5.1.3 Temperature Settings
Purpose of the unit is to keep the evaporator leaving water temperature as close as possible to a
pre-set value, called Active Setpoint. The Active Setpoint is calculated by the unit controller based
on the following parameters:
Available Modes (Cool, Cool w/Glycol, Ice)
Double setpoint input
Scheduler state
Cool/Ice LWT Setpoint
Setpoint Reset
Quiet Mode
Operation mode and LWT setpoint can also be set via network if the appropriate control source
has been selected.
5.1.3.1 LWT Setpoint Setting
Setpoint range is limited according to the selected operating mode. The controller includes two
setpoint in cooling mode (either standard cool or cool w/glycol) and one setpoint in ice mode, which
are activated according to Operating mode, Dual Setpoint or Scheduler selection.
If the Time Scheduler is enabled the Dual Setpoint input state will be ignored by the controller.
The table below lists the LWT Setpoint being activated according to the operation mode, the
double setpoint switch status and the scheduler state. The table also reports the defaults and the
range allowed for each setpoint.

The LWT setpoint can be overridden in case the setpoint reset (for details see chapter 5.1.6.3) or
the quiet mode are activated (see chapter 5.1.7.2).
Dual Setpoint, Setpoint Reset and Quiet Mode are not operational in Ice Mode.
5.1.3.2 Thermostat Control Settings
Thermostat control settings, see section 4.2.1, allow to set up the response to temperature
variations and the precision of the thermostat control. Default settings are valid for most
applications, however site specific conditions may require adjustments in order to have a smooth
and precise temperature control or a quicker response of the unit.
The control will start the first circuit if the controlled temperature is higher than the active setpoint
(AS) of at least a Start Up DT (SU) value. Once circuit capacity exceeds the Hi Ld Stg Up %
another circuit is switched on.
