The controller is designed for cascade control of heating, air conditioning and other installations built with more than one unit.
In heating or cooling mode, the controller monitors the measured and set temperature and, according to the set parameters, turns on or off a certain number of units to maintain the set temperature.

For a uniform load, it is planned to change the order of turning on and off the stages according to “FIFO” logic.
