7.5 Direct bus control of pumps (ControlPumps,
module 50)
This module is only available for CU 352.
With this module it is possible to individually force each of the six
zone pumps, the pilot pump and the backup pump to stop. Its
data type is 5, unsigned 8 bit.
The present auto mode status of each pump can be read from AutoModePumps (module 51).
7.6 Change feedback sensor type
(SelectFeedbackSensor module 57)
This module is only available for CU 352.
With this module it is possible to dynamically change the
feedback sensor type between a flow sensor and a pressure
sensor. For the setting to work, CU 352 must in advance be
configured to use a pressure sensor on one of its analogue inputs
and a flow sensor on another one.
The data type is 5, unsigned 8 bit.
