🚨 Winter Tip for Truma CombiNeo Owners 🚨
When temperatures drop, your CombiNeo 2-in-1 heating and hot water system needs a little warm‑up before delivering hot water.
👉 If you go straight for hot water, you might see error W429H: “Water temperature at cold water connection too low. Water heating not available.”
✅ Quick Fix:
Run the appliance in room heating mode for a few minutes.
Once the inlet water reaches at least 8 °C, hot water will flow normally.
Stay cozy, avoid the frost error, and keep your CombiNeo heater running smoothly this winter ❄️🔥
