Connecting the room thermostat and the hot water on/off function
Use a 4-core 0.75 mm² insulated cable for the connection of the room thermostat (with the hot water
on/off function). Connect the room thermostat as follows:
Remove the right-hand plug behind the dashboard (see fig 12);
Remove the cover from the plug;
Connect the room thermostat wires to T1 and T2 as shown on the sticker on the plug (see fig
11);
Connect the wires for the hot water on/off function to points S3 and B4 as shown on the
sticker on the plug (frostguard) (see fig 11);
The two boiler thermostat wires only need to be connected to points L1 and N (see fig 11) with
the Compact 7 boiler;
Remove the front of the room thermostat;
Connect the wires in the thermostat to Q14 and Q11 (see fig 10);
Connect the hot water on/off function to points Q21 and Q22 in the thermostat (see fig 10);
If the tap is visible in the display hot water is switched on. If not it is switched off.
