An example of a hydraulic diagram for mixed temperature systems is given below. A
mixing system as SILE TBA/TBA-M, must be used. The boiler will operate at the best
temperature for optimising thermal comfort and energy performance.

The remote control with mixed systems as described above must be correctly configured
in the electronic board. This is done by setting DIP switch no. 4 to ON (see. Fig. 4 Page
12) to control the sanitary hot water temperature and reset the boiler (no more than five
attempts after which the boiler must be reset) but losing the programmable thermostat
function that will be implemented by the zone thermostats.
The boiler feed temperature in the heating function is given by the boiler control panel.
In this case, use of the external sensor connected to the boiler PCB is also possible as
shown in Figure 4.
2.9 Filling the CH circuit (for remote tank)
Open the cold water shutoff cock located in the system; open the hot water try cock
on the system leave it open for the filling circuit and sanitary exchanger.
2.10 Filling heating circuit
To fill the boiler move three way valve in manual position. Turn on slowly the loading tap
(fig. 1 pos.18) to carry the pressure system, indicated in water gauge, on about 1 bar
value and turn off. Check that the vent located on circulator have cap loose, and then
operate the circulator to remove the air in the circuit how follows: turn repeatedly the
“function selector” (fig. 1 pos. 36) from the off position to the winter position until the total
purge air. Complete the purging of the boiler and system, check the charge pressure.
