5.5 - Water flow switch
The controller is configurable. The configuration depends on
the unit size and is made automatically at the start-up.
If the measured flow rate in the water loop is lower than the
configured flow rate, an alarm condition shuts off the unit.
5.7.1 - Active setpoint
Two setpoints can be selected. Usually, the second cooling
setpoint is used for unoccupied periods. Depending on the
current operation type, the active setpoint can be selected
by choosing the item in the table Status => Genunit, with the
volt-free user contacts, with network commands or with the
setpoint timer program (schedule 2).
The following tables summarise the possible selections
depending on the control types (local, remote or network)
and the following parameters:
•
Setpoint select in local control
: item “Setpoint select”
in the table Status => Genunit permits selection of the
active setpoint, if the unit is in local operating type.
•
Control contacts 2:
status of control contact 2.
•
Schedule 2 status:
schedule for setpoint selection.
5.7 - Control point
The control point represents the water temperature that the
unit must satisfy.
In cooling mode the evaporator outlet water is controlled by
default, but the evaporator inlet water can also be controlled
(requires a Service configuration modification).
In heating mode the condenser outlet water is controlled by
default, but the condenser inlet water can also be controlled
(requires a Service configuration modification).

5.6 - Heating/cooling selection
For units configured in the heat pump mode, heating/cooling
selection can be controlled in various ways, depending on
the active operating type:
•
locally at the unit using the HC_SEL item in the
GENUNIT table,
•
remotely via the heating/cooling selection contact, if
the unit is in the Remote mode operating type,
•
via a CCN or BACnet/IP (option) network command,
if the unit is in the network operating type.
