IO HVAC Controls TWIN Universal Twinning Kit

The IO HVAC Controls TWIN Universal Twinning Kit allows two HVAC systems to be operated as one and helps in achieving the twin objectives of efficiency and coordination. This is a single-stage gas furnace, air conditioner, or air handler control that can operate several units at a go. It achieves this by connecting the control boards of the two units so that they run in parallel with the fans and temperature regulated in equal measures. It is suitable for residential or light commercial applications, it does not require the installation of other thermostats to make the system reliable.
