7.9 Zone pump modules (ZonePumpModule, modules
29 to 34)
A zone pump module is available for each of the six possible
zone pumps. Its data type is 10, non-standard.
* Hydro/Control MPC-E, Multi-E/TPED model H and MAGNA3-
D.
** For Hydro Multi-E this indicates the state commanded by the
Hydro Multi-E control. A local override command, for example
stop, is not indicated by this bit.
*** Hydro/Control MPC-E, Multi-E, TPED and MAGNA3-D.
