SET THERMOSTAT DIP SWITCHES

The thermostat DIP switches provide the thermostat
with an interface to the single zone HVAC system. See
Table 7 for DIP switch settings. The thermostat DIP switches
are located on the back of the thermostat. See Fig. 13. Set
the DIP switches for the desired thermostat features and the
system being controlled.
IMPORTANT: The thermostat configuration must match
the application, or the control logic will not function
properly.
