Let the heat pump do the cooling. The Cooling Module Passive enables your heat pump to deliver cool air to your home. The module only starts up when you want cool air. Otherwise, your heat pump works as normal.
The cooling module works with passive cooling - also known as free cooling - which is ideal in homes that only occasionally require cooling or if you want a cooler temperature in just a few specific rooms. By circulating the cool liquid in the collector loop (in the drill hole, ground or lake), cool air is created at a cost equivalent to the energy consumption of a couple of light bulbs.
The Cooling Module Passive is included as standard in Comfort. All other heat pumps are compatible with the Module, except for pumps in the Atria series.
