174 Motor protection
Circuit Setting range Factory setting
(I) / (II) OFF / 10 ... 59 min. (OFF) / (OFF)
Prevents the controller from unstable temperature control (and
resulting actuator oscillations). This can occur when there is
no DHW tapping, i.e. when the load is only due to the DHW
circulation, or when the heating demand in the heating circuit
is very low. The motor protection increases the lifetime of all
involved components.
OFF: Motor protection is not activated.
10 ... 59:
Motor protection is activated after the set
activation delay.
A high value should be used for DHW
installations with many consumers.
