1. DESCRIPTION
The TC970e Log and TC970e Log Faston are eletronic controllers for kkkkkkk +609 gE
refrigeration of freezers, beverage displays, islands and refrigerated counters.
These controllers can activate the refrigeration, defrost, fan and lighting system, and have up to two
digital inputs and two main sensors, one for room temperature and another that, fized to the evaporator,
controls the end of the defrost and the return of the fans. They also allow the inclusion of a third sensor,
which can be used to activate the economic setpoint, control the condenser or in the second evaporator
and a fourth sensor for various monitoring.
The line includes the control of VCC - Variable Capacity Compressors and VSF - Variable EHIgfM
Speed Fans. The controllers provide a series of benefits to the cooling system, such as: SadSBI
reduced energy consumption, less temperature fluctuation, greater speed in reaching the desired
temperature. From the configuration of its parameters it is possible to make the controller compatible
with the main brands of variable compressors on the market. For better use of energy, ventilation can be
controlled during the compressor off cycle and use Smooth Defrost, a defrosting technique that reduces
the final temperature of the electrical resistance and the amount of heat emitted.
The room temperature control has a normal setpoint and an economy setpoint, in addition to the fast
freezing functionality, alarm functions and specific keys to activate / deactivate the economy mode and
turn the lamp on/off.
They have a serial communication output for integration with Sitrad, an internal real-time clock that
allows the programming of defrost and lighting events, an intelligent function blocking system, an
internal buzzer, control of external pressure switches, an hour meter for compressor maintenance,
digital filter to simulate a moment of mass in the room temperature sensor, shutdown mode of control
functions and internal memory (datalogger) for storing the temperature value in periods of time
determined by the user, temperature variation and the output states. They also allow the monitoring of
HACCP - Hazard Analysis and Critical Control Points through records in the memory of the temperature
alarm, open door and power failure controllers.
2. SAFETY RECOMMENDATIONS
- Make sure you know the correct way to install the controller;
- Make sure that the power supply is turned off and that it is not going to turn on during the installation of
the controller;
- Read this manual before installing and using the controller;
- Use appropriate Personal Protective Equipment (PPE);
- Where it will be used in areas subject to splashing water, such as refrigerated counters, install the
protective film that comes with the controller;
- For protection under more critical conditions, we recommend the Ecase cover, which we offer as an
options (sold separately) ;
- The installation procedures must be carried out by a competent engineer, with regard to current
regulations.
