TC-970E Log +ECO Faston
Description
This controller acts in the refrigeration, heating, or automatic modes, and it is compatible with fixed speed compressors of the ON/OFF type (relay output) or variable capacity ones (Variable Capacity Compressor – VCC). It has a frequency output from 0 to 300 Hz or voltage output from 0 to 10 Vdc compatible with the leading brands in the market, as well as enabling the control of Variable Speed Fans (VSF).
The PID logic promotes better system performance and stability, and the real-time internal clock for scheduling defrost actions and Economic SetPoint actions on weekdays and weekends.
It has these functions: Fast Freezing, for quick freezing, and Smooth Defrost for a softer and more economical defrosting; digital filters, to simulate a higher mass load in the environment sensor (S1), delaying the response time (thermal inertia) and avoiding unnecessary compressor actions.
Its two digital inputs allow for the connection of a third sensor* to control the door’s temperature, a second evaporator or condenser; a fourth sensor to show the insufflation temperature; monitor the door opening, high or low-pressure gauge signal; action of Economic SetPoint, defrost, combined defrost, lighting, Fast Freezing; external alarm or control’s turn-off. The low-voltage version (12/24V) has a voltage monitor.
The new fast link connection system Faston of this product have increased the productivity in the manufacturing lines.

WHAT ARE VCCs?
In traditional applications of refrigeration, it is common the variation of the load demand on the compressor. The operation frequency control of a variable capacity compressor adapts its use to the real demand. Thus, the compressor works at a low speed most of the times, minimizing the power consumption.
The main benefits of this technology are reduction of the power consumption, quicker refrigeration and better conservation of the stored goods, since it keeps the internal temperature of the equipment stable.
HOW DOES THE TC-970E Log +ECO WORKS IN VCCs?
Due to its exclusive PID controller, it warrants the efficiency of the frequency output from 0 to 300 Hz or voltage output from 0 to 10 Vdc variable capacity compressors, with a configurable frequency depending on the VCC brand and model.
