4.6 Thermostatic Control
Thermostatic control settings, allows to set up the response to temperature variations. Default settings are valid for most
application, however plant specific conditions may require adjustments in order to have a smooth control or a quicker
response of the unit.
The control will start the first compressor if the controlled temperature is higher (Cool Mode) or lower (Heat Mode) than
the active setpoint of at least a Start Up DT value, whereas other compressors are started, step by step, if the controlled
temperature is higher (Cool Mode) or lower (Heat Mode) than the active setpoint (AS) of at least a Stage Up DT (SU)
value. Compressors stop if performed following same procedure looking to the parameters Stage Down DT and Shut
Down DT.

A qualitative example of compressors start-up sequence in cool mode operation is shown in the graph below.
When controlled temperature is within the dead band (DB) error from the active setpoint (AS), unit capacity will not be
changed.
If the leaving water temperature decreases below (Cool Mode) or rises above (Heat Mode) the active setpoint (AS), unit
capacity is adjusted to keep it stable. A further decreasing (Cool Mode) or increasing (Heat Mode) of the controlled
temperature of the Shut Down DT offset (SD) can cause circuit shutdown.
