Operation and maintenance
Before starting, check that the installation is in a fully
satisfactory condition.
Ask the installation engineer to demonstrate the control
and functions so that you know how the system works
and must be maintained.
Check that the boiler and heating system are filled with
water, vented and that the pressure is correct.
That all necessary valves are open.
That any safety valves are working.
That any external safety equipment is working as
intended.
That the circulation pump is working and the flow
direction is correct.
For configuration, see "Menu - Management".

11. Indicators, display and configuration buttons.
14. Control switch, two-pole
16-18. Reset overheating protection.
Start
1. Set the main/control switches to the on position,
the display lights up along with a green indicator.
2. Set the desired boiler temperature.
3. Because the boiler has been without power, only three
output stages are stepped in. The remaining output is
connected after one hour if necessary.
For testing and service, the delay can be temporarily
disconnected by changing row 2 of the installation/service
level to 1.
4. The boiler should now step in the number of output stages
needed until the temperature conforms to the set value.
The step in times can be reduced by changing row 1 in the
installation/service level to 1. Fast stepping is deactivated
automatically after 15 minutes.
Activation delay
According to the recommendations, a maximum of 50% of
the output should be connected immediately after a voltage
loss. The remaining output comes in after one hour. The delay
can be permanently disconnected by changing row 14 in the
advanced service level to 1.
Load guard
The load guard protects the main fuses against overload
by reducing the boiler's output. When the overload ceases,
the output is reconnected stage by stage.
See the menu item "Service Level" rows 3 and 4.
Safety valve
To maintain the safety function, safety valves in the heating
system must be operated regularly, about 4 times a year.
Venting - water pressure
Regularly check that the water pressure is correct. Air may
be left in the system for a while after installation, for which
reason it should be vented a few more times.
The pressure in a heating system varies with the
temperature. Do not add water unnecessarily!
Draining
If the heating system needs to be drained of water, the boiler
must first be switched off so that the immersion heaters are
not damaged.
Overheating protection
The boiler’s overheating protection is triggered if the
temperature exceeds approximately 100°C. The protection is
reset behind the reset plug on the front panel. Resetting can
be done when the temperature falls below 80°C.
Always check the cause of a guard being
triggered!
If the guards are triggered repeatedly,
the cause must be remedied!
