Scheme 10. Circulation pump check
Than screw the cover plug up tight. While effecting this operation water leaks from the pump are possible, after
installing the cover plug the rests of water must be removed from the boilers components (you must wipe them);also
check the boiler connection to the AC outlet of the monophase network of alternate current with rated voltage of
220V, 50Hz frequency, with an earthbonding contact;
10)
Also check the heating system’s airtightness.
CAUTION! Water getting onto the boilers electronic components is unacceptable!
10.2.Check of combustion properties
The boiler permit to effect the heating-performance parameters analysis not disturbing the boiler’s
settings. For this it is necessary to use the function of gas analysis (measuring of output gases
temperature and of the content of carbonic oxide in them). Before activating this function (see
p.13.2.2, page 27) it is necessary to make sure that the boiler is switched on and operates in the
heating mode or in the combined mode, and the smoke exhauster pipe has an orifice for the gas sensor
input on the straight section on a distance of not less than 250mm from the gas removal device outlet.
During the combustion process analysis the water overheating protection system remains active, when
the water reaches the temperature of 88
o
C the boiler will pass to standby mode. After finishing the
measurements the gas sensor inlet orifice must be made airtight.
10.3. Additional abilities (options)
10.3.1. Connection of room thermostat
For more effective operation of the boiler it has a possibility to connect a room thermostat, that is
installed in the heated premise. In order to install the thermostat it is necessary to remove the plug
wire from the contacts 28 and 29 (connector M10) from the room thermostat’s connector (see Annex
III, page 53) and place the cables with a terminal strip from the contacts 26 and 27 to the contacts 28
and 29. Then you must effect the connection of interconnecting wires of the room thermostat to the
terminal strip (the thermostat’s wires’ connection polarity does not matter). The plug wire must be
given to the boiler’s owner so that he keeps it.
The room thermostat is not included in the standard supply package and is purchased separately if
desired by the customer. The cable for connecting the room thermostat to the boiler is not included
into the thermostat’s supply package. The main requirements for choosing the cable are: the cable’s
maximum length is 30 meters, it consists of two wires (flexible copper multiple-core cable with cross
sectional area of 0,5…1,5 mm
2
).
10.3.2. Remote control connection
The boiler permits to use a remote-control console (hereinafter referred to as “remote control”). The
remote control has got an inbuilt temperature sensor and permits to control the boiler from a distance
(not more than 30 meters from the boiler) and set the same commands as from the control panel. Also
the remote control permits to control the boiler’s operation, keeping the temperature set by the user in
the premise. The remote control is connected to the connector M8 through the contacts 40 and 41 of
the electronic board (see Annex III, page 52). While connecting the remote control it is necessary to
remove the room thermostat’s connector from the M10 connector and give it to the boiler’s owner so
that he keeps it (see p.10.3.1).
It is acceptable to connect the remote control together with the external (street) temperature sensor
(see p. 10.3.3). Herewith the boiler regulates the temperature in the heating circuit either with the help
of the remote control’s temperature sensor, or depending on external temperature (see p. 3.3.3, page
9). The remote control can display the street temperature value.
Before connecting the remote control it is necessary to make sure that it is prepared for putting it into
operation in accordance with the installation and connection manuals that are included in the remote
control’s supply package.
