Essential HVAC Guide – Air Conditioning Control Systems
People often talk about getting some form of temperature control included with their reverse cycle ducted air conditioning system. So what are the different forms of air conditioning temperature control and how do they work? We will look at the common types of air conditioning temperature control systems and how they work below.
Basic Air Conditioning Controller
The basic controller that comes with your reverse cycle air conditioning system comes with a thermostat that reads the air conditioners temperature. Usually this temperature is read either from the controller itself or more commonly inside the return air box of the unit that sits inside the roof space.
If the temperature is read inside the return air box, it is sometimes not an accurate representation of the temperature in the room. The room itself may be quite cold but by the time the air is recirculated to the return air box it may have warmed up significantly which means the air conditioner will keep running (e.g. the controller in the living room is set to 22 degrees but once the air reaches the return air box it has heated back up to 30 degrees, which in turn causes the air conditioner to keep running).
