HVAC FCU controller

This module has 6 relays to control multiple fan speeds (low, medium, high), cooling, heating, and auxiliary contact. Keep in mind that the auxiliary contact can be configured for both a dehumidifier and/or heating/cooling pump. These secondary switching devices can perform a second cooling/heating stage. For example, a two-stage AC offers two levels: high and low. It runs at full capacity when you need it to and at a lower level when you don't. (The HVAC Module makes the AC work at its highest speed on hot summer days and at the lower speed on mild spring days).

The HVAC Module is also equipped with an external temperature sensor that helps when it’s working with other wall thermostats such as the Luna panel. It can function as a stand-alone room heating calculator as well (it shows the average temperature in a room). This means that the HVAC Module installed in your bedroom can be linked to the Luna panel in the living room. As the result, both rooms are warmed based on their scale, and no one is overheated.
