Starting the boiler up
Important:
Putting the boiler into operati-
on and starting it up for the fi rst time must
be done by an authorised service only!
If you wish to start the boiler after it has
been put into operation, make sure that:
1. the boiler is connected to power supply;
2.
all valves underneath the boiler (hot
water, heating water, gas) are opened;
3. the heating water pressure is within the
recommended range 1,2 – 2 bar.
Turn the main switch (Fig. 1, pos. 1) ON.
A few moments later the heating water
temperature will appear on the display and
the LED under the symbol
will light up
(Fig. 1, pos. 2). When the burner ignites,
the LED under the symbol
will light up
(Fig.1, pos. 6).
In the event of an emergency boiler
shutdown, a fault indicating red LED will
light up on the control panel
(Fig. 1,
Position 5) and an error message code
will appear on the boiler’s display. Unblock
the boiler by pressing the RESET button
(Fig.1, Position 9). If the emergency
shutdown recurs after a short time again,
or if the boiler cannot be RESET, call an
authorised service organisation.
Turning the boiler off
Turn the main switch (Fig. 1, pos. 1) off.
If the boiler is to remain shut down for a
protracted period of time, shut all valves
underneath the boiler off (HeW, HoW, gas).
When shutting the boiler down, take into
consideration the ambient temperature in
the given season. If there is a danger that
the boiler may freeze, drain the water from
the boiler, the heating system and the hot
water pipes.
Starting the boiler up and turning it off
Boiler control
Using the boiler without room
control unit
When run in this mode, the boiler maintains
the set heating water temperature. No room
control unit is connected, the terminals for
its connection must be interconnected
with a jumper (standard factory setting).
Setting procedure:
• turn the main switch ON;
• set the heating water temperature to the
required value on the control panel.
Using the boiler with room control
unit
The boiler maintains the set heating
water temperature. The room control
unit connection terminal jumper must be
removed and the room control unit wired
to the terminals. The boiler is turned on
and off to maintained the set temperature
in the room in which the control unit is
installed. Radiators in this room must not
be equipped with thermostatic valves.
Important:
You must set on the boiler
control panel a heating water temperature
(temperature of the water in the system)
which will be capable of covering thermal
losses of the building even in low outdoor
temperatures.
Please note:
Use only control units
recommended and sold by PROTHERM
which are designed and tested for the
particular type of boiler. If you use a
different unit, we cannot guarantee the
boiler’s correct and full functioning.
