Safety instructions

Local regulations on the connection of equipment must be 
observed! 

 

 

When the automatic anti-legionella mechanism is activated, the 
hot water is automatically heated to the anti-legionella 
temperature (65 °C at the factory) on the selected day and at the 
selected time to kill any legionella bacteria found in the hot-water 
tank. 

 

In the manual mode / emission measurement operating mode, the 
hot water is heated up to the highest possible boiler temperature, 
as the burner and all pumps are switched on and the mixer is 
opened fully. There is an acute danger of scalding at all 
connected hot-water draw-off points! Add sufficient cold water or 
switch off the hot-water loading pump (at the switch of the pump, 
if present). Heating and hot water are in unregulated continuous 
operation. This operating mode is for special use by the chimney 
sweep for emission measurement or if the controller is defective. 
The high hot-water temperatures can be prevented, however, by 
setting the boiler thermostat to a max. boiler temperature of 
approx. 60 °C.
