Prove valve operation
Demand, actuator travel, valve movement and thermal response require observation under load.
System component / control valves
CONTROL AUTHORITY AT THE INTERFACE.
Valve selection, movement and differential pressure shape domestic-hot-water stability and return-temperature performance.

HIU TECH / TECHNICAL SCOPE01—03
Network performance
Passing, restricted or unstable valves can influence standing loss and primary return temperature.
Attendance required
Conclusive diagnosis requires an engineer on site to measure temperatures, pressures, flow, electrical supply and control response under operating conditions.
