Control System Installation and User’s Guide
Commercial Application using ESO3 and SunTouch
®
Control System
(Single Body System)
Using a Emergency Shut-Off Switch (ESO3), circuit board, and a spring wound timer switch
(Intermatic
®
Transformer equivalent), a SunTouch
®
Control System single body system (P/N 520859)
can be configured for a commercial application. A typical configuration, using a single speed pump is
shown in the “Commercial Application Connection Diagram” below. As shown, the commercial spa
jet pump is controlled by the spring wound timer switch and AUX 1 (Jet pump) is programmed by
SunTouch to operate from 5:00 AM to 12:00 AM. When the Emergency Shut-Off Switch is pressed, both
relays will disengage. If the pool or spa light is controlled by AUX 2, the light will remain operational.
