4 Operating the appliance
4.1 Putting the appliance into operation
1. Check the water pressure in the installation shown on the control
panel display.
If the water pressure is lower than 0,8 bar, more water
should be added. If necessary, top up the water level in the
heating system (recommended hydraulic pressure
between 1,5 and 2,0 bar).
2. Open the gas valve on the boiler.
3. Switch on the boiler.
4. The start-up cycle begins and cannot be interrupted. During the
start-up cycle, the display shows the following information:
fK[xx: Software version
pK[xx: Parameter version
The version numbers are displayed alternately.
5. A vent cycle of a duration of around 3 minutes is carried out
automatically.
6. In standby mode, the screen usually displays 0, plus the water
pressure and the symbols d and r.
4.2 Reading out measured values
The following current values can be read off the information menu
Q:
4 5t = State.
4 5v = Sub-status.
4 t1 = Flow temperature (°C).
4 t" = Return temperature (°C).
4 t3 = DHW tank temperature (°C).
4 t4 = Outside temperature (°C).
4 t5 = Solar boiler temperature (°C).
4 t6 = Solar panel temperature (°C).
4 5p = Internal set point (°C).
4 fl = Ionization current (µA).
4 Mf = Fan speed in rpm.
4 pr = Water pressure (bar (MPa)).
4 p; = Supplied relative heat output (%).
