The remote control is not included in the boilers standard supply package and is purchased separately
if desired by the customer. The cable for connecting the remote control to the boiler is not included in
the remote control's supply package and is purchased separately. The standard cable consists of a
connector for connecting the remote control to the electronic board, two wires 1 meter long and a
terminal strip for connecting the wires. If the cable is long enough, it is necessary to disconnect the
terminal strip and connect the cable wires to the remote control (see the instructions for the remote
control). If a connection wires' length of more than 1 meter is required, it is necessary to connect two
additional wires of required length to the terminal strip, herewith the wires must be convolved like a
twisted pair wire. The main requirements for choosing wires are: flexible copper multiple-core cable
with cross sectional area of 0,5...1,5 mm
cable).
10.3.3. Connection of external temperature sensor
It is recommended to use an external (street) temperature sensor of the TPEB type. The sensor is
connected to the terminal strip of the room thermostat's connector (installed into the connector M10),
see Annex III, page 53). It is necessary to control that the plug wire is installed in the room
thermostat's connector on the contacts 28 and 29. In case of connecting the remote control together
with the external sensor to the boiler it is necessary to remove the plug wire from the contacts 28 and
29 in the room thermostat's connector and give it to the boiler's owner so that he keeps it.
The cable for connecting the external sensor to the boiler is not included into the sensor's supply
package. The main requirements for choosing the cable are similar to the requirements listed in p.
10.3.1. The connecting instruction of the sensor is supplied together with it.
10.3.4. Connection of a computer for diagnostics
The electronic board provides a possibility of connecting a stationary or portable computer for boiler
operation parameters diagnostics to the M7 connector (see Annex III, page 53). For this a special
program and an adaptor for connecting the electronic board with the computer is needed (presence of
COM port on the computer is necessary).
10.3.5. Connection of several room thermostats
The electronic board provides a possibility of connecting several room thermostats additionally,
located in different rooms of the house or flat, to the connector M8 (see Annex III, page 53) through
the contacts 38 and 39 of the electronic board. For this a special zone control electronic board is used
(not included into the standard supply package). The instruction and cable for connecting the zone
control electronic board are supplied together with it.
10.4. Switching the boiler off
It is necessary to switch the boiler off before starting reparation works or maintenance service. It is
recommended to switch the boiler off in the following sequence:
1) To render the boiler to standby mode, consequently pressing the button K5;
2) To disconnect the power cable plug from the AC outlet of the power line;
3) To close gas and water taps.
10.5. Water drain from the boiler's heating circuit
At heating circuit's elements dismantling it is necessary to drain the water from the boiler. For this
it is necessary to twist off the drain valve 13 (see p. 13.1 page 24).
In case of long-term idleness of the boiler in winter time or in case of pipeline freezing
danger appearance it is necessary to drain the water from the boiler and the heating system.
