1. DESCRIPTION
The TC940Ri plus is a temperature controller for frozen products that manages the defrost
start and end cycles only when necessary, based on the temperature of the evaporator. It has a
timing function for collection of the residual refrigerant gas before defrost starts, improving
performance of the refrigeration cycle and reducing power consumption. Its fourth output is used
to trigger an alarm or turn off lamps.
It also features a configurable digital filter, which increases the response time of the S1 sensor to
avoid activating the compressor by quick temperature changes, and a serial output for
communication with the Sitrad - management software via internet.
The TC940Ri plus also has a configurable digital input used for performing one of the
following functions:
-Perform external defrost synchronism;
-Change the setpoint for night mode;
-Generate a visual and audible alarm to indicate the opening of the freezer door, for example;
-Inhibit control functions (standby mode).
*In the F43 description in this manual, each of the above functions is defined in detail.
Product complies with UL Inc. (USA and Canada) and .

4. CONFIGURATIONS
4.1 - Setting the control temperature (SETPOINT)
Operating temperature: 0ºC to 50 ºC / 32°F to 122°F
Dimensions: 71 x 28 x 71 mm
Press the key for 2 seconds until the message appears on the display, then release
it. The working temperature for daytime mode will appear (setpoint 1). Use the keys to
change the value and, when ready, press the key to save.
After setpoint 1 temperature has been set, the message[SP2]is displayed, and then the working
temperature for nighttime mode (setpoint 2) will be shown. Use the same procedure to change the value
and, when ready, press the key to save.
