You may want to put a lockable manual TRV into a public area where you want the radiator to come on whenever the boiler or that heating zone of the property heats up.

These are popular with landlords that want to put them into hallways and ensuites etc. The landlord may choose to not put a Genius Wireless Radiator Valve in this room because they do not want to use the occupancy detection or a managed schedule for this area of the property, they are happy for it to just come on to a low heat whenever the boiler is running.

You can purchase these from plumbing merchants.
