6.4.6 Additional heat generator
Function (ECO-KP1):
The additional heat generator is automatically
connected when required. This takes place after
the system temperature 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 connect-
ing 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 op-
eration).

(02) Delay before connecting (15 min)
Clearance is given when the time set is up.
(03) Connecting temperature, system set-point
temperature (-15°C)
If the system temperature falls by this amount be-
low the system set-point temperature, the delay
before connecting (Mask 2) begins to lapse.
(04) Switch-off temperature for system set-
point temperature (-5°C)
Switch-off difference in parallel operation
(07) Set-point temperature of return flow
(50°C)
Desired temperature of return flow
(09) Load storage unit to (storage unit at top):
To which heat storage sensor should the storage
unit be loaded?
(Indication only with accumulator option)
(10) Load storage unit to (70°C):
To what temperature on the accumulator sensor
selected should the additional heat generator heat
up the accumulator?
(Indication only with accumulator option)
