5.1.1 Control Source
This function allows to select which source should be used for unit control. The following sources
are available:
Local
Unit is enabled by local switches placed into the switchbox, chiller mode (cool, cool w/glycol, ice), LWT setpoint and capacity
limit are determined by local settings in the HMI.
Network
Unit is enable by a remote switch, chiller mode, LWT setpoint and capacity limit are determined by an external BMS. This
function requires:
Remote enable connection to a BMS (unit on/off switch must be in remote)
Communication module and its connection to a BMS.
More parameters about network control can be found in 4.2.2.
5.1.2 Available Mode Setting
The following operating modes can be selected through the Available modes menu 4.7:
Cool
Set if chilled water temperature up to 4°C is required. No glycol is generally needed in the water circuit, unless ambient
temperature may reach low values.
Cool
w/Glycol
Set if chilled water temperature below 4°C is required. This operation requires proper glycol/water mixture in the
evaporator water circuit.
Ice
Set if ice storage is required. The application requires the compressors to operate at full load until the ice bank is
completed, and then to stop for at least 12 hours. In this mode the compressor(s) will not operate at part load, but will
work only in on/off mode.
Cool/Ice
w/Glycol
Set in case a dual cool/ice mode is required. This setting implies an operation with double setpoint which is activated
through a customer supplied switch, according to the following logic:
Switch OFF: The chiller will work in cooling mode with the Cool LWT 1 being as the Active Setpoint.
Switch ON: The chiller will work in ice mode with the Ice LWT as the Active Setpoint.
Test
Enables the Manual Control of the unit. The manual test feature helps in debugging and checking the operational status
of sensors and acutators. This feature is accessible only with the maintenance password in the main menu. To activate
the test feature is required to disable the Unit from the Q0 switch and change the available mode to Test (see
section5.2.1).
