AV.41
Cfg_CoolingPropBand
Advanced
Configuration value that represents the range through which the controller will
modulate the cooling output from 0 to 100%.
Present Value
COV Increment (0.5) 1ºF to 10ºF or 0.5ºC to 5ºC, Resolution 1ºF/0.5ºC
AV.42
Cfg_CoolingDeadBand
Advanced
Configuration value that represents the range at which the controller will not
take action when above the zone setpoint.
Present Value
COV Increment (0.1) 0°F to 10°F or 0°C to 5°, Resolution 0.2ºF/0.1ºC
AV.50
Cfg_IntegralTimeCooling
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)
0 to 250 seconds, Resolution 5 seconds
AV.58
Cfg_ChangeOverSetpoint
Advanced
Configuration value of the temperature at which the primary air from the central
system is considered to be in cooling or heating. Note that there is a 1.5°C
(2.7°F) dead band on each side of the setpoint.
Present Value
COV Increment (0.5)
50°F to 104°F or 10°C to 40°C,
Resolution 1ºF/0.5ºC
AV.59
Cfg_ChangeOverDelay
Integrator Configuration value that represents the delay in changeover.
Present Value
COV Increment (1)
0 to 180 minutes, Resolution 15 minutes
AV.61
Cfg_NoOccOverrideDelay
Integrator
Configuration time in minutes when unoccupied and an override has been
activated on the controller.
Present Value
COV Increment (1)
0 to 180 minutes, Resolution 15 minutes
AV.70
Cfg_AnalogOutput1 Min
Advanced
This value represents the minimum control signal of the controlled element. If
the signal is 0 to 10Vdc then the minimum value is 0 Volts and if the signal is 2
to 10 Vdc then minimum value is 2 Volts. This value is the 0 position at 0%
demand. If set at 2 Volts, a 2 Volt is applied continuously even when there is no
demand. It cannot be used to set the minimum starting activation position.
Present Value
COV Increment (0.5) 0 Volt to AV.71, Resolution 0.1 Volt
AV.71
Cfg_AnalogOutput1 Max
Advanced
This value represents the maximum control signal of the controlled element. If
the signal is 0 to 10Vdc or 2 to 10Vdc then the maximum value is 10 Volts. It
can also be used to limit the maximum output of the controller. If the control
signal is 0 to 10Vdc and the maximum voltage value is set to 8 Volts, the
controlled element will never go over 80% of its total capacity.
Present Value
COV Increment (0.5) AV.70 to 10.0 Volt, Resolution 0.1 Volt
AV.72
Cfg_AnalogOutput2 Min
Advanced
This value represents the minimum control signal of the controlled element. If
the signal is 0 to 10Vdc then the minimum value is 0 Volts and if the signal is 2
to 10 Vdc then minimum value is 2 Volts. This value is the 0 position at 0%
demand. If set at 2 Volts, a 2 Volt is applied continuously even when there is no
demand. It cannot be used to set the minimum starting activation position.
Present Value
COV Increment (0.5) 0 Volt to AV.73, Resolution 0.1 Volt
AV.73
Cfg_AnalogOutput2 Max
Advanced
This value represents the maximum control signal of the controlled element. If
the signal is 0 to 10Vdc or 2 to 10Vdc then the maximum value is 10 Volts. It
can also be used to limit the maximum output of the controller. If the control
signal is 0 to 10Vdc and the maximum voltage value is set to 8 Volts, the
controlled element will never go over 80% of its total capacity.
Present Value
COV Increment (0.5) AV.72 to 10.0 Volt, Resolution 0.1 Volt
AV.88
Cfg_DamperMaxPositionCool
Integrator
Configuration value that represents the maximum damper position when the
system is in cooling mode and the zone is in 100% cooling demand.
Present Value
COV Increment (1)
AV.90 to 100%, Resolution 1%
AV.89
Cfg_DamperMaxPositionHeat
Integrator
Configuration value that represents the maximum damper position when the
system is in heating mode and the zone is in 100% heating demand.
Present Value
COV Increment (1)
AV.90 to 100%, Resolution 1%
AV.90
Cfg_DamperMinPosition
Integrator
Configuration value that represents the minimum damper position when the
system is in cooling or heating mode (at all times).
Present Value
COV Increment (1)
0% to 100%, Resolution 1%
AV.92
Cfg_DamperMaxPositionReheat
Integrator
Configuration value that represents the maximum damper position when the
system is in cooling mode, but the zone is requesting heat. This configuration is
only available if the zones are equipped with a modulating duct reheat.
Present Value
COV Increment (1)
0% to 100%, Resolution 1%
