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.

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.
Please 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 =

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.
