Heat Pump or Heat Strip Mode: If you have this option, cycling to this mode will put the air conditioner
into heat pump mode, or if you have a heat strip, will activate the heat strip. These act as an alternative
to running the furnace when heat is needed.
Heat pump operation is basically an air conditioner running backwards in the sense that instead of
cooling the inside air and moving hot air outside, it cools the outside air and moves heat inside. Heat
pumps operate reasonably well in mild temperatures, but as outside temperatures fall, they have
increasing difficulty extracting heat from the cold outside air. With some thermostats, at an outside
temperature of 30 degrees, the thermostat will shut of the heat pump and start the furnace.
Heat strips are simple electric resistance heating devices.
A heat pump or heat strip can assist you in conserving propane, at the cost of using more electricity
instead.
Checking and Changing the Set Point Temperature
When the thermostat is set to OFF, pressing either the + or – button will display the current
temperature of the RV on the LCD display.
When the thermostat is set to heat or cool, pressing the + or – button will increase or decrease the set
point temperature.
Multizone Bedroom LCD Thermostat
The optional 2
nd
air conditioner installed in the bedroom often will have a thermostat such as pictured
below. Although it is capable of controlling multiple zones,
only Zone 1 is used. Notice that there is an ON/OFF switch
on the bottom edge of the thermostat.
Similar to the living room thermostat, the MODE button will
cycle the unit to the Cool mode. Since this thermostat
controls only the bedroom air conditioner, unless the
bedroom air condition includes a heat pump option, the
other modes don’t do anything.
A separate FAN button allows you to set the fan speed to
LOW, MEDIUM, HIGH, or AUTO. Most of the time, setting
to AUTO works best. In AUTO, if the air temperature is 8
NOTE: In sub-freezing weather, on models with heated underbelly, running the furnace pumps heat
into the underbelly, helping to keep water in water lines and tanks from freezing. If you rely entirely
on a heat pump or heat strip (or other electric heaters inside the coach), your plumbing could freeze
at a higher temperature than if you use the furnace.
