Remote Wall-Mounted Sensor with 55°F to 85°F Adjustment
(optional)
When the optional remote wall-mounted sensor with 55°F to 85°F adjustment dial is used,
the UVC will effectively write the value of the set point dial to the Space Temp Set Point
Input variable.
Note: If a network connection is using the Space Temp Set Point Input variable, do not use the
optional remote wall-mounted sensor with 55°F to 85°F adjustment.
– If it is intended that the LUI will be used by room occupants to adjust the Setpoint
Offset, then you must not use the optional remote wall-mounted sensor with 55°F to 85°F
adjustment. When using the optional remote wall-mounted sensor with 55°F to 85°F
adjustment, the UVC will ignore any Setpoint Offset changes made at the LUI.

Effective Set Point Calculations

The UVC calculates the effective set point (Effective Set Point Output) based on sev-
eral factors. These factors include the six occupancy set points for heating and cooling
(Occupancy Temperature Set Point), occupancy mode, the value of the network vari-
ables Space Temp Set Point Input, Set Point Offset Input, and the Set Point Shift Input
as well as the optional wall-mounted sensor's set point adjustment dial. As always,
network inputs have priority over hardwired connections.
The UVC determines if heating or cooling is required based on the current unit mode
(Heat/ Cool Mode Output) and then calculates the required set point for heating or cool-
ing. After calculating, the Effective Set Point Output network variable is set equal to the
calculated set point. The Effective Set Point Output is the temperature set point that the
UVC maintains, which normally appears on the keypad/display.

Effective Set Point Calculations for each Occupancy Mode
AbsOffsetOccupied = Setpoint - (OCS + OHS)/2
AbsOffsetStandby = Setpoint - (SCS + SHS)/2
Occupied and Bypass Modes
EffectiveCoolSetpoint = OCS + AbsOffsetOccupied + SetptOffset + OCSS
EffectiveHeatSetpoint = OHS + AbsOffsetOccupied + SetptOffset + OHSS
Standby Mode
EffectiveCoolSetpoint = SCS + AbsOffsetStandby + SetptOffset + SCSS
EffectiveHeatSetpoint = SHS + AbsOffsetStandby + SetptOffset + SHSS
Unoccupied Mode
EffectiveCoolSetpoint = UCS + UCSS
EffectiveHeatSetpoint = UHS + UHSS
Note: Italicized values are optional input. Value will be 0F in not used.
If both entering paths have
valid values, then the network
value has priority.
If both entering paths have
valid values, then the keypad/display value
has priority.
