Peculiarities if a domestic hot water cylinder
is connected
Example 1
If a DHW cylinder is connected directly to the boiler,
note that:
In Installation Assistant Menu
A5
:
– with a boiler, the
Preference
parameter or
– with a cascade, the
Rev. seq. control
parameter
is always set to
Yes
. Only in this way can trouble-free
operation be guaranteed.
This does not apply to additional reconfigured hot water
circuits which are incorporated after the low-loss hea-
der.
The heating system consists of:
1 heat source
(e.g. wall mounted gas boiler, connection via eBUS)
1 DHW cylinder
1 uncontrolled heating circuit
(direct circuit, control via remote control device)
2 controlled heating circuits
(2 underfloor circuits, control via remote control
devices)
