Note:
The above schematic is purely indicative. The boiler’s main control board provides a programmable
output "QX1" that can be used to control any of the following devices:
- Solar circuit pump PS (5890 = solar circuit pump Q5)
Solar controller parameters: 5093=yes; 5730=sensor; 5930=collector sensor B6; 5931=B31
- DHW recirculation pump PR (5890=DHW recirculation pump Q4)
DHW recirculation parameters: 5730=sensor; 5930=B39
- Direct CH circuit pump PD (5890=CH pump CRP Q20).
Expansion kit 20011194 / 20102310 must be installed before all three functions can be available together.
