DHW heating
The DHW heating is used for demanding a backup heating for heating the DHW
store.
For the DHW heating, 2 different modes are available:
Thermal mode
The allocated demand relay is switched on when the temperature at the allocated
sensor 1 falls below the adjusted switch-on temperature. If the temperature at the al-
located sensor exceeds the adjusted switch-off temperature, the relay is switched off.
Zone mode
If the Zone mode is selected, the switch-on and switch-off conditions must be
fulfilled at 2 sensors for the relay to switch on or off respectively.
If the Load. temp. option is activated, the actuator of the transmission station
controls the outlet temperature at the secondary side to Toff +
D TFlow.
When the Timer option is activated, a timer is indicated in which time frames for
the function can be adjusted.
Note:
For information on timer adjustment see page 10.
