Wiring

How to Wire the Series 733/734

The Series 733/734 wiring is illustrated by model number option. Check the terminal designation sticker on the control and compare your model number to those shown here and also the model number breakdown on the inside back cover of this manual.

When you apply power without sensor inputs on the terminal strip, the Series 733/734 display alternates parameter data and Er07 at a 3 second rate.

This error indicates an open sensor or A/D error. Remove power to the control and connect the sensor properly. All wiring and fusing must conform to the National Electric Code and to any locally applicable codes as well.

Use Figure 6 as a location reference when wiring your unit.
