Point Name/Description
Default/Range
Hardwired Sensor
–
The type of sensor used on the controller's IN-01 hardwire input.
This setting determines the control channel input function.
Options:
RH Sensor
–
Relative humidity for zone dehumidification
IAQ Sensor
–
Indoor air quality for DCV control
NOTE
RH and IAQ are also available with communicating ZS RH and CO
2
sensors.

Min Setpoint Separation
–
Minimum separation that must be maintained between the
heating and cooling setpoints.
D:
R:
4 °F (2.2 °C)
2 to 10 °F
(1.1 to 5.5 °C)
Occ Override Normal Logic State
–
The normal state of the controller's IN-04 input. If
the input's contact is the same state as the configured state, the controller follows its
controlling schedule. If the contact is in the opposite state of the configured state, the
controller is forced into the unoccupied mode.
