Also make sure you check the alarm temperature of the freeze alarm. Some are fixed at a certain temperature, some you can adjust the alarm temperature. I would recommend you set the heat at about 10 degrees higher than the alarm temp. of the freeze alarm. For example the freeze alarm activates the alarm at 40 degrees – I recommend you set the heat in the house at 50 degrees. This will allow for some variation in temperature due to placement of the freeze alarm vs the house thermostat, harsh temperature drops during a storm or on real cold nights as well as short power outage. It may take some trial and error to get it right depending on your particular situation – so you may get a few “false” alarms if the temperature setting differential is to close.
