2 zone hot water tank control senario

I have a downstairs and an upstairs thermostat. The downstairs thermostat controls the hot water and central heating. The upstairs thermostat controls the upstairs central heating. When the thermostats demand heat the solenoid valve on the hot water tank opens to allow flow. When there is no demand for heating the solenoid valve closes. All of the radiators have smart thermostats both downstairs and upstairs. My question is should I put the solenoid valves in manual and allow the radiators to control the temperature? I have noticed that when the thermostat on the wall calls for heating and all the radiators are satisfied with temperature the boiler comes on unnecessarily. Anyone else have the same setup and issues?

    Can anyone help with my scenario? Any help would be appreciated. I only one controller so both wall thermostats are connected to it.

    @Miller Hello. It’s hard to give any answers from your description. Do you mean that you have Tado installed? Or asking for how to pick from the menu of products? . Can you provide more detail of what you have installed. The detail will help users to help you.
    EDIT: typo.

    Hi wateroakley, thank you for your reply. Downstairs - I have a wired smart thermostat with central heating control, hot water control and 3 smart radiator thermostats. Upstairs - I have a wired smart thermostat that controls central heating upstairs and 5 smart radiator thermostats. All are Tado. All are connected to one wireless receiver downstairs. The hot water has been turned to always on and the boiler turns on when someone has a shower or hot water is used. The hot water tank is upstairs and has two solenoid valves, one for the downstairs central heating and one for the upstairs central heating. Each one are controlled by the wired smart thermostats (one upstairs and one downstairs) that open when heat is demanded. I sometimes find that if all the rooms are satisfied with the desired temperature and wired thermostat is demanding heat the boiler turns on but has nowhere to flow as all the radiators valves are shut as the temperature is satisfied. I have monitor this constantly as I don’t want to damage the boiler. It also happens vice versa where the rooms are cooler than the set temperature but receive no flow as the wired thermostat isn’t calling for heat so the solenoid valve stays closed on the hot water tank. To try to help, I have offset the temperature for the wired thermostats to -1 degree but this away requires constant monitoring. Hope this helps and thanks again for responding.
