releasing that heat indoors.
To get the best performance from your heat pump, don’t
change the room thermostat very often. Raising the heat setting
2–3 degrees will cause the Zoneline to use its electric heating
elements in order to reach the new temperature setting quickly.
There is a 3-minute minimum compressor run time at any setting
to prevent short cycling.
The fans start before the compressor and stop after the
compressor cycles off.
When the outdoor temperature is lower than 25°F, heat is
provided by the electric heater instead of by the heat pump.
The electric heating elements use much more electricity than
heat pumps and cost more to operate.
