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

Mr. Anderson
April 15, 2025

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 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.

  • 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”.
