5.4.4 Additional heat generator
Function (ECO-KP1):
The additional heat generator is automatically connected
when required. This takes place after the system tempera-
ture is fallen short of that is set for covering the entire
heat requirement or a peak in heat requirement. A boiler
plant group is required to carry off heat for the additional
boiler that will simultaneously provide for maintaining the
return flow.
Operating modes:
- Off:
The additional heat generator is switched off.
- Automatic:
Automatic clearance of the additional heat generator
when either an adjustable connecting temperature for
the accumulator is fallen short of or a sensor for the
forward flow bar.
- On:
Additional heat generator cleared.
- Manual:
Additional heat generator cleared and pump on; the
valve is not controlled (emergency operation).

(02) Delay before connecting (15 min)
Clearance is given when the time set is up.
(03) Connecting temperature, system set-point tempera-
ture (-15°C)
If the system temperature falls by this amount below the
system set-point temperature, the delay before connecting
(screen 2) begins to lapse.

ture (-5°C)
Switch-off difference in parallel operation

(10) Load storage unit to (70°C):
To what temperature on the accumulator sensor selected
should the additional heat generator heat up the accumula-
tor?
