DHW heating
The DHW heating is used to demand an backup hea-
ting for heating the DHW store.
If the Loading pump option is activated, another
adjustment channel appears, in which a relay can be
allocated to the loading pump. The allocated relay is
switched on and off with the demand relay.
If the Overrun time option is activated, another ad-
justment channel appears, in which the overrun time
can be adjusted. If the overrun time option is activa-
ted, the loading pump relay remains switched on for
the adjusted Duration after the demand relay has
been switched off.
For the DHW heating, 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 allocated sensor 1 exceeds the adjusted switch-off
temperature, the relay is switched off.
Boiler mode:
If the Boiler mode has been selected, another sensor
can be allocated in the channel Sensor 2. The switch-
on, or the switch-off conditions respectively, then have
to be fulfilled at both sensors in order for the relay
to be energized.
When the Timer option is activated, a timer is in-
dicated in which time frames for the function can be
adjusted.
First of all, an overview of the current adjustment is
displayed. For each day of the week there is an over-
view display. The display can be switched back and
forth between the different days by pressing buttons
or 4 .
In order to adjust the timer, press button 5 .
First the individual days of the week or all days of the
week can be selected. The last menu item after the
list of days is Continue. If Continue is selected, the
Edit timer menu opens, in which the time frames
can be adjusted.
The time frames can be adjusted in steps of 15 minu-
tes. The cursor can be moved along the time line by
pressing buttons
or 4 . The beginning of a time
frame can be determined by pressing button 1 . The
end of a time frame can be determined by pressing
button
3 .
