￿.￿ Commissioning of the heating system
Before starting the circulating pump, the circuit must be ￿lled with water. Water should be ￿lled to a basic pressure of
￿–￿.￿ bar. From a water column height of ￿￿ m, the basic pressure increases by ￿.￿ bar per metre of height. The maximum
water column height is ￿8 m. The maximum operating pressure is ￿.￿ bar. After increasing the pressure, the circuit must
be completely vented. Venting of the indoor unit can be performed on the upper right side of the plate exchanger. After
starting the circulating pump, the plate exchanger must be completely vented, which is indicated by smooth running of the
circulating pump. Before starting the compressor, it is recommended to let the circulating pump run for at least ￿￿ min.
For more information, see the Installation Manual, Chapter Connection of the heat pump to the heating system.
￿.￿ Activation
After ￿lling and venting, you can test the electrical equipment of the heat pump.
Switch on the TECHNOLOGY circuit breaker and, after the controller system initializes, press the H/C button in the
Overview section. This activates the circulating pump. Check the state of the hydraulic system. If the ￿ow and pres-
sure are OK, you can switch on the remaining circuit breakers. Check the settings and check the operation of all heat pump
devices, especially the outdoor unit (for DHW heating settings, see the DHW chapter in the User Manual).
