- T3 ? ow sensor ground connection
- T3 ? ow sensor failure
- Controller failure
Check the data in Error mode. Boiler data during error:
1 Error = 14
2 Operational status = 00
3 Flow temp. = -22
4 Return temp. = xx*
5 kW burner = 00**
6 % pomp = xx*
* = variable values
**= x3415=BTU/hr
A temperature of - 36 is displayed at position 3. Check the wiring and/or measure the resistance of the ? ow sensor. The resistance should be approx. 12 kOhm at 77°F. (See table in Appendix B)
If necessary, replace the ?ow sensor
