4. Operating instructions
4 Operating instructions
4.1 Start the boiler
` Check the water pressure in the installation several times a
year.
If necessary, top up the boiler with water.
The water pressure in the installation must be between 1.5 and
2 bar.
` Open the gas valve.
` Set the 6-position switch T to  (summer mode) or "
(winter mode).
` If using a room temperature thermostat or a communicating
remote control, turn them to heating request.
`
` The boiler will begin an automatic venting-programme (which
lasts approx. 3 minutes) and will do this every time the power
supply is isolated.
` The regulator starts an initialisation phase during which the LED
flashes red and green. When initialisation is complete, the
regulator changes to automatic mode. The factory settings for
this mode give optimum performance with most installations.
