4 WORKING WITH THIS UNIT
This section contains a guide on how to deal with the everyday usage of the unit. Next sections describe how to perform
routine tasks on the unit, such as:
• Unit Setup
• Unit/Circuit start-up
• Alarm handling
• BMS Control
• Battery replacement
4.1 Unit Setup
Before starting up the unit, some basic settings need to be set by the customer according to the application.
• Control Source
• Available Modes
• Temperature Settings
• Alarm Settings
• Pump Settings
• Power Conservation
• Date/Time
• Scheduler
4.1.1 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.
4.1.2 Operating Mode
The following operating modes can be selected through the Available modes setpoint.
Mode
Description
Cool
Set if only 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 only chilled water temperature below 4 °C is required. This operation requires proper
glycol/water mixture in the evaporator water circuit.
Cool/Ice
w/Glycol
Set in case only 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.
Ice w/Glycol
Set if only 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.
MultiPurpose
Set in case a contemporary cool/heat mode is required. This setting implies an operation with
double functioning,
• with the Cool LWT 1 as the cooling Active Setpoint and
• with the Heat LWT 1 as the heating Active Setpoint.
MultiPurpose
w/Glycol
Set in case a contemporary cool/heat mode is required. This setting implies an operation with
double functioning,
• with the Cool LWT 1 as the cooling Active Setpoint and
• with the Heat LWT 1 as the heating Active Setpoint.
MultiPurpose/Ice
w/Glycol
Set in case a contemporary cool/heat mode is required. This setting implies an operation with
double functioning,
• with the Ice LWT as the cooling Active Setpoint and
• with the Heat LWT 1 as the heating 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 actuators. 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 section 4.2.1).
