Information on replacing the HBMU heat management unit

If replacing the HBMU heat management unit, the
"Service Assistant" must be used.

See spare part installation instructions and inter-
net address:

Replacing the power cable

When replacing the power cable, only use the power
cable available as a spare part from Viessmann.

Replacing the HMI connecting cable

Please note

Incorrect routing of the cable can lead to heat
damage and impairment of the EMC properties.
For positioning and securing of the cable (fixing
point of the cable tie) see connecting cable
installation instructions.
