ATTENTION

Hot water maximum temperature limit is a function protecting the tank and terminates hot water loading. If overshooting occurs, the tank loading pump switches off immediately. In this case it cannot be ensured that the set extended running time is adhered to.

NOTE If a hot-water circuit thermostat is used instead of an electronic sensor, the hot water maximum temperature setting (plus the specified temperature shift during loading) is forwarded to the heat generator.

Control mode With this function it is set how the rest of the heating system reacts to heat demand from the hot-water tank. There are 5 different setting options.

Parallel operation

During hot-water circuit loading, the heating circuits remain operative.

Priority mode

During hot-water loading, the heating circuits are put out of operation. They are restarted as soon as the hot-water circuit loading pump extended running time is over.

If the hot-water setpoint temperature is not reached after 4 hours, a fault message is indicated on the display.

Conditional priority

If the temperature of the heat generator has exceeded the loading temperature for the hot-water tank, mixed heating circuits are enabled. Non-mixed heating circuits (DHCP) remain disabled during hot-water circuit loading. The heating circuits are enabled according to the following criteria:

Enabling the heating circuits:

Heat generator actual temperature > hot-water setpoint temperature + hot-water switching differential/2 + 10 K

Disabling the heating circuits:

Heat generator actual temperature < hot-water setpoint temperature + hot-water switching differential/2 + 5 K
