Switch 8 – Thermostat Control Logic
This switch has two functions based on the position of Sw6. When the thermostat
is set as a programmable thermostat (Sw6 ON), Sw8 determines whether a
commercial program or residential program will be followed. When Sw6 is OFF,
the thermostat is used as a non-programmable thermostat. This switch will then
set a single setpoint mode (Sw8 OFF) or (Sw8 ON) for separate heating and cooling
setpoints. The two setpoint mode also permits the user to select a separate day
and night setpoint if required.
