An easy decision: The modern Pilot ONE, and the simple MPC offer a range of functionality to suit all temperature control requirements. Depending on budget and application, a controller can be selected that meets the applications requirements. If only a basic functionality is required, an inexpensive model with an MPC could be chosen. If the application requires more extensive features, a unit that has the powerful Pilot ONE controller could be the best choice. Pilot ONE models offer the added advantage of functionality upgrades with “E-grades” where the software can be updated by entering a unit specific upgrade code.
