    Why is my CLIMAVENETA BRH 0071 FF not starting?
    • J
      Jackie FergusonAug 12, 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).

      Stephanie FloresAug 16, 2025
      High discharge pressure (greater than 32 bars) in your CLIMAVENETA Chiller can be caused by high outside water temperature. If this occurs, you should check the water temperature. It may also be due to a high utility water inlet temperature.

      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.
