9 Tips for Installing a Humidistat in Your Home

A humidistat is used to control the level of humidity in your home. It is used in congruence with air conditioners, dehumidifiers, and humidifiers. There are specific specifications for installing a humidistat in your home.

Location, Location

Be sure to check your manufacturer’s instructions. You’ll want to place the humidistat in just the right position. After determining where the unit should go, make an outline of the item before cutting the hole.

Power Out

Manufacturers recommend turning off power before making any wire connections, including installing the humidistat. If your particular model calls for a step-down transformer and you’ve got to run wiring for it, be sure to shut the power off before installing the transformer.

Check Local Codes

Local codes might allow for tapping water lines for installation of saddle valves. However, some codes might not allow for saddle valves. In that case, you’ll install a T-fitting.

Check Manufacturer Recommendations

To settle on which settings are best for your area, you should check with your manufacturer. You’ll incur higher energy costs if they are set incorrectly and running too much.

Setting Your Humidistat

You’ll need to set your humidistat with temperature changes; that way your indoor humidity levels remain steady.

If your humidistat is programmed incorrectly, there will be signs. Condensation on places like walls, windows and doors is one sign. Cracking wood floors are another and an indication that the unit is too low. Puddles on the windowsill indicate that it is set too high.

If you set your humidistat below 60 percent humidity level, it will cause your home to be far too cold. There is no need for it to be lower than 65.

No Change in Humidity?

If you install the humidistat and you find that there is no change in the humidity in your home, the problem might not be with your device but with your humidifier. However, if the humidifier simply isn’t reacting to the commands it is receiving from your humidistat, the latter might be broken. You’ll need to call in a professional before any damage is caused.

Testing, Testing

If you experience problems with your humidistat, you can use a volt-ohm meter to check it. Test it with the meter set to the RX-1 scale by attaching it to the terminals on the unit. If the meter doesn’t jump as you turn the humidistat from high to low, you’ll need a replacement.

Don’t Get Duped

If you’ve had a humidifier professionally installed, make sure the installer has finished the job. If you find the wires for the connection to a humidistat on your new humidifier but no humidistat, call the installer and have them come back to complete their work. There’s no need to do it yourself if it’s a job unfinished by a “handy” man.

Don’t Forget

After installation, be sure to oversee one cycle of operation to make sure that all components are running properly.
