Filter Service Hours
This refers to the timer set for the Dirty Filter Alarm. After the number of runtime hours set on this point is exceeded the corresponding alarm will be generated, and must be manually cleared on the alarm reset screen after the maintenance has been completed. The timer will then begin counting its runtime again for the next maintenance interval.
Factory Default = 600 hr
NOTE: Setting this configuration timer to 0, disables the alarm.
Supply Fan Service Hours
This refers to the timer set for the Supply Fan Runtime Alarm. After the number of runtime hours set on this point is exceeded the corresponding alarm will be generated, and must be manually cleared on the alarm reset screen after the maintenance has been completed. The timer will then begin counting its runtime again for the next maintenance interval.
Factory Default = 0 hr
NOTE: Setting this configuration timer to 0, disables the alarm.
Compressor1 Service Hours
This refers to the timer set for the Compressor 1 Runtime Alarm. After the number of runtime hours set on this point is exceeded the corresponding alarm will be generated, and must be manually cleared on the alarm reset screen after the maintenance has been completed. The timer will then begin counting its runtime again for the next maintenance interval.
Factory Default = 0 hr
NOTE: Setting this configuration timer to 0, disables the alarm.
Compressor2 Service Hours
This refers to the timer set for the Compressor 2 Runtime Alarm. After the number of hours set on this point is exceeded the corresponding alarm will be generated, and must be manually cleared on the alarm rest screen after the maintenance has been completed. The timer will then begin counting its runtime again for the next maintenance interval
Factory Default = 0 hr
NOTE: Setting this configuration timer to 0, disables the alarm.
Cooling
Number of Compressor Stages
This refers to the number of mechanical cooling stages available on a specific unit. Set this point to “One Stage” if there is one compressor in the specific unit, set to “Two Stage” if there are two compressors in the unit, and set to “None” if economizer cooling ONLY is desired.
Factory Default = One Stage for 1 compressor units Two Stage for 2 compressor units
Cooling/Econ SAT Low Setpt
The supply air temperature must remain above this value to allow cooling with the economizer and/or compressors. There is 5_F plus and minus deadband to this point. If the SAT falls below this value during cooling, all compressors will be staged off. The economizer will start to ramp down to minimum position when the SAT = this configuration +5_F.
Factory Default = 50_F Range =
Cooling Lockout Temp
This defines the minimum outdoor air temperature that cooling mode can be enabled and run. If the OAT falls below this threshold during cooling, then compressor cooling will not be allowed.
Factory Default = 45_F Range =
Heating
Heating SAT High Setpt
The supply air temperature must remain below this value to allow heating. There is 5_F plus and minus deadband to this point. If the SAT rises above this value during heating the heat stages will begin to decrease until the SAT has dropped below this value.
Factory Default = 120_F Range =
Heating Lockout Temp
This defines the maximum outdoor air temperature that heating mode can be enabled and run. If the OAT rises above this threshold during heating, then heating will not be allowed.
Factory Default = 65_F Range =
Inputs
NOTE: For installation of inputs and field installed accessories, refer to the appropriate sections.
Input 3
This input is a discrete input and can be configured to be one of five different inputs: No Function, Compressor Safety, Fan Status, Filter Status, or Remote Occupancy. This input can also be configured to be either Normally Open (N/O) or Normally Closed (N/C). Input 3 is factory wired to pin
Factory Default = Compressor Safety and N/O
NOTE: Compressor Safety input comes from the CLO board.
