10. Maintenance
Check the calibration of your sensors at least once per quarter. To do this, you will need to have two
persons. One at the sensor with a trusted thermometer, and one at the controller to set the sensor to
the proper setting.
11. Wiring Diagrams
All wiring connections for stages, curtain machines, variable speed fans, and curtain sensors inside
the controller are made without terminals on the end of the wire. To make the connection, strip about
¼” of the insulation off the wire, and follow the diagram below.
1. Insert a small screwdriver into either the hole shown in the diagram.
2. Insert the stripped end of the wire into the hole shown in the diagram.
3. Remove the screwdriver, and tug slightly on the wire to check that it is snug.
Warning!
Do not connect more than twelve (12) amps of load to any one stage.
