Page 3: Introduction
INTRODUCTION The MicroVision microprocessor-based Boiler controller has been designed to monitor and control Total Dissolved Solids (TDS) in terms of electrical conductivity measured in micro Siemens per centimeter (uS/cm). A set point of the desired conductivity is entered into the controller through the front panel. -
Page 4: 4-20Ma Output
Interlock MicroVision has a dry contact interlock option for input number 5 that will de-activate all of the control output relays upon an interlock condition indication. The interlock input requires that an auxiliary relay (not supplied) is installed across the boiler operation controls to produce a dry contact closure when the boiler is online and an open circuit when the boiler is offline. -

Page 6: Location
Location Select a mounting location convenient to grounded electrical and plumbing connections. It is recommended that you mount the controller on a wall or other vertical surface with adequate lighting at a comfortable level. A mounting-hole template is supplied with your controller. Installation should comply with all national, state, and local codes. -
Page 7: Sensor Installation
Sensor Installation The controller is supplied with a temperature compensated or non temperature conductivity sensor (probe). The probe location must be in a position where adequate flow is going around and through the probe (Fig. 4) so that the controller will be able to display a good measurement. -
