different partial loads. This index characterizes the seasonal behaviour of a chiller with Adaptive Function Plus better than the traditional ESEER index.
,2. High precision: "Precision"
with standard return control.
Therefore, the "Precision" option guarantees precision and reliability in all applications that require a controller that guarantees a more accurate
constant water supply temperature, and where particular humidity control is required. However, it is always recommended to use a storage tank
with greater system water content in process applications to guarantee high system thermal inertia.
s
Virtual Tank: guaranteed reliability, even with water only in the pipes
Low water content in the system can cause chiller/heat pump units to work inconsistently, causing system instability and poor performance. Thanks to the
Virtual Tank function, this is no longer a problem. The unit can operate in systems with just 2 litres/kW in the pipes given that the control is able to compen-
