What it is

The Ideal 174981 is a printed circuit board (PCB) supplied as a retro kit for Evo Heat appliances. It monitors and controls every process occurring throughout the system via switches, thermostats and sensors, and it enforces safety measures by shutting down boiler functions if internal readings indicate a fault, such as high pressure or low water levels. The board is used across the Ideal Evo HE and Esprit 2 ranges.

Signs this part needs replacing

  • Boiler fails to fire or repeatedly goes to lockout
  • Fault codes or error messages shown on the boiler display
  • No response to the room thermostat or programmer
  • Intermittent shutdowns or erratic burner behaviour
  • Blank or dead display panel

Before you order

  • Check the GC number on the appliance data badge against the compatibility list to confirm the board suits your model.
  • Compare the part number on the existing board; 174941 and 1780742 are listed as alternative numbers for this item.
