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.
198 Daylight saving time changeover
Circuit Setting range Factory setting
I ON / OFF ON
Choose whether you want the change to summer / winter time to 
be automatic or manual.
ON:   The controller’s built-in clock automatically 
changes + / - one hour on the standardized 
days for daylight saving time changeover 
for Central Europe.
OFF:   You change manually between summer and 
winter time by setting the clock backward 
or forward.
