Have this manual in the palm of
your hand by FG Finder application.
1. DESCRIPTION
e
MT-516
is a temperature controller for cooling or heating applications. Equipped with a cyclic
timer output, it can also be used as alarm output, with the option of an internal audible alarm (buzzer), or
second cooling or heating stage. Another feature available is the turning off of the control functions,
e
making the MT-516
operate only as a temperature meter. Through an intelligent function
blocking system, it prevents unauthorized personnel from changing the control settings.
Product conforming to UL Inc. (United States and Canada).
2. SAFETY RECOMMENDATIONS
- Check the controller for correct assembling;
- 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 Personal Protective Equipmenet (PPE);
- For application at sites subject to water spills, such as refrigerated cabinets, 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.
3. APPLICATIONS
• Milk cooling tanks
• Refrigerated counters
• Air conditioning with automatic winter/summer system
