What do the symbols mean on a thermostatic radiator valve?
Radiator valves will have numbers or symbols representing how much heat the radiator is currently giving out represented by a level between 1 – 6.

Should a TRV be on the flow or return?
Most modern thermostatic radiator valves are bi-directional – so can be fitted on either the flow or return pipe of your radiator. However, it’s always best practice to fit the TRV on the flow pipe that enters your radiator.
