For the installer
13.3.5 CTC EcoZenith i550 Pro - Wood boiler
The upper and lower connections are used for connecting a wood boiler to
the EcoZenith. This means that the flow from the wood boiler passes through
the entire EcoZenith. The flue gas sensor (B8) signals to the EcoZenith’s
control system that the wood is burning. Charging from the wood boiler
is controlled from the EcoZenith via a charge pump or by external charge
equipment, such as Laddomat 21. The charge pump in Laddomat 21 shall
be controlled from the wood boiler.

13.3.5.1 Pump controlled by flue gas temperature
The pump (G4) is controlled by the flue gas temperature, which is sensed by
the flue gas sensor. This pump can be used if, for example, a water-jacketed
stove or older combi-boiler with limited water volume is to be connected to
the EcoZenith. The pump starts when the flue gas sensor senses the set
temperature for wood boiler/stove operation. The pump has no on/off delay,
which means that if the water volume around the stove or boiler in question
is excessive, the circulation may initially cool down the EcoZenith.
