boiler" [ 194]. Static pressure MUST be 20 mbar (+ or – 1 mbar). If the
working pressure is <19 mbar, the gas boiler output will be reduced and the
correct combustion reading may NOT be obtained. Do NOT adjust the air and/
or gas ratio. To obtain sufficient working pressure, gas supply MUST be
correct.
INFORMATION
Make sure the working inlet pressure does NOT interfere with other gas appliances
installed.
The gas boiler has a test run function. Activating this function results in the
activation of the gas boiler (pump starts and fan starts with a fixed speed), without
the control functions being actuated. The safety functions remain active. The test
run can be stopped by pressing
after 10 minutes. To perform a test run, switch off the system with the user
interface.
Make sure that the leaving water temperature home page, room temperature
home page, and domestic hot water home page are turned OFF.
There may be no error on the gas boiler or the heat pump module. During a gas
boiler test run, "busy" will be displayed on the user interface.
