7 Maintenance
7.1 General information
Important information
To ensure the correct and safe operation of the system, this
information must be read and followed.
Following these instructions will help avoid hazards and downtime
and increase the reliability and life of the system.
Function and energy savings
The heat interface unit is a compact station that can operate in a
system with several units or as a supplement to an existing heating
system. It is assigned to a residential unit and is used to measure
and control central heating and heating of the water.
The heat interface unit combines:
• water heating in the flow system via a plate heat exchanger
(water heating is controlled without auxiliary energy)
• the metering of the energy consumption for central heating and
hot water and, as an option, the amount of cold water
• heating control in the apartment with hydraulic balancing and
energy saving by ECO-mode.
Hot water is only prepared when needed. Service water is not stored.
This is one of the most convenient ways to heat fresh water. This
enables dispensing of large amounts of hot water. Restrictions are
only imposed by the central heating.
Water heating
Caution!
All water pipes are filled and pressurised.
The cold water supply for the apartment is provided via the central
house connection and distribution line.
The heat interface unit is equipped with a central shut-off ball valve
for cold water (F). As an option there is a shut-off ball valve for
installation purposes.
All ball valves should be exercised (open-close) at regular intervals
(about once per month).
The ball valves (E) and (F) should only be closed for assembly/
disassembly reasons.
Water hygiene
Although the water system follows the flow principle, which is the
most hygienic method of water heating, the water pipes should
always be flushed if not used for a longer period.
The tapping duration should then be around 1-2 minutes. The water
must be allowed to run at least every 7 days for about 1-2 minutes.
7.2 Turning off heat interface unit
Note
If droplets of water are detected, call a qualified service
personnel.
Ball valves must be closed in the event of malfunctions. A visual
inspection is required every 3 to 6 months.

If the system is to be shut down for a longer period:
• Close ball valves A, B and F. Close the cold water tap.
• Protect the heating unit against frost.
• Let the hot water run for about 5 minutes at restart.
• Switch off the controller (pull out the plug, settings remain
saved).
