In order to get the ultimate benefit from your hot water module VM 240 you should read through this Installation and Maintenance Instruction. VVM 240 supplies the house with hot water and heating as well as controls FIGHTER 2010 to give optimum performance.
System description Principle of operation VVM 240 is an electric boiler intended for houses with obtained for the heating system. This temperature is water based heating. It consists of a double-jacketed determined by the outdoor temperature and the selected pressure vessel, two immersion heaters and an default settings.

It is usually easier to start the circulation pump with VVM 240 running, switch (8) set to “1”. If helping the circulation pump to start is performed with VVM 240 running, be prepared for the screwdriver to jerk when the pump starts.
Electric boiler mode The VVM 240 must be transported and stored upright VVM 240 can be set in electric boiler mode from here. This mode means the heat pump is blocked, but all and dry. The VVM 240 may however be carefully laid other components function as normal.
The total volume is 240 litres, with 170 litres in the water heater and 70 litres in the double-jacket space. The pressure vessel in the VVM 240 is approved for max 9.0 bar (0.9 MPa) in the water heater and 2.5 bar (0.25 MPa) in the double jacket space.
