En3 - 3rd Stage Enthalpy Cooling Lockout
En3 provides an enthalpy differential to the En2 setting (add this differential to the En2
value). If outdoor enthalpy is below this value, the 3rd stage of cooling is not allowed.
5° 0 - 20
nSU - Night Setup - Cooling
This value is added to the space cooling setpoint (SSP) for unoccupied periods. If the
cooling setpoint (SSP) is 75° during the occupied mode, and Nsu is 9, then during unoc-
cupied modes, the cooling setpoint will be 84°F (75 +9).
9°F 0 - 35
nSb - Night Set Back – Heating
This value is the amount subtracted from the space heating setpoint in the unoccupied
mode. SSP - Hso - nSb ~ 75 - 5 - 9 = 61°F space heating setpoint in the unoccupied
mode.
9°F 0 - 35
iCt - Heating Integration Constant (requires room sensor)
This adjustable parameter denes the integration time used during heating. iCt has a
default value of zero and is rarely adjusted.

dAo - Space Sensor Calibration (requires room sensor)
Allows a small sensor offset when space wires add signicant resistance.

resistance.
rHE - Reheat Enabled or Disabled during Unoccupied Mode
Yes or No input. Default to “No”, unless room is equipped with an RH input or controller.
“Yes” will allow only the reheat pump to be enabled upon a rise in space RH.
Yes Yes or No
PUt - Pull Up Time - Heating (requires room sensor)
Time frame allows for fast heating of space when transitioning from unoccupied to occu-
pied modes. The unit will switch to occupied mode the selected number of minutes before
the scheduled time.

dCH - Standard Discharge Air Temperature Setpoint (Primary Setpoint) .
If the reset option is disabled, the dCH becomes the primary neutral air cooling dis-
charge air temperature setpoint. If the reset option is active, this is the maximum cooling
value based on outdoor air conditions. The discharge air temperature will not change to
a higher value than dCH regardless of the outside air temperature. .
70°F
50 - 115°F
dCL - Outside Air Reset Option
The value of the neutral discharge air cooling setpoint when the outside air temperature
is at its warmest value to allow maximum cooling. The discharge air temperature will not
change to a lower value than dCL regardless of the outside air temperature. The default
value disables reset functionality.
80°F 49 - 115°F
oC2 - Outdoor Reset Dry Bulb Cooling – High Setting
The value of the outside air temperature corresponding to the dCL coldest cooling set-
point.
60°F 20 - 70°F
oC3 - Outdoor Reset Dry Bulb Cooling – Low Setting
The value of the outside air temperature corresponding to the dCH warmest cooling
setpoint.
20°F
-40 - 65°F
dHL - Standard Discharge Air Setpoint (Primary Setpoint)
If the reset option is disabled, the dHL becomes the primary neutral air heat discharge air
setpoint. dHL is the value of the discharge air heating setpoint when the outside air tem-
perature is at its warmest value to allow minimum heating. The discharge air temperature
will not change to a lower value than dHL regardless of the outside air temperature.
70ºF
45 - 120°F
dHH - Outdoor Air Reset Option
dHH is the value of the discharge air heating setpoint when the outside air temperature
is at its coldest value to allow maximum heating. The discharge air temperature will not
change to a higher value than dHH regardless of the outside air temperature.
70ºF 50 - 115ºF
oH2 - Outdoor Reset Dry Bulb Heating – High Setting
The value of the outside air temperature corresponding to the dHL low heating setpoint
value.
60ºF
20 - 70ºF
