Viessmann VIESMANN VITOLIGNO 300-H Technical Manual page 27

Ecotronic control unit for Vitoligno 300-H
Differences between the extension kits listed below
■ Part no. ZK01 270
– For direct connection to the Ecotronic
– For systems without solar thermal installation:
For heating circuit 1 with mixer and heating circuit 2 with mixer,
direct control by the Ecotronic
– For systems with solar thermal installation:
For heating circuit 1 with mixer, direct control by the Ecotronic
■ Part no. 7301 062, Part no. 7301 063
Extension kits with mixer PCB
– For connection via KM BUS
Information on extension kit, part no. ZK01 270
For DHW heating, the following must be ordered separately: The
"temperature sensor set for the solar circuit", part no.: ZK01 271 is
used as a cylinder temperature sensor for DHW heating (only one
sensor is required). The contact temperature sensor included in the
extension kit delivery is not required.
Mixer extension kit with integral mixer motor
Part no. ZK01 270
For wiring on site.
Components:
■ Mixer motor
■ Flow temperature sensor as contact temperature sensor (Pt1000)
■ For Viessmann heating mixers DN 20 to 50 (welding fitting) and R
½ to 1¼ (not for flanged mixers).
■ For systems without solar thermal system: For heating circuits 1 and
2 with mixer, directly controlled by the Ecotronic.
■ For systems with solar thermal system: For heating circuit 1 with
mixer, directly controlled by the Ecotronic.
The mixer motor is mounted directly onto the Viessmann mixer DN 20
to 50 and R ½ to 1¼.

For DHW heating, the following must be ordered separately:
For DHW heating, the temperature sensor with part no. 7438 702 is
used as a cylinder temperature sensor (sensor well to be ordered sep-
arately if required).
The contact temperature sensor, which is part of the extension kit
delivery, is used as a return temperature sensor.
