pwr del
Power-up delay
Default value = 10 seconds
On initial power up of the thermostat ( each time 24 Vac
power supply is removed & re-applied ) there is a delay
before any operation is authorized ( fan, cooling or
heating ). This can be used to sequence start up multiple
units / thermostat in one location.
10 to 120 seconds
Frost pr
Frost protection enabled
Default value = Off
On heat pump models the system mode
will be forced to EMERGENCY mode if
frost protection is activated
Off: no room frost protection
On: room frost protection enabled in all system mode at:
42 °F ( 5.6 °C )
Frost protection is enabled even in system Off mode
Off or On
heat max Maximum heating setpoint limit
Default value = 90 °F ( 32 °C )
Maximum occupied & unoccupied heating setpoint
adjustment. Heating setpoint range is:
40 to 90 °F ( 4.5 to 32.0 °C )
cool min Minimum cooling setpoint limit
Default value = 54 °F ( 12 °C )
Minimum occupied & unoccupied cooling setpoint
adjustment. Cooling setpoint range is:
54 to 100 °F ( 12.0 to 37.5 °C )
Pband Proportional Band setting
Default value = 2.0 °F ( 0.6 °C )
Adjust the proportional band used by the thermostat PI
control loop.
Warning. Note that the default value of 2.0 °F ( 0.6 °C )
gives satisfactory operation in most normal installation
cases. The use of a superior proportional band different
than the factory one is normally warranted in applications
where the thermostat location is problematic and leads to
unwanted cycling of the unit. A typical example is a wall
mounted unit where the thermostat is installed between
the return and supply air feeds and is directly influenced
by the supply air stream of the unit.

Anticycle Minimum on/off operation time for stages
Default value = 2 minutes
Anti-short cycling can be set to 0 minutes
for equipment that posses their own anti
cycling timer. Do not use that value
unless the equipment is equipped with
such internal timer. Failure to do so can
damage the equipment.
