DHW heating
The
DHW heating
is used to demand an afterheat-
ing 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
option is activated, another adjust-
ment channel appears, in which the overrun time can
be adjusted. If the overrun time option is activated,
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 fulfi lled at both sensors in order for the relay to
be switched on or off.
When the
Timer
option is activated, a timer is in-
dicated in which time frames for the function can be
adjusted.
Note:
For information on timer adjustment see
page 11.
