Series - Installation, Operation and Maintenance
• Tol – Indicates how far outside of the Min – Max range the value can be before the sensor is flagged as
failed.
• Offs – This parameter can be used to calibrate the sensor to a known standard. The signed value of this
parameter is added to actual value read from the sensor.
• Ovrd – This parameter can be used to override the value read from the sensor. When set to a non-0.0 value,
the control logic will use this parameter instead of the value read from the sensor.
• Min – For thermistor inputs, this parameter indicates the low end of the expected range for the sensor value.
For a 4-20mA input, the value of this parameter indicates the sensor value at 4 mA.
• Max - For thermistor inputs, this parameter indicates the high end of the expected range for the sensor value.
For a 4-20mA input, the value of this parameter indicates the sensor value at 20 mA.
The following analog input screens are available. Factory default values are shown for non-zero parameters:
• Discharge Pressure - Tol = 20, Min = 0.0, Max = 652
• Suction Pressure - Tol = 20, Min = 0.0, Max = 652
• Return Relative Humidity - Tol = 15.0, Min = 0.0, Max = 100.0
• Suction Temperature - Min = 0.0, Max = 100.0
• Return Air Temperature - Min = -20.0, Max = 195.0
• Pool Water Temperature - Min = -20.0, Max = 195.0
• Surface Temperature - Min = -20.0, Max = 195.0
• Outside Air Temperature - Min = -20.0, Max = 195.0
Analog Outputs
The following analog output applies for RoofComPak models (units with EC fans):
• SupFanSpd - Supply Fan Speed the actual analog output DC voltage multiplied by 10. The RPM is shown
on the second line with “Nrm” being the RPM from the control logic. If the “Ovrd” value is set to a non-zero
value, the analog output voltage will correspond to the “Ovrd” RPM value instead of the “Nrm.” - Nrm =
1600, Min Val = 0000 =00.0V, Max Val = 1750 = 10.0V
UNIT CONFIGURATION
Installed Options
This menu contains parameters that indicate the hardware options installed in the dehumidifier. The parameters
are set by the factory and do not typically require modification. The following parameters are available:
Unit Type – AW or HCD. AW units contain a pool water heating condenser. HCD units do not contain a pool
water heating condenser.
• Air Cooling – Yes or No. Set to Yes if the unit or system contains an air or water cooled condenser for
external heat rejection.
• Economizer – Yes or No. Set to Yes if the system is equipped with optional field provided and installed
dampers for economizer operation.
• LonWorks Board – Yes or No. Set to Yes if the controller serial card slot contains a LonWorks
PW Condenser –
Partial or Full.
Most dehumidifiers should be set for Partial. Contact factory service before changing this parameter to Full.
An improper setting of Full will cause a high pressure fault condition and possible equipment damage.
