machine codes during operation, see “ON-BOARD ELECTRONICS” on page 30, and

“TABLE OF OPERATING CODES “ on page 83.

Figure 1 – The S61 electronic circuit board. The Display, Encoder and CAN-BUS Port

Programming, control and monitoring of the ACF are done through the display and the

circuit board encoder; the encoder is the knob shown in Figure 1, letter ”B”, which can be

turned or pushed.

For its use, go to the “Display and Knob (encoder)” on page 32. The CAN BUS port allows

one or more ACF’s to be connected to a Direct Digital Controller (DDC).

The DDC, available as an option, monitors and controls each ACF in a more precise

manner, and can support and manage up to 16 chillers on a water circuit, regulating start-

up in relation to the requested need.

Figure 2 – Direct Digital Controller (DDC)

For the connection of a DDC to the ACF, go to the “APPLIANCE PUMP CONTROL”

paragraph on page 55.

The ACF’s include the following:

• cooling circuit in steel, treated on the outside with epoxy paint;

• multigas pre-mixing burner equipped with ignition and flame detection managed by

an electronic control unit;

KEY

A 4 digit DISPLAY for the visualization of the data and operational codes

B KNOB (encoder) for navigating and selecting of operational data

C CAN PORT for the connection of the CAN-BUS network cable
