Typical Backup Thermostat Wiring
If the controller or a module fails, the backup thermostats will activate the dedicated fan
or heater as soon as temperature reaches the set point of the thermostat. The thermostat
must be accessible for adjustment and must be set at 3 to 5 degrees above the fan’s set
point or 3 to 5 degrees under the heater set point.
