Diagnose wall thermostat/controller not communicating with HIU

£50

Balham, Greater London

21st Sep 2026

I’m looking for an experienced heating/HIU engineer to diagnose an issue with the heating controls in my flat. I have an HIU (Heat Interface Unit) and a wall-mounted heating controller/thermostat. The wall controller does not appear to be communicating with the HIU correctly — changing the heating settings/turning the heating on does not seem to trigger the HIU or radiators. The HIU has previously had a faulty actuator valve head replaced. The previous engineer replaced the actuator and got the heating working, but I don't think the wall controller/controls were properly investigated. I therefore need someone who understands BOTH: HIUs / Heat Interface Units Heating thermostats, programmers and control systems The communication/connection between the wall controller, receiver/relay and HIU Electrical/wiring diagnosis where appropriate I’m looking for someone to diagnose the actual fault rather than simply replace the actuator again. Please only apply if you have experience with HIUs AND heating controls/thermostats. I can provide photos of the HIU and wall controller, as well as the previous engineer's report.
