SUPPLY TEMPERATURE SENSOR AND ADAPTER
Supply temperature sensor T1 is fastened on a non-
insulated part of the supply pipe 1 meter after the
mixing valve. For optimum temperature measuring
the pipe has to be insulated afterwards. Adapter in
connected to A, supply sensor T1 to B.

sensor T1
Desired temperature is set with knob D and E. When
knob D is set over 40ºC the temperature scale is on
knob E. In Picture 3 the temperature is set on 55°C.
When motor opens the valve the red LED A is bright
and when motor closes the valve. The green LED B is
bright. When motor doesn't move no LED is bright.
TURNING DIRECTION OF VALVE MOTOR
Right or left turning direction of motor is set with
knob G. At delivery the knob G is set for right open-
ing direction R, which means the motor opens the
valve clockwise. For left opening direction the knob
G is set on L, which means the valve will open anti-
clockwise.
MOTOR PULSE
Normal motor pulse is 1 sec. If the supply tempera-
ture is not stable owing to the flow speed, the mo-
tor pulse can be chosen between 2 sec and 0,3 sec
with knob G. For example if the difference between
supply and return temperature is over 10°C and the
temperature in swinging the knob G is turned to-
wards 0,3 sec.
TROUBLE SHOOTING
If the system should not work satisfactorily –
check that:
1. the boiler or storage tank temperature is correct
2. the power supply and condition of fuses
3. the circulating pump is working
4. the gate valves are open
5. the mixing valve turns easily
6. there is no air in the system
7. the disengaging button H is in "A"
AUTOMATIC-position
8. the system installation is correct and it
works with manual operation
9. the resistance value of the supply sensor T1 is
correct. See picture 4.
SENSOR RESISTANCE
The resistance is measured at the two wires in the
middle of the 4-wire cable contact.
