2. Hang Farm Hand Heat Zone Controller with four screws and the plastic mounting
brackets included.
3. Make sure all power supplies are disconnected before breaking any wires, or
reaching into the enclosure.
4. Open the Heat Zone Controller and find all connections. Refer to wiring diagrams in
back of this manual.
5. Run sensors out to locations inside the house. Be sure that the sensors are in a safe

wiring diagram in Section 9.7.
