4�2 Secondary separator kit
4�2�1 Secondary circulation pump P2
The secondary circulation pump P2 is driven exclusively by
the input for the TA section, "DHW only" (even with the con-
troller in stand-by).
The device uses a wet rotor high efficiency circulation pump
suited for all heating and cooling systems with a tempera-
ture range from -10 °C to +110 °C which by means of specific
syn-chronous motors - with permanent magnet rotor con-
trolled by inverter in class A - guarantee up to 80% of energy
saving with respect to standard pumps.
The control electronics automatically adapt operation to the
changing conditions in the hydraulic system.
A regulator is present on the front of the pump body to se-
lect the maximum head according to the actual needs of the
system and to select:

The maximum head value setting of the P2 heating/cooling
system pump must be made with the compressor at 100%
all distribution valves open and the devices on checking the
thermal gradient between system delivery and return lines,
which must be comprised between 4 - 7 °C.
Set a lower circulator speed if the thermal gradient is lower
than 4 °C. On the contrary, if the thermal gradient is higher
than 7 °C check the opening of all valves on the system and
then add an external pump to increase the water flow rate.
