5.5.2 AM MINI, EM Single-circuit Heating System
Typical usage is for floor heating, except for “dry system of floor heating”. This connection is not
suitable for radiators. In this method of direct connection of the heat pump to the heating
system, maximally 30% of the heating system can be equipped by local regulation. The DHW
heating is provided by a 3-way switching valve. Regarding the type of DHW tank follow
instructions in the chapter “Preparation of Domestic Hot Water”.
Warning: for good operation 10-15% propylene glycol is required, due to the 20°C
antifreeze protection of the heat pump inlet when pure water is used.
