MENU/SUB-MENU DESCRIPTIONS
HVAC Settings – this menu item allows you to set the parameters of the HVAC system
type the thermostat is connected to. The configurable items are:
1. System Type – Conventional (default), Heat Pump, 2-Pipe, and 4-Pipe are the
selectable types.
2. Cool Limit – determines the lowest possible cool setpoint that can be set on the
thermostat. This item can be set from 55 (default) to 78.
3. Heat Limit – determines the highest possible heat setpoint that can be set on
the thermostat. By default, this item is set to 90 and the maximum heat setpoint
is 91.
4. Fan Stages – determines the number of fan stages supported by the HVAC
system and can be set from 0 – 3. By default, this item is set to 1.
5. Cool Stages – determines the number of cool stages supported by the HVAC
system and can be set from 0 – 2. By default, this item is set to 1.
6. Heat Stages – determines the number of heat stages supported by the HVAC
system and can be set from 0 – 3. By default, this item is set to 1.
7. Differential – HVAC differential is the difference between the current
temperature and the setpoint that is used to turn on the second stage. For
example, if the differential is 4, with a setpoint of 70, and current temperature
= 72, only the first stage cool will be on. If you change the setpoint from 70 to
68, the difference would be 4 degrees and the 2nd stage would come on. The
default is 4 and can be set from 1 to 9.
