Full Gauge TC-900 E Operation Manual

1. DESCRIPTION
For frozen products, it automates the defrost processes according to the need of installation (smart
defrost). The ambient temperature control has a normal setpoint and an economic setpoint, apart from
the fast freezing function and alarm functions indicating open door. Its 16A relay directly controls
compressors of up to 1HP and its defrost output has a current capacity of 10A.
It also features a digital filter, intended to simulate a mass increase in the ambient sensor (S1), thus
increasing its response time (thermal inertia) and avoiding unnecessary drives of the compressor. It also
includes a smart key, lock system and a control functions shutdown mode.
To drive inductive loads (motors and pumps) of up to 2HP, use the

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
