Ambient Control kit at outdoor unit to control fan the speed and or its cycling Be sure to inform your installer of the units application and requirements before the unit is selected or installed so that the Low Ambient Control can be installed at the very beginning This will help to keep the coil from freezing up during cooling in low ambient temperatures 9 Heat pump systems are not supposed to be used as the only source of heating especially for areas where ambient temperatures drop below 35F for most of heating season 10 13SEER units are built with fixed speed compressor unlike DC inverter type and are only designed for heating applications in mild ambient temperatures The lowest temperatures that the 13SEER units have been tested to is 17F But the units can still generate a pretty good amount of heat even when ambient temperatures go to lower ranges When ambient temperatures drop to lower ranges heat pump units generate less capacity at lower efficiency If you want to use these units to heat spaces in northern regions where yearly heating hours are more than yearly cooling hours an indoor unit that has the backup electric heat should be installed along with the heat pump units This way the back up heater can make up heat when the heat pump unit doesn t generate enough heat or take its place to heat up your space when the heat pump efficiency HSPF drops close to or below 1 0 You can ask the installer to set up the control or switch to
