Operating and Maintenance Instructions

Introduction

Commercial Dual Fan Controller, mains powered with enclosure, controls two fans Stop/Run and Low/High
speed. Speeds preset by on-board trimmers, selected by 230VAC and volt-free inputs. Optional alternate fan run
with selectable duty (changeover) period, or simultaneous (Load Share) and Single Fan operation.
With LED indicators and alarm output. Configurable options set by on-board DIP switches.
