3. DHW with 3-way valve
Typically used when the water heater is
large, and when the surface coil is large.
The house is not supplied with heat while
producing hot water. The house must
therefore be able to manage without
heat for short periods during the winter
4. Weather Compensation and
solar thermal heating for the
DHW tank .
With an NBE flow box and 3-way weather
compensation vlave, the controller is able
to control the minimum boiler return
temperature on the system and adjust
the forwarding temperature to the house
based on an outdoor or indoor
temperature reference.
Note ! This setup requires the use of an
extension module to supply all the extra
outputs required in the installation.
A properly executed installation ensures that the system functions properly. Both national/local guidelines and requirements
must always be observed. The boiler can be installed on a pressurized system up to max 2.5 bar.
