Control mode Explanation
Automatic
H23 controls the supply water temperature automatically according to the
need for heating and possible time programs (weekly schedule and holiday
calendar) or according to the home/away control.
Manual The actuator remains in the position defined in manual mode until the control
mode changed to automatic.
The actuators position in manual mode is changed with ”Actuator manual con-
trol” –setting. If 3-state actuator is in use, the direction of the control of the
valve is shown (open/close).If voltage controlled actuator is in use, the position
of the valve is shown as percent value.
Manual mech. (voltage controlled actuator) When the control mode is manual mechanic, the supply voltage from H23 to
actuator is cut and the position of the valve can be changed straight from the
actuator.
