panels, circulation may be started to reduce the risk of

frost damage.

9.5.2.8 Wood Boiler

Start at ﬂue gas temp °C 100 (70...250)

This menu is used to deﬁne the ﬂue gas temperature

(sensor B8) at which the system is required to enter

wood operation status and the heat pump(s) is required

to be stopped.

Wood operation is activated when the ﬂue gas

temperature exceeds the set value in this menu and

the temperature in the EcoZenith’s lower tank is equal

to or above its reference value (setpoint). When wood

operation is active, the heat pump or additional heat are

not used for heating the EcoZenith. Wood operation is

deactivated when the ﬂue gas temperature drops below

the set value in this menu.
