I have a GHL Profilux Plus II, 4 unit dosing pump and a 6 socket powerbar. I have been using them for a few years without any problems but*today*the green power and yellow communication lights on the powerbar were flashing and none of the sockets were activated when they were programed to be on. I was using the powerbar to control two heaters controlled by the GHL temperature probe and only realised that there was a problem when the temperature of the tank water had dropped.

I have tried to reassign the sockets on the powerbar but it is still not responding although the doser appears to be working as it should.*

Have you any advice as to how I might rectify the problem?

Thanking you in advance for your assistance in this matter.

Kind regards,

Diane
