Periodical defrost may be performed with MT-512E 2HP by stopping the compressor (natural defrost) and forcing defrost manually. It is provided with a powerful 16A relay for actuating loads of up to 2HP, in addition to a command output combined with a timer for programming refrigeration and defrosting times. Another feature available is the turning off of the control functions, making the MT-512E 2HP operate only as a temperature indicator. It is also provided with a configurable digital filter, which has the purpose of simulating mass increase in the environment sensor, thus increasing its response time, i.e., it renders the sensor response slower (delay). Through an intelligent function blocking system, it prevents unauthorized personnel from changing the control parameters. MT-512E 2HP can also be set for heating.

It features a single relay output, for cooling or heating purposes, combined to a cyclical timer for natural defrost. The natural defrost can be forced or performed through an off refrigeration cycle. It also features a configurable digital filter, which has the aim of simulating an increase of mass in the environment sensor, thus increasing its response time, that is, the sensor response becomes slower. In addition to those features, the MT-512E 2HP has tamper-proof function that blocks the keypad preventing unauthorized users changing its settings, and a control function shutdown that deactivates the controlling outputs turning the instrument into a digital temperature indicator.

This product is CE, UL and NSF certified. According to UL laboratory tests, this product is also suitable for installations with R290 and R600a gases.
