Controller Installation & Wiring
Controller Mounting
It is important to mount the controller in a location that is free from
extreme high or low temperatures, moisture, dust and dirt. Be careful
not to damage the electronic components when mounting the control-
ler. The HB Mini Controller mounts in the HB unit control panel using
the 4 plastic standoffs located on the HB control enclosure mounting
base.
Important Wiring Considerations
Please carefully read and apply the following information when wiring
the HB Mini Controller.
1.
All 24 VAC wiring must be connected so that all ground
wires remain common. Failure to follow this procedure
can result in damage to the controller and connected
devices.
2.
All wiring is to be in accordance with local and national
electrical codes and specifications.
3.
Minimum wire size for 24 VAC thermostat wiring should
be 22 gauge.
4.
Minimum wire size for all sensors should be 24 gauge.
5.
Be sure that all wiring connections are properly inserted
and tightened into the terminal blocks. Do not allow wire
strands to stick out and touch adjoining terminals which
could potentially cause a short circuit.
6.
Be sure all modular wiring harness connectors are seated
firmly in their respective modular connectors on the HB
Mini circuit board.
