Configuration value used to set the user minimum permitted setpoint of the
zone in occupied/day mode.
Present Value
COV Increment (0.5)
-40°F to 212°F or -40°C to 100°C (-40°F/-40°C to
AV.17), Resolution 0.02ºF/0.01°C
AV.17
Cfg_MaxSetpoint
Integrator
Configuration value used to set the user maximum permitted setpoint of the
zone in occupied/day mode.
Present Value
COV Increment (0.5)

212°F/100°C), Resolution 0.02ºF/0.01°C
AV.18
UnoccupiedCoolSetpoint
Integrator
Configuration value of the cooling setpoint during no occupancy mode. The
cooling setpoint is restricted by the heating setpoint.
Present Value
COV Increment
50°F to 104°F or 10°C to 40°C (50°F/10°C to
AV.12), Resolution 0.02ºF/0.01°C
AV.19
UnoccupiedHeatSetpoint
Integrator
Configuration value of the heating setpoint during no occupancy mode for
return air temperature. The heating setpoint is restricted by the cooling setpoint.
Com lost RAT control setpoints.
Present Value
COV Increment
50°F to 104°F or 10°C to 40°C (AV.11 to
104°F/40°C), Resolution 0.02ºF/0.01°C
AV.20
HeatingDemand
Integrator
Status value that represents the heating demand in percentage for the Heating
Ramp. The heating demand value is based on zone temperature, zone setpoint
and values set for the actual ramp (AV.21 and AV.22).
Read only
COV Increment (5)
0 to 100%, Resolution 0.5%
AV.21
Cfg_HeatingPropBand
Advanced
Configuration value that represents the range through which the controller will
modulate the heating output from 0 to 100%.
Present Value
COV Increment (0.5) 1ºF to 10ºF or 0.5ºC to 5ºC, Resolution 1ºF/0.5ºC
AV.22
Cfg_HeatingDeadBand
Advanced
Configuration value that represents the range where the controller will not take
action when below the zone setpoint.
Present Value
COV Increment (0.1) 0°F to 10°F or 0°C to 5°C, Resolution 0.2ºF/0.1ºC
AV.23
DuctReheatDemand
Integrator Status value that represents the reheat demand.
Read only
COV Increment (0.1) 0 to 100%, Resolution 0.1%
AV.24
Cfg_DuctReheatPropBand
Advanced
Configuration value that represents the range through which the controller will
modulate the reheat output from 0 to 100%.
Present Value
COV Increment (0.5) 1ºF to 10ºF or 0.5ºC to 5ºC, Resolution 1ºF/0.5ºC
AV.25
Cfg_DuctReheatDeadBand
Advanced
Configuration value that represents the range at which the controller will not
take action when below the zone setpoint.
Present Value
COV Increment (0.3) 0°F to 10°F or 0°C to 5ºC, Resolution 0.2ºF/0.1ºC
AV.26
PerimeterReheatDemand
Integrator Status value that represents the perimeter (baseboard) reheat demand.
Read only
COV Increment (5)
0 to 100%, Resolution 0.1%
AV.27
Cfg_PerimeterReheatPropBand
Advanced
Configuration value that represents the range through which the controller will
modulate the perimeter (baseboard) reheat from 0 to 100%.
Present Value
COV Increment (0.5) 1ºF to 10ºF or 0.5ºC to 5ºC, Resolution 1ºF/0.5ºC
AV.28
Cfg_PerimeterReheatDeadBand Advanced
Configuration value that represents the range at which the controller will not
take action when below the zone setpoint.
Present Value
COV Increment (0.1) 0°F to 10°F or 0°C to 5ºC, Resolution 0.2ºF/0.1ºC
AV.30
Cfg_IntegralTimeHeating
Advanced
Configuration value that represents the reciprocal of the integral time in
seconds (1/I or repeats per second). To obtain a slower reaction time, the value
of the integral must be small. To obtain a quicker reaction, the integral must be
bigger.
Present Value
COV Increment (5)
