Config
When manual mode is used, the C7000 control is suspended.
The manual mode menu consists of two columns of parameters which are decisive for
its operation.
In the first column (entitled en.), you activate manual mode for the listed component by
setting the parameter to "1".
The second column (entitled STATE) displays the actual state of the component. Once
➋
you have activated manual mode in the first column, you can switch the component on
and off here.
For proportionally-regulated components, you can enter a percentage in the second
column (entitled VALUE) which corresponds to a degree of openness for a valve or a
capacity/speed for other components.
Components that can have either proportional or on/off control have both columns
(STATE and VALUE). But only the applicable parameter takes effect.
For test purposes, sensors and auxiliary alarms can also be simulated in manual mode.
You specify the values for this so that you can test the controller's behavior.
When leaving the manual mode level (if the "Components" menu is reached again),
manual mode is terminated for each component and the controller takes over control.
In this window, you can set the air conditioning technology functions for operation with
an uninterruptible power supply (UPS).
If the controller receives a signal for UPS operation at the corresponding digital input,
all functions that have been activated in the window using "1" are approved. On the
contrary, functions marked with "0" are deactivated.
Ensure that the fan speed can also been reduced to a preset value during UPS operation.
