Connecting The Mains Supply; Fitting A Room Thermostat; Connecting A Programming Clock - Chappee initia MASTER 2.24 FF Installers And Users Instructions

Connecting the mains supply
Electrical safety of the appliance is only guaranteed by correct grounding, in compliance
with the applicable laws and regulations.
Connect the boiler to a 220-230V monophase + ground power supply by means of the
three-pin cable supplied with it and make sure you connect polarities correctly.
Use a double-pole switch with a contact separation of at least 3mm in both po-
les.
In case you replace the power supply cable fit a HAR H05 VV-F' 3x0.75mm
an 8mm diameter max.
...access to the power supply terminal block
• isolate the electrical supply to the boiler by the double-pole switch;
• unscrew the two screws securing the control board to the boiler;
• rotate the control board;
• unscrew the lid and gain access to the wiring (Figure 10).
A 2A fast-blowing fuse is incorporated in the power supply terminal block (to check or
replace the fuse, pull out the black fuse carrier).

Fitting a room thermostat
• gain access to the power supply terminal block (Figure 11) as described in the previous
section;
• remove the jumper placed on terminals (1) and (2);
• insert the duplex cable through the core hitch and connect it to the two terminals.
Connecting a programming clock
* connect the programming clock motor to the main PCB CN1 connector (terminals
1 and 2);
* connect the programming clock switch to the CN1 connector terminals (3 and 4) and
remove the jumper.
In case you are fitting a battery-operated programming clock do not connect the CN1
connector terminals (1 and 2).
