CONTROLLER FOR REFRIGERATION
AND DEFROSTING
Ver.01
TC-960Ri LOG
1. DESCRIPTION
TC-960Ri
LOG
is a temperature controller for frozen goods that automates the defrosting
processes in accordance with the needs of the facility, thus providing large power savings.
It has two sensors: one for ambient temperature and the other fixed to the evaporator that controls the
defrosting ending and the fan restarting. It is also fitted with an alarm output and buzzer that can be
activated by different events. It is fitted with two digital inputs, being able to read the supply voltage
(protecting the loads from under- and over-voltage), and an hour-meter function that indicates when the
time for compressor maintenance has come. Beyond these resources the instrument has an internal
data-logger with 70 hours of autonomy, or almost 3 days ( in a 30 seconds sample time). It also has a
digital filter for the temperature reading that decrement the response time of the ambient sensor to
prevent the compressor action by fast changes of this measurement.
2. APPLICATION
• Refrigerated Trucks
• Refrigeration chambers
• Counters

4 - CONFIGURATIONS
4.1 - Control temperature adjust (SETPOINT):
- Press for 2 seconds until appears, and release it after that. The adjusted temperature will
appear. Use and to change the value and then press to record it. The display will show
meaning that the setpoint value of the economy setpoint must be adjusted. Use the same
procedure to adjust the economy setpoint value and when ready, press to save and return to the
preferred view.
The economy setpoint will be activated in accordance with the hourly setup adjusted through functions
F57 to F62.
