What it is
The Ideal 179079 is a wiring harness for external controls, used to connect heating controls such as room thermostats and programmers to the boiler's control circuitry. It is manufactured by Ideal for the Logic+ Combi and Logic Max Combi ranges, along with Ideal commercial appliance parts. The harness carries the low-voltage switching and demand signals between the external control and the boiler PCB, so a sound connection is essential for correct heating and hot water operation.
Signs this part needs replacing
- External controls fail to bring the boiler on, or the boiler ignores a call for heat
- Intermittent operation of the thermostat or programmer with no obvious fault at the control itself
- Visible damage to the harness: chafed, scorched, brittle or broken conductors
- Loose or corroded plug connections at the boiler end of the harness
- Fault codes or lockouts linked to control circuit communication
Before you order
- Check the appliance GC number and model against the compatibility list to confirm the harness suits your boiler
- Note the alternative part number 1777741 when cross-referencing older documentation or stock records
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
