The controller can be started by the ON/OFF key or through the auto start 
function. To turn on the controller, a +15 signal (ignition) is required. With that, 
the standby light will be on, allowing the visualization of the temperatures if the 
panel is on.

Note 1:

 If the standby light is off and the Power button is pressed, the standby 

light will come on and the panel can be turned on. However, if no 
communication is established, the product will return to sleep mode.

Note 2:

 emergency mode: if the control panel does not establish communication 

with the panel, after 1 minute the control panel starts to operate automatically.

Note 3:

 when turning on the panel, the Firmware versions of the ECU SU021 and 

the Panel SC2000 are informed respectively by the abbreviations SUV xx and 
SCV xx.

1- Status indication of the actuators;
2- Set-point temperature;
3- Outside Temperature;
4- Return Temperature.

When starting the panel, automatic mode is activated (the corresponding key is 
illuminated in amber color).
The auto mode activated indicates that the evaporator fan speed and the air 
recirculation function are operating in automatic mode, as well as the compres-
sor drive. Automatic mode is disabled when any of the following occurs:

 • AC key pressed disabling the compressor;
 • Changing the fan speed using the key.

Evaporator ventilation is controlled by the Set-point together with the suction 
and discharge pressure values. To maintain the appropriate pressure value for 
the operation and reach the defined Set-point.

1.4.2- Automatic Compressor

The compressor is activated according to the difference between the Set-point 
and the return temperature, values defined by the parameters (P68 and P69).
