What it is

The Ideal 174670 is a slave control module for Ideal Commercial boilers, supplied as a printed circuit board assembly. It forms part of the control arrangement on the Imax Xtra range, where the slave board works alongside the main control to manage the appliance's operating sequence. It is a direct replacement item for the original board fitted to these commercial units.

Signs this part needs replacing

  • The boiler fails to run through its ignition or operating sequence
  • Fault codes appear on the appliance display that point to the control board
  • The appliance locks out repeatedly or runs intermittently
  • Controls or connected components do not respond as expected
  • Visible damage, discolouration or burning on the board itself

Before you order

  • Confirm the appliance model and serial number against the compatibility list, as the slave module is specific to certain Imax Xtra units
  • Check whether the fault lies with the slave board or the main control board before ordering
  • Isolate the electrical supply to the appliance before removing or fitting any board
  • Note the existing wiring connections and board orientation before disconnecting
