  Robert AguirreAug 15, 2025
  If your CLIMAVENETA Heat Pump unit doesn't start, first check for a power failure by verifying the voltage and inspecting the safety systems upstream of the appliance. If power is present, the issue might be a faulty contactor coil, HSW15 controller fault, or a faulty start-up capacitor (if featured). In such cases, replace the component. Other potential causes include a faulty compressor or reversed phases (for three-phase units only).

Why do protection devices trip and shut down the compressor in my CLIMAVENETA Heat Pump?
- D
  Denise PerezAug 18, 2025
  If the protection devices trip and shut down the compressor in your CLIMAVENETA Heat Pump, check for excessive discharge pressure, low suction pressure, or low voltage. Also, ensure that electrical connections are sufficiently tight. Operation outside permitted limits could also be the cause.
