Domestic hot water management
in the modular system
Every module of the system can pro-
duce domestic hot water.

It is necessary for each module dedi-
cated to producing DHW to be
equipped with 3-way valve installed
as an accessory.

Every module must have its own cir-
culation pump and its own domestic
hot water storage (responsibility of the
Customer).

The DHW pumping unit will be man-
aged directly by the unit dedicated to
DHW using a free contact.

DHW production only takes place if
the DHW storage temperature is
above a minimum threshold (See dia-
gram). The minimum temperature
threshold varies based on the external
temperature. In order to avoid that it
falls under the minimum temperature,
it is best to install a backup electric
heater on the DHW storage

Domestic hot water management is of
priority compared to the system.
If the system is satisfied (unit off):
When the temperature probe (T5), sup-
plied by ELCO and positioned inside
the storage calls for production of DHW,
the unit dedicated to DHW activates,
changing the set-point from set system
to set DHW and diverts the water flow
through the built-in 3-way valve. The
unit will remain active until the DHW set
-point has been satisfied, then it will
shut-off.
If the system has a request (unit is on):
When the temperature probe (T5)
sends a request for production of DHW,
the unit dedicated to DHW, which is
already active for the system stops, the
cycle changes and if producing cooled
water, the set-point changes from set
system to set DHW and diverts the wa-
ter flow through the built-in 3-way valve.
The unit will remain active until the
DHW set-point has been satisfied, then
it will return to producing the system
