Parameters / Function description

KM 27 Set boiler value

and

KM 28 Set boiler value

hysteresis

and

KM 29 Set buffer value

and

KM30 Set buffer value

hysteresis

a) Return temperature raising, wood burning boiler:

The mixer control unit (mixer, return temperature raising and

mixer circuit pump) transfers the energy from the wood burning

boiler into the buffer, and at the same time regulates the return

temperature. The control acts like the mixer circuit control unit;

see also parameter description MI 07.

Mixer circuit pump control:

Mixer circuit pump MKP "ON":

Actual (wood burning) boiler temperature (E1) > KM 27 and

actual header temperature < KM 03 – 2 K

Mixer circuit pump MKP "OFF":

Actual (wood burning) boiler temperature (E1) ≤ KM 27 – KM 28

or actual header temperature > KM 03

b) Changeover between buffer and Wolf boiler by means of

a three-way diverter valve (= 3WUV):

Whether the heating or cylinder circuits are supplied by the

buffer or by the Wolf boiler depends on the position of the three-

way diverter valve. The heating and cylinder circuit demands

are exclusively issued by additional mixer modules.

Position 3WUV AB → A (= control 3WUV):

- in case of heating demand and actual header temperature >

KM 29

- in case of cylinder demand

and actual header temperature >

set header temperature

Position 3WUV AB → B:

- heating demand ends or actual header temperature ≤

KM 29 – KM 30

- cylinder demand

ends or actual header temperature ≤

set header temperature - 2 K

With outside sensor frost protection, the 3WUV always remains

in position AB → B

Also applicable to cylinder frost protection
