6.3 Air heating apparatus
Function ECO-L
The air heaters are supplied with the maximum supply temperature by the boiler
storage system. The blowers are controlled by the customer's on-site switches or
controllers.
The hot water flow rate is controlled by the return flow temperature (flow control) and
this in turn adapts the heat output of the air heater.
This results in an optimised storage stratification with a higher temperature maintained
in the storage feed over a longer period. The heating times (day and week program)
can be adjusted via the integrated timer.
