WIRING DIAGRAM FOR REMOTE CONTROL INSTALLATION
(no zone valves)
Fit the interface (fig. 2) on the circuit board (fig. 1) into the holes A and B provided (see fig. 1).
Connect plug M1 on the interface circuit board (fig. 2) to plug M11 on the modulation circuit board (fig. 1).
Connect the grey and orange wires in plug M2 of the interface circuit board (fig. 2) and in the terminal block (fig.
4).
Connect the wires of plug M3 on the interface circuit board (fig. 2) in the terminal (fig. 4).
Remove the link TA-TA (fig. 3) and set the boiler to SUMMER mode.
Connect the remote control to the terminal block (fig. 4) using a cable with a minimum section of 2 x 0.5 mm2
section and max. length of 50 m being careful to observe the +/- polarity.
THE EXTERNAL SENSOR IS OPTIONAL.
The connection can be made to either the remote control (fig. 5) or to
the terminal block (fig. 3 - dotted line) on the terminals marked SE-SE.
WARNING!
The remote control connection cable must pass through a channel which is separate from any system
supplied with power. If this is not possible, fit a screened cable.
