How do set points work?
​
~ There are 3 modes which allow a temperature set point to be made, cooling mode, heating mode and automatic mode.
~ Set points work relative to the room temperature. The heating and air conditioning system works to bring the room temperature to the set point temperature.
~ For example, if your room temperature is 24 C, and the set point is 21 C, then the heat pump equipment will work to cool the room to that set point. Some controllers have one setpoint, and others have two: a heating set point, and a cooling set point.
~ For a heating set point, the air conditioning system will heat the room to the setpoint temperature and try to maintain that temperature.
For a cooling set point, the heat pump system will cool the room to the setpoint temperature and try to maintain that temperature.
~ If the room temperature is within the two set points, or within the comfort band, the air conditioning system will not heat or cool the space (although it may continue to provide ventilation to your room.)
~ Setting your heat pump lower than 21 C – 22 C in cooling mode is normally regarded as too cold and is generally a waste of electricity in trying to cool the room this cold, likewise trying to heat a room to higher than 24 C is generally a waste of electricity – most people set their home thermostat to approx. 21 C or 22 C so you should set yours to the same temperature.
~ You shouldn’t set the air conditioning system to the lowest cooling setting (generally 16 C – 18 C) – this is far too cold for an office environment and likewise you shouldn’t set the temperature to 30 C in heating mode, both of these simply waste electric.
~ Temperature set points can cause arguments within an office environment; we have found that men generally like the temperature lower compared to women.
~ In summary we would recommend a temperature set point of approx. 22 C.
~ Air Conditioning usually accounts for at least half of a building's energy use, so adjusting setpoints in a building can make a huge difference when it comes to energy savings!
