LWTs:
water outlet temperature from the source-side heat exchanger
LWTu:
water outlet temperature from the user-side heat exchanger
LWTr:
water outlet temperature from the recovery exchanger
BK:
For LWTu lower or equal to +3°C, it is mandatory to fit the "Brine Kit" accessory
For LWTu below +5°C, it is compulsory to use suitable percentages of antifreeze additives (glycols) to prevent ice formation in the
exchanger.
The inlet and outlet temperatures of the user-side exchanger must be given on ordering to allow correct setting of the alarm parame

ters and verification of the sizing of the expansion valve.
The cooling set point can then be changed by the customer in an interval that, compared to the set point given on ordering, ranges
from -1K up to the maximum temperature allowed by the above-stated operating limits.
The unit will be optimized to work at the set point temperatures given on ordering. For different set points, the cooling capacity pro

vided and the level of efficiency of the machine could decrease and move away from these conditions.
