Thermomanometer
The current heating water temperature is displayed in the top half. The water
pressure in the heating system is displayed in the lower half. In normal use, the
water pressure should be between 2.0 - 2.5 bar.
In summer mode, the circulation pump operates for approx. 30 seconds after a
maximum idle period of 24 hours.

pump protection
Note:
The number of times the gas boiler can be started in heating mode is limited
electronically. This limit can be bypassed by pressing the reset button. Then, the
equipment starts immediately, as soon as a heating demand is present.
Emissions test mode
The emissions test mode is activated by rotating the heating water temperature
selector into position . The illuminated ring flashes yellow. After the emissions
test mode has been activated, the boiler will heat to the selected maximum hea
-
ting output. Any previous cycle block will be cancelled. The emissions test mode
terminates after 15 minutes or when the maximum flow temperature has been
exceeded. For a renewed activation, turn the heating water temperature selector
anti-clockwise and then back into position
.
Summer mode
Winter mode is deactivated by rotating the heating water temperature selector
into position
. In other words, the equipment will then operate in summer
mode. Summer mode (central heating OFF) means = only DHW heating. Frost
protection for the central heating system and pump anti-seizing protection are,
however, assured.
Winter mode (position 2 to 8)
In winter mode, the boiler heats to the temperature selected at the heating water
thermostat. According to the pump operating mode, the circulation pump opera
-
tes constantly (factory setting) or only in parallel with the burner activation/run-on
time.
