Good morning,

We have a few HPW units installed on a few sites. Recently we have problems with the PCB being faulty. After providing the model and serial number and receiving the new PCB with new EPRONS we find that the units do not communicate with the Hiromatic controllers, however the switch on and rotate as set up. The last replacememt the unit won't come on or display and values to the Hiromoatic.

We have double and triple checked the jumpers and on the new PCB while setting up. Has anyone had a similar problem?

TIA
Mario
