Handling the heating installation
the heaters switch off, and the warning code shifts to
error code.
7.4
Putting the boiler out of operation
- E1 for operating pressure below 0.5 bar
- E2 for operating pressure above 2.5 bar.
WARNING:
Material damages caused by
freezing!
In order to keep the boiler working, it is necessary to
bring pressure within the normal value limits. Image 19.
Warnings related to temperature
If the heating installation is out of operation, it could
freeze at low temperatures.
Protect the heating installation from freezing.
Empty the installation if there is a risk of freezing
-
When the temperature in the system is less than 5°C or
higher than 80°C, the current value of temperature
starts to flash, and a warning triangle is displayed that
continuously flashes as well as warning codes (Image
20).
and if the boiler is out of operation.
When the device is put out of operation for a long
time, the pump of heating can be blocked.
To
remove the blockage, it is necessary to act as in the
case of discharging of air (
chapter 4.6.2).
Place the main switch on the control panel in position “0”
(switched off).
Protect the heating installation from freezing.
Empty all lines completely.

Warnings related to temperature
- A3 for temperature below 5
°C
- A4 for temperature above 80
°C
If the temperature drops below 3
°C, the heaters and the
pump switch off, and the warning code shifts into the
error code:
- E3 for temperature below 3
°C
The heaters will switch off if the temperature rises above 85
°C,
and the pump works regardless of the room thermostat, and the
warning code shifts to error code:
- E4 for temperature above 85
°C.
To keep the boiler working, the condition is that the temperature
returns to normal values.
7.3.1
Regulator
of room temperature
If the regulator of room temperature is used, it must be
installed in the reference room. Control of the temperature
of all rooms by the heating system is
carried out by this remote control.
Radiators in the reference room should not be equipped with
thermostatic valves, or they must always be open. All radiators in
other rooms can be equipped with thermostatic valves.
7.3.2
Cease of heating
The temperature of the boiler must be lowered in the short-term
cease of heating by using
boiler’s thermostatic regulator.
To prevent the freezing of the heating installation,
the temperature
Of the boiler must not be set below 5
˚C. The boiler must be put out of
operation in case of longer cease of heating (
chapter 7.4).
