6.2 Utility water heater
Function ECO-B1
If the utility water temperature drops then this is re-heated by the boiler or the heat
storage via the integrated heat exchanger. An appropriate temperature differential
(selectable between differential temperature or fixed preset temperature) is a
prerequisite.
The heating times (day and week program) can be adjusted via the integrated timer.
Function ECO-B2
If the utility water temperature drops then this is re-heated by the boiler or the heat
storage via the integrated heat exchanger. An appropriate temperature differential
(selectable between differential temperature or fixed preset temperature) is a
prerequisite.
The hot water flow rate is controlled by the return temperature (flow control). 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.
