The hydraulic connection can be made either with system pipes from the wall or from the floor. install the suitable unit shut-off valves. Proceed as follows:

1. Remove the protective caps from the
2. Connect the system piping to the G1/2″ female

The product does not have a pressure relief valve. it is therefore good installation practice to provide such a device. All pipes must be insulated with insulation not less than 9 mm thick. Also insulate the fittings and hoses connecting the valves and the radiator front panel for about 15 cm on the valve side. The insulating sheath must be fixed and closed with tape without leaving empty spaces.

Using a “Y” filter

it is advisable to use a Y filter on the unit delivery to prevent any impurities in the circuit from entering and depositing inside the heat exchanger. Be sure to install the filter opening and purging system facing down. To ensure easy maintenance and cleaning of the filter, it is advisable to install a check valve downstream the filter and a closing valve upstream

Condensate drain connection

The condensate drainage system must be installed with a suitable slope to ensure the correct flow of condensate to the drain.

Electrical connection

Before making the electrical connection, make sure that the appliance rated voltage (230 V AC 50 Hz) is equal to the mains voltage, and that the socket is able to provide the rated current corresponding to the maximum power of the model selected. Moreover, such socket must be controlled through a double-pole switch used to switch the radiator on and off.

The product can:

1. Be managed by a control thermostat (user interface) installed on board and work as a master in a wired master-slave connection. in turn, the thermostat can be with and without Wi-Fi connectivity;
2. Work as a slave in a wired master-slave connection and thus delegating control to its master;
3. Be managed by a control thermostat (user interface) installed on board and work as a standalone. in turn, the thermostat can be with and without Wi-Fi connectivity.

For each of the three scenarios, the relevant wiring diagrams are given at the end of this manual. After making all electrical connections and positioning the power PCB cover back in place, seal all lower and upper cable passages using the adhesive patches provided, as shown in the figure below.
