What it is
The Ideal 178159 is a CUI wiring harness manufactured by Ideal for its Commercial range. It forms the electrical link between the control unit interface and the rest of the appliance wiring on iMAX XEL boilers. The harness carries the low-voltage signals and supplies that the control unit needs to run the burner sequence and report status.
