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

Maximum heating setpoint limit 
Default value =

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 = 

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. 

Minimum On/Off operation time of cooling & heating 
stages.  

 

IMPORTANT, anti-short cycling can be set to 0 minutes 
for equipment that posses their own anti cycling timer. Do 
not use this value unless the equipment is equipped with 
such internal timer. Failure to do so can damage the 
equipment.
