# The entire setup consists of:
|
|
#
|
|
# - Furnace that burns oil and produces heat.
|
|
# It only burns when necessary, i.e. some of the
|
|
# controlled temperatures are below set values.
|
|
#
|
|
# r/o: active (burning) / inactive (idle).
|
|
#
|
|
# - Boiler which keeps hot water (but can also heat it
|
|
# electrically, albeit turned on/off at the mains).
|
|
#
|
|
# r/o: internal boiler temperature.
|
|
# r/o: outgoing (top) water pipe temperature.
|
|
#
|
|
# - Floor heating which is technically controlled
|
|
# via furnace control panel, but is a separate system.
|
|
# It also includes two radiators (which are normally off),
|
|
# but due to ambiguity of "heating" meaning both the process
|
|
# and a house-warming system, we opt in for this specific
|
|
# "floor heating" term.
|
|
#
|
|
# r/o: flow temperature.
|
|
# r/o: active (flow temperature controlled) / inactive (idle).
|
|
# r/w: intent (instruct the flow to start heating).
