Brine Temperature Difference Incorrect (2-5 °C) — Brine flow imbalance

What does Brine Temperature Difference Incorrect mean?

The temperature difference between brine out (BT11) and brine in (BT10) is not within the optimal range of 2-5 °C, indicating an incorrect flow in the brine system.

• Brine pump speed is set incorrectly.
• Low temperature difference indicates a high brine flow.
• High temperature difference indicates a low brine flow.

Click steps to track your progress.

1. 1

   Check the temperature values for brine out (BT11) and brine in (BT10) in menu 3.1, 'service info'.

2. 2

   Observe the temperature difference 5 minutes after the compressor starts.

3. 3

   Adjust the speed of the brine pump (GP2) until the temperature difference is consistently between 2-5 °C.

4. 4

   Refer to the pump capacity diagrams in the manual to correctly set the brine pump speed for your F1245 model (e.g., 5 kW, 6 kW, 8 kW, 10 kW, 12 kW).
