If the water return temperature is less than
about 55°C, the combustion products con-
dense, further increasing the efficiency of
thermal exchange.
Regulation of the external
sensor (fig. 26/a)
If an external sensor is installed, the value
of the output temperature is automatically
chosen by the system, which quickly adjusts
the of flow temperature on the basis of the
external temperature.
If you wish to change the value of the tem-
perature, increasing or decreasing that cal-
culated automatically by the electronic
card, proceed as indicated in the preceding
paragraph.
The level of various correction of a value of
temperature proportional calculated. The

electricity supply, by switching off the main
switch of the system, and to close the gas
tap and, if low temperatures are expected,
to completely empty the hydraulic circuits
to avoid pipes being broken by the forma-
tion of ice in the pipes.
