If the compressor is blocked or showing a circuit alarm, check the specific alarm code on the display. Depending on the code, the reset method may be:
- A (Automatic reset): The alarm will clear automatically once the issue is resolved. - M (Manual reset): The alarm must be manually reset from the keypad after fixing the problem. - A/M (Automatic/manual reset): The first few occurrences reset automatically; later ones require manual reset. - S (Signal only): Informational, no reset needed.
Identify and resolve the cause, then reset the alarm if required.

If the CLIMAVENETA W3000 compressor is blocked by a compressor or circuit alarm, first eliminate the condition that triggered the alarm. Then, depending on the alarm type:
- If the alarm is manual reset (M), reset it from the keypad after resolving the issue. - If the alarm is automatic reset (A), it will reset itself once the issue is resolved. - If marked A/M, it resets automatically for the first few events, then requires manual reset. - For signal-only alarms (S), no reset is needed as they do not block operation.
Identify the specific alarm code to determine the reset type.

The “Setpoint menu” is used to set the setpoints for the various available functions. The “I/O menu” shows the status of the digital inputs and values read from the analogue inputs. It also shows the status of the digital outputs and the voltage supplied to the analogue outputs.

C0240111-04-05-GB 3.2.2 “MASTER-SLAVE” CONNECTION Intelligence is distributed instead in the “master-slave” connections. Suppose we have a unit with 4 cooling circuits: t he master card manages circuits 1 and 2 while the slave card manages circuits 3 and 4 . In this case, the additional card is not simply an input/output expansion, but is fully involved managing part of the unit.

The first operation to perform when a network is started up for the first time or an I/O card is replaced, is to activate the procedure for terminal configuration. This cannot be done with W3000 base. In this case, configure the terminals with a W3000 or W3000 compact terminal and then replace the display with a W3000 base.

C0240111-04-05-GB pLan address: Set the required address (e.g.: 1 ) increase To do this, press [UP] or [DOWN]; press [ENTER] to confirm. DOWN: decrease ENTER: save & exit An “empty” mask appears because the address of the keyboard is 0 and that of the card is (for example) 1; the two devices therefore cannot communicate.

C0240111-04-05-GB 3.4.4 CONFIGURING THE PLAN NETWORK CONFIGURING THE PLAN NETWORK (local): For each unit with an on-board keyboard, perform the following procedure to create a “locale” plan network: Display address Press [UP], [DOWN] and [ENTER] together and hold down until Setting..:00 the mask shown to the side appears.
Page 17
To connect several units together and remote control them, thereby forming a plan network (global), connect a remote keyboard controlling all the plans (local). The remove keyboard cannot be used with a W3000 base keyboard. If a W3000 keyboard is fitted to the unit, change it with a W3000 or W3000 compact.
Page 18
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”.
Page 19
C0240111-04-05-GB Disconnect the connector J10 connecting the keyboard on the unit with the card, and connect it to connector “A” of the “T” shunt (see figure 3.5). Connect connector J10 on the card to connector “B” of the “T” shunt. The correct configuration is shown in figure 3.5: Figure 3.5 : connecting the remote keyboard (for distances less than 200 metres) 2.

Questions and answers
The compressor is blocked a compressor or circuit alarm
If the compressor is blocked or showing a circuit alarm, check the specific alarm code on the display. Depending on the code, the reset method may be:
- A (Automatic reset): The alarm will clear automatically once the issue is resolved.
- M (Manual reset): The alarm must be manually reset from the keypad after fixing the problem.
- A/M (Automatic/manual reset): The first few occurrences reset automatically; later ones require manual reset.
- S (Signal only): Informational, no reset needed.
Identify and resolve the cause, then reset the alarm if required.

The compressor is blocked by a compressor or circuit alarm
If the CLIMAVENETA W3000 compressor is blocked by a compressor or circuit alarm, first eliminate the condition that triggered the alarm. Then, depending on the alarm type:
- If the alarm is manual reset (M), reset it from the keypad after resolving the issue.
- If the alarm is automatic reset (A), it will reset itself once the issue is resolved.
- If marked A/M, it resets automatically for the first few events, then requires manual reset.
- For signal-only alarms (S), no reset is needed as they do not block operation.
Identify the specific alarm code to determine the reset type.
