In manual control mode, the speed or nominal delivery head of p-c or
p-v operating mode of the pump is set via the 0-10 V input of the IF
Modules Stratos Ext.Off, Ext.Min and SBM. In this case, the control but-
ton is without function for entering the setpoint.
p-T control mode, control to temperature-dependent differential
pressure setpoint (Fig. 10). The current H
S
setpoint is displayed. This
control mode can only be activated using an IR operating and service
unit (accessory) or via the serial digital interface.
All settings at the module are disabled apart from fault acknowledge-
ment. Disabling is performed by the IR operating and service unit
(accessory). Adjustments and enabling can only be made using IR oper-
ating and service units (accessories).
The pump is operated via a serial data interface. The "On/Off" function
is not activated at the module. Only , , display position
and fault acknowledgement need to be set at the module. The IR oper-
ating and service unit (accessory) can be used to temporarily interrupt
operation at the interface (for checking, for reading out data). With cer-
tain IF Modules, the menu can be re-opened. (The menu can then still be
operated manually even though the module is connected) (see docu-
mentation of the IF Modules)
Pump is running as slave pump.
No change can be made at the display.
The double pump runs in efficiency-optimised peak load operation
(master + slave).
Double pump running in main/standby mode
(master or slave)
Appears on pumps with certain IF Modules (see documentation of IF
Modules) if a signal (sign) is sent from the building management system
to the pump.
The pump is set in the "US units" mode.
Fault-tolerant error matrix activated.
Heating operating mode (for faults, see Chapter 10)
Fault-tolerant error matrix deactivated.
Air-conditioning operating mode (for faults, see Chapter 10)
