The heat mode of operation will NOT replace a furnace for heating the RV in cold weather. The intent is to remove the chill on cool days or mornings. For best results when using your Electric Heater Option:
1
Select "OPT HEAT".
2
The heat strip will come on and begin heating.
3
When desired temperature level in RV is reached, the thermostat sensor will cycle the optional heat strip OFF.
When desired temperature level in RV is reached, move the selector switch to "OFF" position or "FAN" position. The thermostat does NOT control the fan/heater ON/OFF cycle.
