EXPLANATORY SKETCH
MOUNTING
TERMOMAT 12: TERMOVAR-valve (5) and two pumps (6) are mounted in the return-pipe between the boiler and
storage tank according to the explanatory sketch. At delivery the TERMOVAR-valve (5) is for right-hand
installation. For left-hand installation the inside parts of the valve must be turned 180°.
TERMOMAT 15: Pumps (6) and TERMOBAC DB40 return-flow preventer (7) are mounted in the return-pipe
between boiler and storage tank. TERMOBAC DB40 is mounted between pumps. The fat arrow must point to the
boiler.
Temperature sensor Tk (2) is to be placed inside the sensor housing (4) on the upper part of the boiler.
N.B! The sensor must not be placed on the outgoing pipe as this might disturb the function.
Temperature sensor Ta (3) is placed inside the sensor housing (4) on the upper part of the storage tank. The
sensor can also be taped on the outgoing pipe max 10 cm from the storage tank connection. Thereafter it
must be insulated.
The sensors can be lengthened up to 18 m with factory delivered wires.
FUNCTION
TERMOMAT measures the temperature difference between heating boiler and storage tank. It controls the
charging pump and the heat-collecting pump. When a pump is running a LED is on. TERMOVAR-valve ensures a
minimum return-water temperature in the boiler. The valve opens at 72°C.
TERMOVAR and TERMOBAC DB40 valves are designed to avoid self-circulation in two directions.
There are two programs for additional heat, YES and NO. When using more cost-effective additional heat, for
example pellets, YES is normally selected. For more expensive additional heat, for example an electric element,
NO is recommended. The program is selected with knob D. See page 6.
