Boiler type Vmax plus (VM110P)

Error code Err 66

Cause:

Incorrect Frequency

Solution:

The controller accepts a line voltage frequency of 60Hz ± 2%; if outside this range the controller may be damaged or function incorrectly. If using a generator as a power source, install a UPS (uninterruptible power supply) between the generator and boiler.
