What Exactly Controls My Air Conditioning Unit?

When you have both a thermostat and a humidistat, it can be difficult to figure out what exactly controls your air conditioning. For example, let’s say you just recently replaced your air conditioner and the new controls will only run the if your air conditioning unit both the temperature and the humidity settings are exceeded. What should you do?

The most common configuration of thermostat and humidistat for controlling air conditioners involves the two working separate controls. The air conditioner turns on if the conditions in the home meet the set points for either the thermostat (i.e. 88 degrees F) or the humidistat (58% relative humidity). You can easily check if you have this type of configuration by:

First, check if temperature alone turns on air conditioner. Set the humidistat to the highest relative humidity requirement (largest RH %) and then set the thermostat cooling setting to the lowest temperature. If the air conditioner turns on after a few minutes, it confirms that the thermostat can control it independently.

Furthermore, check if relative humidity alone turns on the air conditioner. Set the thermostat cooling setting to the highest temperature, and then set the humidistat to the Continue reading
