Wiring the Heat Exchangers:
1. Run two 18-gauge wires, red for (+) and black for (-),
from each particular heating zone’s heat exchanger to
the electronic controller. Reference Figure 22.
2. Label the wires indicating the heating zone they pertain
to (e.g., Living Room, Bathroom, Bedroom, etc.).
3. Insert all heat exchanger wires into the appropriate ter-
minal/heating zone location on the electronic control-
ler. Reference Figure 21 and Appendix A.
4. Wire all heat exchangers in a zone in-series. Reference
