Excess heat discharge
Active dissipation of excessive heat enables an external heat source to force
consumers (heating circuit, DHW storage tank, Hx pump) to draw excessive heat by
delivering a forced signal.
The parameter “Excessive heat draw“ can be used to determine for every consumer
whether or not it should take account of the "forced" signal, and hence whether or not
that consumer should participate in the dissipation of heat.
Local effect
When using LPB device address 0 or >1, excessive heat dissipation only acts on the
local consumers connected to the controller.
Central effect (LPB)
When using LPB device address = 1, excessive heat dissipation also acts on the
consumers connected to the other controllers in the same segment.
The distribution of excessive heat from segment 0 across other segments of the system
is not possible.
