Layout 2 (storage puffer management)
In this type of circuit, the storage puffer is managed by the stove due to a contact or immersion probe (optional) connected to the
back of the stove.
Below is shown the new "Stand-by" mode.
The operation is the same as for the basic layout except for the fact that in this layout, the boiler exchanges heat directly in the puffer;
when the temperature set is reached, the stove switches to ECO STOP mode and then restarts if the temperature drops below a
restart value (set by the installer upon testing).
Layout 3 (DHW boiler + storage puffer management)
The following layout combines the functions of the previous layouts and is recommended to stoves provided with a puffer without
internal coil preset for domestic hot water.
In this type of circuit, the boiler is managed by the stove due to a contact or immersion probe (optional) to be connected to the back
of the stove. The same applies to the control of the puffer that is provided by the thermostove through a contact or immersion probe
(not supplied) connected directly to the back of the stove.
Below is shown the new "Stand-by" mode.
The operation is the same as for the basic layout except for the fact that in this layout, the boiler exchanges heat directly in the boiler
(priority); when the temperature set is reached, the 3-way valve changes its position and the boiler starts exchanging heat within the
puffer. When the set temperature is reached, the stove enters in ECO STOP mode; it restarts if the temperature drops below a restart
value (set by the installer upon testing).
The 3-way valve is directed again into the boiler when:
- there is a request from the Boiler;
- there is a requested from the flow switch (optional, if connected).
The stove restarts from Eco-stop or Stand by mode according to storage puffer requests or boiler requests.
By setting the SUMMER function, the 3-way valve remains fixed in a single position, enabling the release of heat output
by the stove exclusively inside the boiler. As soon as this condition is reached, the stove switches to ECO STOP mode.
