I. Introduction

MicroTron controllers are microprocessor based menu driven units for control of recirculating and other

water applications. All settings are entered into the controller through a simple front panel keypad which

includes relay test keys.

Model Numbering

MicroTron controllers have several base functions and optional features available. Your unit may be supplied 

with one or more of the options that are described in this manual. To determine what features apply to your 

unit, check the model number label located on the controller enclosure.
