Electrical Connections And Controls; Installing The External Thermostat - Piazzetta P963 Instructions For Installation, Use And Maintenance Manual

5.2 ELECTRICAL CONNECTIONS AND CONTROLS

Power cable (6)
• The stove/fi replace comes with a power cable which must be
connected to a 230V/50Hz mains socket. Connection to the rear of
the stove/fi replace is shown in fi g. 43.
• The power rating is indicated in the paragraph "TECHNICAL DATA".
a
The appliance must be connected to an effi cient earthing/
grounding system.
Ensure that in its normal position the power cable does not
come into contact with any heated parts.
Ensure that the electrical plug is accessible also after
installation of the stove.
Room sensor connection (5)
• When installing the stove/fi replace, it is necessary to connect the
room sensor (provided) to the correct jack (Fig. 41). The sensor can be
positioned as shown in fi g. 42, otherwise remove the band, uncoil the
lead and then place the sensor in a spot where a more accurate room
temperature reading can be obtained.
Pipe tap (3)
• The appliance has an external socket for measuring the pressure
(vacuum) of the fl ue gas outlet pipe. This control and verifi cation should
be carried out by authorised personnel at the time of installation or
during maintenance.
Connection to the DB9 serial socket (7)
• The appliance has a DB9 serial socket, which is used to check
appliance operation. Controls should be carried out by authorised
personnel at the time of installation or during maintenance.
• The optional GPRS kit, if ordered, may be connected to the DB9 serial
socket.

5.3 INSTALLING THE EXTERNAL THERMOSTAT

The appliance is designed for connection to an external room thermostat
(not included in the package).
To connect the thermostat use a 2x0.5 mm
cable gland to be inserted in the relative hole in the rear panel (Fig. 46).
Only authorised personnel should carry out this operation.
a
Installation can be carried out with any type of room thermostat
but requires a PG7 cable gland similar to that shown in fi g. 45.
To connect the room thermostat to the electronic board, refer
to the wiring diagram.
Proceed as follows for installation:
- disconnect from the main power supply before opening the appliance;
- remove the protective panel from the electronic board and then
remove the rear panel (Fig. 44);
- remove the knockout to be found in the rear panel (position 4 – Fig.
41);
- insert the thermostat cable through the PG7 gland and then insert the
gland into the hole obtained from removing the knockout in the rear
panel (Fig. 46);
- connect the room thermostat cable terminal to the 2-pin terminal of
the electronic board (detail Fig. 44 – see WIRING DIAGRAM);
- refi t the rear panel, ensuring that the cable inside the stove cannot
come into contact with hot or moving parts;
- refi t the protective panel over the electronic board.
