gain is an adjustable item which sets the "Gain" used in
the PI control function for controlling the reheat valve.
LSC Lo Gain is an adjustable item which sets the "Gain" used
in the PI control function for controlling the liquid subcooling
reheat valve .
Rht PAT is an adjustable item which sets the "project ahead
time" used in the PI control function for controlling the reheat
valve .
Rht Max Chg an adjustable item that sets the maximum value
for an increase or decrease for controlling the reheat valve .
-
An adjustable item to choose Dehumidification compressor
control; either Leaving Coil Temperature or Reheat control.
An adjustable item to select the Minimum Variable
Compressor Speed when DH Priority is LCT .
Curr Htg Stg is a status only item that displays the current
heating stage of the unit .
Description
Min Exh T Diff is an adjustable item that sets a differential below
the calculated potential energy recovery exhaust air frosting
point . When the ER Exh T falls below the calculated frosting
point by more that this value, the energy wheel will be driven to
its minimum speed, or turned OFF, to prevent frosting .
Max Exh T Diff is an adjustable item that sets a differential
above the calculated potential energy recovery exhaust air
frosting point . Once the wheel is driven to minimum speed,
or turned off, to prevent frosting, it is driven back to maximum
speed, or turned ON, only when ER Exh T rises back above the
calculated frosting point by more that this value .
ER Whl Stg Tm is an adjustable item used to set a minimum
time period for operating at either the minimum or maximum
speed before action is taken to change speed during the frost
protect mode of operation .
ER Whl Off Tm is an adjustable item used to set the minimum
amount of time the energy wheel will remain off after being
turned OFF due to a frosting/condensation condition .
ERWhleMinCap is the minimum allowed energy wheel capacity .
Intersect Pt is the calculated intersection point with saturation
line for the process line between the OAT at 95% RH and the
actual return air temperature and return air humidity .
RARelHum is a status only item of the current sensor return air
relative humidity reading .
FstMgmtMeth is the selected frost management method .
