Two- or three-way ON/OFF valves already wired and installed inside the indoor unit. The connection to the system is made with hoses located on the rear of the unit. Without any increase in dimensions or complications in installation, the valve closes on reaching the set point, recirculating the flow of water and preventing it from entering the heat exchanger.

Supplied as a standard feature, the infrared controller can be used to control a single indoor unit or a combined network and to program daily time slots.

The true strong point of this controller is tied to the development of communication networks. By connecting up to 32 units via a network bus and connecting the WALLPAD controller to one of them (Master) it is possible to control their operation. In particular, the user can choose whether to communicate simultaneously with all of the connected units, for example to change the operating mode of the entire system, or dialogue with each individual unit, differentiating the settings between one fan coil and another. The selection of “global” communication or communication with a single indoor unit is made by simply pressing a button.
