I have a problem with my central heating control box. The box is located next to the hot water tank on the floor.Inside is a circuit board with a relay fixed to it which is oscillating when the water heats up.The wires also goto to the valve and pump.The control comes from a Danfoss TP5 unit which is located down stairs.The only identification is a circuit board number PMT-DP.I cannot identify it to get a replacement board.Anybody with any ideas where I might locate it or how I could replace it with an alternative.(I am told this is an unusual configration)
