Why is my CLIMAVENETA Chiller not starting?

  fwardAug 13, 2025
  Your CLIMAVENETA Chiller might not be starting due to several reasons. There could be no voltage, in which case you should check the presence of voltage and safety systems upstream of the appliance. Alternatively, a contactor coil, the HSW12 controller, or the start-up capacitor (if featured) might be faulty, requiring component replacement. Other potential causes include a faulty compressor or reversed phases (for three-phase units).

  Low suction pressure (less than 4 bars) in a CLIMAVENETA Chiller can stem from several factors. These include a low utility water inlet temperature, a low outside water inlet temperature, or a faulty or blocked thermostatic expansion valve, so you should check these components. It may also be caused by a blocked water filter or a blocked plate heat exchanger.
