1. DESCRIPTION
Designed to better safeguard frozen products. TC-900e Log is equipped with 3 relays (Comp,
Defrost & Fan), 2 temperature sensors, 2 digital inputs, real-time clock, data logger and light intensity
sensor. A third temperature sensor can be connected to one of it’s digital input for either defrost
management of second evaporator; condenser temperature control or to activate economic set point.
Other salient features include hour-meter to clock the working hours of compressor for preventive
maintenance, internal buzzer, IP65 frontal, min-max temperature record, temperature sensor response
time control, fast freezing mode, tamper-proof function, control functions shutdown and RS485 serial
communication port for Sitrad real-time monitoring and management.
Product conforming to UL Inc. (United States and Canada) and NSF (United States).

ATTENTION
FOR INSTALLATIONS WHERE A SEALING IS REQUIRED TO AVOID LIQUID CONTACT, THE CUT FOR THE CONTROLLER MUST BE OF
70,5X29mm MAXIMUM. THE SIDE LOCKS MUST BE FIXED SO IT PRESSES THE RUBBER SEALING AVOIDING
INFILTRATION BETWEEN THE CUT AND THE CONTROLLER.
IMPORTANT
SCREWDRIVER SLOT 3/32''(2.4mm) FOR ADJUSTMENTS IN THE SIGNAL TERMINALS;
