consumption
It is compulsory that each installation is equipped with a back end protection valve (thermal shock valve)to permit uniform
temperatures at the start up of the boiler or thermo-stove and to avoid condensation inside the combustion chamber.
Bronpi approved Distributors can supply such a valve.
(In case that the fitter chooses install a buffer tank he must connect the remote thermostat to control this tank to the terminals at
the rear of the boiler marked "Termos ambiente (room thermostat)" AND also change the setting/parameter in the technical menu
M-10-4-13 from "2" to "1". SEE SECTION below marked EXTERNAL COMMAND CONNECTIONS. That is in the case that we want
the boiler or thermostove to continue operating according to the water temperature.
• SANITARY HOT WATER TANK (SHW)
If the boiler or thermo-stove has been connected with a SHW tank we have to consider the following requirements:
- The boiler can only control one SHW tank; in other case it is not guaranteed the correct operation of the boiler in case of replacing this
system for any alternative one.
- The SHW tank must be equipped with a thermostat that measures the temperature inside the tank and controls the exchange water
intake if necessary.
- In warm seasons (summer or Autumn) where it is not necessary to simultaneously use the heating and SHW and only the SHW is
necessary we need to programme the display that the system works in "Summer" mode. Then the boiler or thermo-stove will only work
when there is a demand from the SHW tank.
- We have to note that when the boiler or thermo-stove works in "Winter" mode the SHW system has preference over the heating circuit.
The installer or technical service engineer, during commissioning of the boiler, has to choose the power (1, 2, 3, 4 or 5 in
MENU 10) for the boiler under the SHW demand, depending on the ability of the exchanger. This setting defines the default
power used under SHW demand, once SHW water reaches the desired temperature, the boiler will then take into account the
corresponding power setting programmed for Heating water.. Below you can see the messages shown on the display when the
SHW heating system works (see drawings D12 and D13).

• EXTERNAL INPUT/COMMAND CONNECTIONS
Both boilers and thermo-stoves are equipped with a series of connectors, at the
rear, to facilitate the connection with different controllers (see drawing D14).
