bit of ahead scratcher with a Rayburn 480K, recently installed appeared to function correctly for Ch and HW although when programmer is off the Ch still runs if the room stat calls for heat. An integral single channel programmer is fitted as well as a separate toggle switch giving the option of CH&HW or just HW. The cylinder stat is honeywell L641A room stat T6360. Could it be the programmer has been bypassed via incorrect wiring in the wiring centre or faulty programmer.
Any thoughts/ suggestion appreciated before we tackle the wiring.
