Backup Control
This section explains when backup control is used. For
example, if batteries in the wireless indoor sensors are
depleted.
If the Thermostat is Part of the Temperature
Average
1. The thermostat controls the system using the remaining
sensors that are part of the temperature average.
2. If there are no remote indoor sensors remaining, the
thermostat controls the system using its internal sensor.
3. If the internal thermostat sensor is not available and a
Return Air Sensor is connected, the Backup Control in
the EIM is used. The backup control maintains 55 °F in
heat, 85 °F in cool and operates the fan continuously to
sense and control temperature.
If the Thermostat is NOT Part of the
Temperature Average
1. The thermostat controls the system using the remaining
sensors that are part of the temperature average.
2. If there are no remote indoor sensors remaining and a
Return Air Sensor is connected, the Backup Control in
the EIM is used. The backup control maintains 55 °F in
heat, 85 °F in cool and operates the fan continuously to
sense and control temperature.
