Central Heating Does Not Turn Off
I installed the system, and it worked normally for six months.
This week, however, my house radiator keeps heating.
I removed all cables from CH_NO, HW_NC, and HW_NO.
When I tested CH_NO, it still shows 240V even after turning off the central heating in the app or through the wireless receiver (programmer). Could the wireless receiver (programmer) be defective?

Looks like it. Might be worth hitting it. (Stuck relay).

@henryhung Hello. Reiterating @Montage that looks like a stuck relay problem. A sharp tap with the handle of a screwdriver may release the relay. If that is the problem, best to ask your supplier/Tado for a warranty replacement.
