    We have a potterton ep2001 programmer and if you switch both CH and HW to off on panel it goes off like it should, then all of a sudden the LED's on CH and HW come on and boiler fires up, how can this be? Also when the controller should go off when set time both LED's stay on and boiler still works. Basically its on all the time
