Overheating
- For HY-
MAG
DN100 only -
Temperature safety control was released, i.e. the solenoid coil in the water
part is overheated. Check whether or not exterior influences or stagnation of
water may be the reason.
If there is no exterior influence visible, control operation and check whether
cooling takes place. The operation mode starts automatically again once the
coil temperature is cooling down and the contact switching accordingly.
Inform Hydrotec accordingly should that not be the case.
