3.28 E8 Controller and BCM Terminal Assignments

On the rear panel of the E8 controller, there are two terminal blocks, one of which is for the

mains (120 V) connections, and the other for the low voltage connections.
The main controls, necessary for the C/H system management and for the boiler control, as well

some components which are part of the boiler housing, must be connected to the terminal

blocks. See Figure 3-23 for a wiring diagram showing the E8 controller terminal wiring, and see

Figure 3-24 for a wiring diagram of sensor and BCM terminal wiring.
