4. TECHNICAL SPECIFICATIONS
Periodical defrost may be performed with
MT-512
e
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-512
e
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-512
e
2HP
can also be set for heating.

(United States)
- Check the controller for correct fastening;
- Make sure that the power supply is off and that it is not turned on during the controller installation;
- Read the present manual before installing and using the controller;
- Use adequate
(PPE);
- For application at sites subject to water spills, such as refrigerated counters, install the protecting vinyl
supplied with the controller;
- For protection under more critical conditions, we recommend the Ecase cover, which we make
available as an optional item (sold separately);
- The installation procedures should be performed by a qualified technician.

6.2. Temperature sensor connection
- Connect the sensor wires to terminals ‘1 and 2’: the polarity is not relevant.
- Length of the sensor cables can be increased by user himself to up to 200 meters, using a PP 2x24
AWG cable.
- For immersion in water, use a thermowell (Image VI - item 12), available in the Full Gauge Controls
product line (sold separately).
