DIGITAL CONTROLLER AND INDICATOR FOR HEATING OR COOLING WITH NATURAL DEFROST THROUGH COMPRESSOR SHUTDOWN

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 16Arelay 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-512e2HPcan also be set for heating.

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.

Evolution line products has a frontal IP-65 protection, Flatec key for easy access, four digits display and exclusive accessories* as the key programmer EasyProg and the protective case Ecase.
