control systems available today. This powerful, user-friendly control system provides the flexibility
and performance needed for a stand-alone unit as well as multiple units tied into a network system.
MicroTech’s state-of-the-art design will not only permit your chiller to run more efficiently, but will
also simplify troubleshooting if a system failure occurs. Every MicroTech controller is programmed
and tested prior to shipment to ensure a trouble-free start-up.
