Can anyone help please? This programmer has been working fine till I changed the settings to increase the hours for CH and water. since then central heating is not coming on but water gets heated up. I have reset the programmer and still no CH but water is fine.
Any suggestions.
I thought the programmer has become faulty and bought another one but dont know how to change it.
thanks
