Point Name/Description
Default/Range
Hardwired Sensor
– The type of sensor used on the controller's
RH/CO2
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.

RH Control
– Enables or disables zone dehumidification control if valid RH sensor
values are available.

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
Remote
Occupancy
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.

CO2 Sensor Min Input Volts
– The lowest voltage that should be read from the
hardwired CO
2
sensor.
D:

CO2 Sensor Value @ Min Volts
– The ppm value that correlates to the hardwired CO
2
sensor's low voltage reading.
D:
R:
0 ppm
0 to 9999 ppm
CO2 Sensor Value @ Max Volts
– The ppm value that correlates to the hardwired CO
2
sensor's high voltage reading.
D:
R:
2000 ppm
0 to 9999 ppm
PD (Pressure Dependent) Control :
Damper Motor Travel Time
– The actuator's travel time from full closed to full
open. This field is fixed at 205 seconds.
D: 205 seconds
