Seeing a strange issue with EBP-175 unit. This UNIT provides hot water to waterbase heating as well as domestic hot water. What's happening now is when you take a shower after some time the water turns cold and boiler doesn't seem to kick in to produce additional hot water. The workaround is to force the heat ON so it makes the boiler produce hot water since these 2 share the same water tank. It appears that something that controls domestic hot water doesn't send the signal to the boiler control board.
Any thoughts please?
