MT-512E 2HP Digital Temperature Controller | Cooling & Heating w/ Off-Cycle Defrost (115/230V)

The MT-512E 2HP is a digital temperature controller designed for precise cooling or heating control in commercial refrigeration and HVAC applications. Featuring a single relay output rated for up to 2HP, it supports both cooling and heating modes, making it ideal for medium-temperature environments.

The controller includes a built-in cyclical timer for natural (off-cycle) defrost, which can be performed automatically or manually. A configurable digital filter allows for adjustment of sensor response time, improving temperature stability in sensitive environments.

Additional features include a tamper-proof function to prevent unauthorized changes and a control shutdown mode that disables outputs while maintaining temperature display functionality.

With dual voltage compatibility (115/230V), the MT-512E 2HP is well-suited for refrigerated cabinets, display cases, greenhouses, and heated food service applications.
