4.3 Heating Related – Group 1: {“HGOM”:
This group identifies heating related information and is sent by the N-BW2 as part of the status information
reported when heating is the current operating mode of the Networker System.
Under the heating operating mode, there exists two very distinct modes of operation:
1)
Single Set Point Operation (Standard)
In this mode of operation one set point temperature defines the operation of the system even if the
system is zoned.
2)
Multi Set Point Operation (Zone Plus)
In this mode of operation the heating system is zoned and each zone that exists in the system can have
its own operating characteristics. For example one zone can be under manual control while another is
under schedule control both with different set point temperatures defined.
The
{“SYST”: {“CFG”: {“MTSP”: “$” } } }
tag indicates the current operating mode the system is in. The
commands required for these two distinct modes differ slightly so they are described in separate sections
For example the following command alters the set point temperature of Zone B to 23°C when operating under
heating mode in a multi set point system:
{“HGOM”: {“ZBO”: {“SP”: “23” } } }
For a single set point system the equivalent command would be:
{“HGOM”: {“GSO”: {“SP”: “23” } } }
Note that when the schedule setup is being accessed the mode switch
{“SYST”: {“OSS”: {“M”: “$” } } }
will
not be executed until the schedule setup is exited.
