Control Panels

A control panel combines many of the heating and cooling controls into a single, unified preassembled package. As a result, field wiring and control troubleshooting are greatly simplified.

A complete line of standard control panels is available for a variety of different functions. Depending on the requirements of the installation, it is possible to obtain a variety of different combinations of the following control components in a panel:

1. Transformer.

2. Line voltage and low-voltage wiring terminals.

3. High- or low-pressure cutout.

4. Two-stage cooling time-delay circuit.

5. Compressor contactor or motor starter.

6. Auxiliary relays.
