Hallo!I have an elderly, remote potterton Tankstat

Customer Question

I have an elderly, remote potterton Tankstat with a temperature setting control on it. This had been tending to 'chatter' for some time and now fails to control the temperature at all. The unit is easily 'unplugged' from its base showing 4 terminals - TP3 TP4 TP1 TP2, in that order. There is also a 'J1' 2-pin Terminal fixed plug to conect to a 2 wire tank unit. Is it the wall or tank unit likely to need replacement?
