Please install and connect the controllers according to
local rules and standards!
WARNING Please note that in the following cases there is a danger
at hot water tabs (kitchen, bath). In order to avoid
scalding please mix enough cold water.
Anti legionella automatic
If the anti legionella automatic is activated, the domestic
hot water will automatically be heated up to temperatures
around 65 °C order to kill legionella bacteria in the hot
water system.
Manual operation / Emission measurement
In the manual mode / emission measurement mode the
domestic hot water can be heated up to the maximum
possible boiler temperature because the burner and all
pumps are switched on and the valves will be completely
opened. In addition, here there is the danger of scalding
at all warm water tabs in the building. Please mix enough
cold water or switch the domestic hot water loading
pump manually off (if there is a switch at the pump).
Heating and domestic hot water are not temperature
controlled in these modes. These modes are especially
used by the emission measurement specialist or by the
installer in case the controller is defect. The high water
temperatures can however be avoided if the boiler
thermostat is adjusted to a max. of 60 °C.
CAUTION According to VDE 0730 the power supply for the
controller must have a separate main switch for life and
neutral. Please follow local rules and standards for
cabinet earth and ground!
As soon as there is power supply at the terminals 21, 22,
2, 6, 12 and 18, also the terminal rows X3 and X4 will
carry 230 V connections!
