The additional heat generator
charges the heating water
buffer tank up to the first
buffer tank temperature
sensor.
Note: Only useful if the
additional heat generator has
its own boiler circuit pump.
The additional heat generator
charges the heating water
buffer tank until the
temperature of 167°F (75°C)
at the selected sensor
(code "D0:1-5") is reached.
Start delay of the additional
heat generator of 10 min
Start temperature of the
additional heat generator.
Starting condition:
Actual system temperature
< set system temperature
minus value set (here: 10 K)
Minimum runtime of the
additional heat generator
of 5 minutes
Minimum pause duration of
the additional heat generator
of 5 minutes
Start of additional heat
generator without delay.
Condition: Actual system
temperature < set system
temperature minus value set
(here: 20 K)
Parallel operation of both
heat generators is possible.
Note: Parallel operation only
possible when the additional
heat generator
has a boiler circuit pump.
Possible change
D0:0 The heating water buffer tank
temperatures are ignored.
D0:2 The additional heat generator charges
the heating water buffer tank up to the
second buffer tank temperature sensor.
D0:3 The additional heat generator charges
the heating water buffer tank up to the
third buffer tank temperature sensor.
D0:4 The additional heat generator charges
the heating water buffer tank up to the
fourth buffer tank temperature sensor.
D0:5 The additional heat generator charges
the heating water buffer tank up to the
fifth buffer tank temperature sensor.
