What it is
The Ideal 177649 is an electronic controller built for Ideal heat interface unit (HIU) applications, listed against the SATKF0202 reference. It manages the electronic control side of the unit, handling the signals that govern how the HIU responds to demand. It is supplied as a serviceable spare so an existing controller can be swapped out without replacing the wider assembly.
Signs this part needs replacing
- The HIU fails to respond to heating or hot water demand
- The controller shows no display or no indicator activity when power is applied
- Fault codes or error indications appear on the unit
- Operation becomes intermittent, with the unit cutting in and out without a clear pattern
- The controller is visibly damaged, heat-affected or corroded
Before you order
- Confirm the appliance model and serial number against the compatibility list below
- Check that the existing controller carries the number 177649 or the alternative 1782980
- Inspect any seals, gaskets or wiring connectors disturbed during removal and replace them if they are perished or damaged
- Isolate the electrical supply to the HIU before starting any work
