Water heater @@&name@@
Water heating with anti-legionella switching The enabling has 3 levels:
Anti-legionella switching
The anti-legionella switching can be preset via a building management system switch. There is no anti-legionella operation In the Off position. In the position Auto, it is undertaken once a week or daily on a fixed day at a certain time. The water heater is heated up to the heating temperature of °C. If this temperature is not attained, the anti-legionella operation is completed after the maximum heating duration.
Priority circuit
The priority circuit can be activated via a building management system switch. If this is on Auto, the information 'priority' is set for each turn-on of the water heater, with which, if need be, static heater loops are turned off to favour the storage charge. A maximum duration of the priority circuit can be set to prevent a long shut down by the heater loops influenced by the priority circuit. If the required tap water temperature is not reached after expiry of this time, the information 'priority' is reset, but the water heater continues to operate.
Charging circuit
If the enabling of the water heater (normal mode or legionella mode) takes place, a required charging temperature for a potentially available primary control loop is determined. This is calculated in
If the water heater is inactive, the set point amounts to 20°C.
