(*) High-temperature regime means 60 °C return temperature at heater inlet and 80 °C feed temperature at heater outlet.
(**) Low temperature means for condensing boilers 30 °C, for low-temperature boilers 37 °C and for other heaters 50 °C return temperature (at heater
inlet).
2.13 PUMP DUTY
Linea ONE boilers are fitted with a variable speed circulation unit
that is already connected up in terms of plumbing and electrics, and
the usable performance it provides is shown in the graph.
The boilers are fitted with an anti-blocking system that starts an
operating cycle every 24 hours when not used, irrespective of the
position of the function selector.
The "anti-blocking" function is only active when the electrical power
supply to the boiler is on.
Operating the circulation system without any water is strictly forbid-
den.

VARIABLE SPEED CIRCULATION UNIT
The modulating circulating function is only active for the heating func-
tion. When switching the three ways on the plate heat exchanger,
the circulation unit is set at maximum speed. The modulating
circulation function applies only to the boiler circulation unit and
not to circulation units on any external devices connected to it (e.g.
booster circulation unit).
Any of 4 operating modes can be chosen, depending on situations
and the type of plant.
