1. DESCRIPTION
2.
3. TECHNICAL SPECIFICATIONS
The
MT-512
e
2HP
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-512
e
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.

FOR INSTALLATIONS WHERE A SEALING IS REQUIRED TO AVOID LIQUID CONTACT,
THE CUT FOR THE CONTROLLER MUST BE OF 70,5X29mm MAXIMUM. THE SIDE
LOCKS MUST BE FIXED SO IT PRESSES THE RUBBER SEALING AVOIDING
INFILTRATION BETWEEN THE CUT AND THE CONTROLLER.
