Operation
Turning direction of valve motor
Right or left turning direction of motor is set with knob C that is located under the cover. At
delivery the knob C is set for right opening direction R, which means the motor opens the valve
clockwise. For left opening direction the knob is set on L, which means the valve will open anti-
clockwise.
Motor pulse
Normal motor pulse is 1 sec. If the supply temperature is not stable owing to the flow
speed, the motor pulse can be chosen between 2 sec and 0,3 sec with knob C. For example
if the difference between supply and return temperature is over 10°C and the temperature
in swinging the knob C is turned towards 0,3 sec.
Longer pulse = faster movement.
Shorter pulse = slower movement.
