Humidification / Dehumidification

What is the ideal humidity percentage to maintain?

The ideal humidity range for a typical home is 40% - 60%.

Humidity levels over 60% can cause or worsen health issues such allergies and asthma.  Fungi, bacteria, mites and viruses all thrive in humid environments.  Fungal growth, caused by high humidity levels, can also cause damage to your home.  You can find more information on ways to manage high humidity in our blog.

Bacteria and viruses also thrive in climates with humidity below 40%.  This can increase the risk of respiratory infections and other conditions during cold and flu seasons.  You can find more information on ways to fight dry winter air in our blog.

I have a Y2* wire on my current Sensi. How do I know if I have two stages of cooling or humidification?

The easiest way to determine if you have a two-stage unit is to consult the manufacturer’s manual for your system.  Some consumers have two separate AC units acting as two stages of cooling but can easily be determined by checking for two units.

If you do not have two stages of cooling but have a wire located in the Y2* terminal on your Sensi, then you could have a humidifier. Humidifiers are located at or on your system as an extra piece of equipment. If you cannot locate a humidifier, trace the thermostat wires back to the system.  you should see the corresponding Y2* wire connected to the humidifier.

I have a W2* wire on my current Sensi. How do I know if I have two stage of heat or dehumidification?

Two-stage heating systems are not commonly found in high humidity environments; however, it’s still important to verify whether your system is two-stage.  The easiest way to determine if you have a two-stage unit is to consult the manufacturer’s manual for your system. 

If you do not have a two-stage system, trace the thermostat wires to the control panel located at your indoor system, and look for a terminal labeled “Dehum”.  If the W2* wire from the thermostat is connected to a “Dehum” terminal, then you have dehumidification capabilities.
