Important Notes for This Exact Model
- This is the short 130 mm version – perfect replacement for old UPS 15-50/60 pumps.
- No external PWM or signal connector (purely internal control).
- AUTOADAPT is active by default and is the recommended setting for 95 % of domestic heating systems.
- LED on the front box shows green flashing = normal operation.
