Its main feature is to have a powerful relay to drive compressors up to 2HP and the defrost output has a current capacity of 10 Amp.
This product is CE, UL and NSF certified.
Evolution line products has a frontal IP-65 protection, Flatec key for easy access, four digits display and exclusive accessories* as the key programmer EasyProg and the protective case Ecase.
* sold separately
Dimensions: 71 x 28 x 71 m
Application example: walk-ins and frozen good displays.


Digital Thermostat with Defrost and Internal Data Logger


TC-900E Log Model: TC-900E Log

For frozen goods, it automates the defrosting process according to the needs of the facility (intelligent defrosting), providing energy savings. It operates with two sensors, one for room temperature and the other, fastened to the evaporator, that controls defrosting completion and fan restarting. The room temperature control has a normal setpoint and an economy setpoint, in addition to the fast freezing functionality and alarm functions indicating that the door is open. It features up to two digital inputs. One of these inputs may be configured as sensor 3* to monitor the condenser temperature and disconnect the control outputs in case of an alarm. It also features a digital filter, which is intended to simulate an increase of the mass of the room temperature sensor (S1), thus increasing its response time (thermal inertia), and avoiding unnecessary compressor activations. Its 16-Amp relay output can control compressors of up to 1 hp and the defrost output has a current capacity of 10 Amp.
TC-900E Log contain an hourmeter to count the operating hours of the compressor, and an internal real time clock that enables the creation of a defrost schedule for each day of the week. Besides, with the help of an internal auxiliary power supply, the clock keeps working even in case of a power fault for at least 72 hours.
It also has an internal memory for storing data (datalogger) and a sensor to activate the economy setpoint according to the intensity of light.
This product is CE, UL and NSF certified.
It has a serial communication for connection to Sitrad.
Evolution line products has a frontal IP-65 protection, Flatec key for easy access, four digits display and exclusive accessories* as the key programmer EasyProg and the protective case Ecase.
* sold separately
Dimensions: 71 x 28 x 71 mm
Application example: walk-in and display freezers.

Digital Thermostat with Defrost and Alarm Output


TC-940RiModel: TC-940Ri

Digital temperature controller which has four outputs: for defrost, fan, compressor and alarm. It starts the defrost cycles only when necessary, based on the evaporator temperature. Using it you can obtain a greater performance and lower power consumption.
This product is CE, UL and NSF certified.
Dimensions: 71x28x71 mm
Application example: walk-in and display freezers.


Digital Thermostat with Defrost and Alarm Output


TC-940RiL Plus Model: TC-940RiL Plus

One of the most versatile low temperature controller, it offers three operating modes: refrigeration; heating; automatic. The heating mode has been designed for applications where external (environment) temperature is lower than the evaporation temperature. Featuring four relay outputs, two temperature sensors, a digital input which can be programmed for door alarm, force defrost or economic setpoint, built-in buzzer and digital filter. With a powerful 16A Relay, commands directly up to 1HP compressors. In addition to these features, has On-demand defrost and a shutdown mode to inhibit all outputs including relay switches and alarms. The collection of residual refrigerant fluid before the defrost cycles reduces power consumption and enhances the system performance. The RS-485 serial communication port enables connection to our award-winning Sitrad software.
This product is UL and NSF certified.
Dimensions: 71x28x71 mm
