Volute-Thermostat Fault

Hva betyr VLTS ?

This fault occurs when a digital input assigned to the volute/thermostat input (H1-0o = 88 or 89) is active, or if both volute/thermostat inputs are programmed simultaneously. Auto-restart is controlled by parameter L5-53.

• The digital input assigned to the volute/thermostat input (H1-0o = 88 or 89) is active
• Both volute/thermostat inputs are programmed simultaneously (H1-0o = 88 and 89)

1. 1

   Check the wiring to the volute or motor thermostat

2. 2

   Allow the volute or motor to cool

3. 3

   Program only one digital input to either H1-0o = 88 or H1-0o = 89

4. 4

   Review parameter L5-53 (Volute-TStat Retry Selection) for auto-restart settings
