Full Gauge Controls MT-516RVTi plus Manual

1. DESCRIPTION
MT-516RVTi plus
The integrates a heating or cooling thermostat with a cyclical timer and a
TrueRMS voltage monitor. Through the F13 and F14 functions is possible to determine the voltage limits
that the thermostat output can be active, this way protecting the compressor. Using True RMS*
technology the controller is capable of measuring the voltages in a variety of different situations in the
electrical grid, thus providing greater precision in the protection of the components of the application.
Product complies with UL Inc. (United States and Canada).
*True RMS: Is the real and effective voltage value which also includes the voltage generated by high frequency
noise in the distributing network (harmonic distortion). This is the actual voltage applied to the connected load
(example: electric motor, compressor). This method allows the precise voltage measurement for any type of
wave form. Other measurement methods give correct value of applied voltage only for perfect sine wave forms.
2. APPLICATION
• Milk cooling tanks
• Chambers and counters
• Heat pumps

(1) F02 - Temperature indication offset
The F02 functions allows for the correction of any changes in the reading, resulting from a change in the sensor or
alteration of the length of the cable.
(2) F12 - Cyclical timer always on when the compressor is on:
This function works for some applications, as for example, on cooling tanks for milk, where the timer commands the
agitator that must remain on while cooling is taking place.
(3) F13/F14/F16 - Operation of the voltage monitor
If the value of the voltage exceeds the limits set in F13 and F14 the compressor will be automatically turned off after the
time set in function F16 has lapsed.
The led "VOLTS" will slowly blink along with the Indication of the grid voltage on the display.
In the event that the voltage returns to the limits established, the compressor will only be turned on again after the time
scheduled in the F16 function has ended.
To deactivate the voltage monitoring, all you have to do is adjust functions F13 and F14 to the same value.
(4) F17 - Display indication mode
Function F17 allows you to choose the measurement that will be displayed during normal operation:
