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.
