If there is global network comprising just W3000 chillers , the W3000-compact can be used as a
remote keyboard. After configuring the various units (each with a different address in order not
to generate conflicts in the global network), connect the remote keyboard and repeat the
procedure.
In this case, the various machines of the network are switched by pressing [ESC] and [UP]
together.

If the plan network does not comprise just W3000 chillers , a 16-key keyboard must be used. In
this case, press [UNIT] to switch between one card and another. In this case, however, the
terminals must be given a special configuration as the 16-key keyboard is only recognised on
“terminal 3”.
The terminal configuration procedure remains the same up to point 6 of paragraph 3.4.5, after
which:
7) The remote keyboard can be configured even if the plan
network doe not comprise just W3000 chillers. Simply
define the keyboard addressed with 32 (N.B.: on
terminal 3) as Sh, i.e.: shared.

shunt
Let us analyse a vital component for connecting several
units in a network: the “T” shunt.
This is a shunt with phone connectors (called A,B,C in
figure 3.4b).
CONFIGURATION: For our purposes, configure
terminals J14 and J15 (see Figure 3.4b). There are
several pins in each terminal. Short pins 1 and 2 with a
jumper.

REMOTE KEYBOARD UP TO 200 metres:
To connect a remote keyboard, two “T” shunt cards must be used, one near the controller and the
other near the remote keyboard, configured as indicated above. The T shunt cards must be
connected together by terminals.
