Where is the heating flow controlled by the property?

Property management companies can control the flow of heating, because property management companies can control all pipes and valves from the joint of heating pipes to the front of residents' valves.

But the heating agreement was signed by the household and the heating company. If the property company controls the heating flow of residents without authorization, which will affect the heating quality, then the heating company and residents will claim compensation from the property company. Therefore, the property company will not control the heating flow of residents.
