on Hot water Heating Turns on

[rikleo2001]

Hi All

New to this forumn.

I recently move to aprtment, here is the current config.
1. bolier in Store room outside of kitchen
2. Danfoss 102 programmer to control the Water and heating
3. Tank inside the apartment in store.

When I select on the programmer to Water Only, my heating turns ons as well, I don't want heating during summer days.

Can somebody tell me what would be the problem?

Many thanks

motorised valve is passing or if the system is realy dated you may have a gate valve to control the heating

Thank you so much for your reply.
Now I couldn't find motorised volve. only those wheels around the pipe all 6 of them around the tank pipes.

Also I noticed then there are TRV on every single raditors. so my understanding is If I turn them off then it means raditors will be off? am I correct?

So I did it for all my house, all turned off except 2, in the living room and in the Kitchen, I moved them to x location, but still raidtors are heating up in living and kitchen, rest of the rooms and bath raditors are off. is there fault in TRV in living and kitchen?

Thanks again.
