Incorrect Coding 015 - Boiler firing without circulation pump or DHW pump not energized

What does Incorrect 015 coding mean?

Changing coding address 015 from its factory default can cause significant operational problems. For models 6-24C/6-24/8-32, changing to 015:001 results in the boiler firing without the circulation pump and solenoid valve. For models 11-44/15-60, changing to 015:000 results in the DHW pump not being energized. This may also lead to fault 02.

1. 1

   For models 6-24C, 6-24, 8-32, ensure coding address 015 is set to 015:000.

2. 2

   For models 11-44, 15-60, ensure coding address 015 is set to 015:001.

3. 3

   After making any changes, power cycle the boiler (power ON/OFF) for the new settings to take effect.

4. 4

   If fault 02 appears, address coding 015 first as a potential cause.
