This model is designed exclusively for 240 volt fan coil systems.
It allows a low voltage WIFI thermostat to communicate with 2 or 4 pipe fan coil systems that have high voltage with up to 3 fan speeds and offers additional relay options for better indoor air quality.
The addition of ultraviolet lights or Bi-Polar Ionization is an efficient method to kill bacteria, viruses, mold, and other allergens in the air and can significantly reduce allergies and asthma symptoms.
Adding humidification can also help with allergies as well as with dry skin, respiratory symptoms, or irritated eyes.
This universal board is easy to install simply wire your fan coil and thermostat to the board.
