functions:
1. DESCRIPTION
2. APPLICATION
3. TECHNICAL SPECIFICATIONS
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 eTC-900 2HP.

To access the setpoints setup menu press / for 2 seconds. The message [SP,,] will appear on the
display followed by the normal setpoint set value. Use the > or< to modify the value and confirm by
pressing /. Immediately, the message [SP-e] appears indicating the setting of the economic
setpoint. Again, use the > or < keys to modify the value and confirm by pressing /. Finally, the
[----] indication signals the setup completion. The setpoints can also be adjusted individually in the
quick access menu.
