How To Use The Data Brochure
This brochure is organized into four main sections. They are: 1) Sequence of Operation, 2) Installation, 3) Control Settings, and
4) Testing and Troubleshooting. The Sequence of Operation section has six sub-sections. We recommend reading Section A: General
of the Sequence of Operation, as this contains important information on the overall operation of the control. Then read the sub
sections that apply to your installation.
The Control Settings section (starting at DIP Switch Settings) of this brochure describes the various items that are adjusted and
displayed by the control. The control functions of each adjustable item are described in the Sequence of Operation.
