5. Check if the settings of the other parameters (for example the Min.
water pressure and Operational Pressure) are suitable for the
installation and change the settings, if necessary.
8.2.8 Activating the screed drying program
The screed drying program reduces the drying time of a freshly poored
screed floor. Every day at midnight, the temperature setpoint is
recalculated and the number of days is decremented.
1. Select the tile of the zone with the screed floor.
2. Select Set Screed Drying
3. Set the following parameters:
1 Zone screed drying Number of days needed for drying
2 ScreedStartTemp Start temperature of the screed dry
ing program
3 ScreedStopTemp End temperature of the screed dry
ing program
The screed drying program will start and continue for the selected
number of days.
8.3 Start-up
Start the boiler up as follows:
1. Open the boiler gas tap.
2. Turn the boiler on
3. Turn on the boiler using the on/off switch.
4. The boiler will also start an automatic venting cycle lasting around 3
minutes.
5. Check the water pressure of the central heating system shown on the
control panel display. If necessary, top up the central heating system.
The current operating condition of the boiler is shown by the status signal
on the control panel.
8.4 Shutdown
If the central heating is not due to be used for a long period of time, it is
recommended that the boiler be disconnected from the power supply.
1. Turn off the boiler using the on/off switch.
2. Shut off the gas supply.
3. Keep the area frost-free.
8.5
Frost protection
Caution
Tap the boiler and central heating system if you are not going to
use your home or the building for a long time and there is a
chance of frost.
The frost protection does not work if the boiler is out of
operation.
The built-in boiler protection is only activated for the boiler and
not for the system and radiators.
Open the valves of all the radiators connected to the system.
Set the temperature control low, for example to 10°C.
If the temperature of the central heating water in the boiler drops too low,
the built-in boiler protection system is activated. This system works as
follows:
