DehuHyst
Dehumidification
Hysteresys
Default = 5 % RH
Conditional parameter to Humidity models
VT735xX5x00(X)
Humidity control hysteresis. Used only if dehumidification
sequence is enabled:
Range is: 2 to 20% RH
DehuCool
Maximum
Dehumidification
Cooling output
Default = 100 %
Conditional parameter to Humidity models
VT735xX5x00(X)
Maximum cooling valve position when dehumidification is
enabled. This can be used to balance smaller reheat loads
installed relative to the capacity of the cooling coil.
Range is: 20 to 100 %
St-By TM
Stand-by Timer value
Default = 0.5 hours Time delay between the moment when the PIR sensor
detected the last movement in the area and the time when
the Terminal Equipment Controller stand-by mode and
setpoints become active.
Range is: 0.5 to 24.0 hours in 0.5hr increments
Unocc TM
Unoccupied Timer value
Default = 0.0 hours Time delay between the moment when the Terminal
Equipment Controller toggles to stand-by mode and the
time when the Terminal Equipment Controller unoccupied
mode and setpoints become active.
The factory value or 0.0 hours: Setting this parameter to its
default value of 0.0 hours disables the unoccupied timer.
This prevents the Terminal Equipment Controller to drift
from stand-by mode to unoccupied mode when PIR
functions are used
Range is: 0.0 to 24.0 hours in 0.5hr increments
St-By HT
Stand-by heating
setpoint
Default value = 69 °F The value of this parameter should reside between the
occupied and unoccupied heating setpoints and make sure
that the difference between the stand-by and occupied
value
can be recovered in a timely fashion when movement is
detected in the zone.
Stand-by heating setpoint range is: 40 to 90 °F
( 4.5 to 32.0 °C )
St-By CL
Stand-by cooling
setpoint limit
Default value = 78 °F The value of this parameter should reside between the
occupied and unoccupied cooling setpoints and make sure
that the difference between the stand-by and occupied
value can be recovered in a timely fashion when movement
is detected in the zone.
Stand-by cooling setpoint range is: 54 to 100 °F
( 12.0 to 37.5 °C )
Unocc HT
Unoccupied heating
setpoint
Default value = 62 °F Unoccupied heating setpoint range is:
40 to 90 °F ( 4.5 to 32.0 °C )
