Robertshaw - MT-512E-2HP Temperature Control

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.
