In this menu, up to 2 heating demands can be activated and adjusted.
Activated demands will be available for selection in the output alloca-
tion channels of the backup heating in heating circuits and heating op-
tional functions. This way, several heating circuits and optional functions
can demand the same heat source.
Every demand can be carried out by means of a relay and/or a 0-10 V output.
If both the Relay and the 0-10 V option are activated, the demand will use both
outputs in parallel.
Relay option
If the Relay option is activated, the sub-menu Relay appears, in which a relay can
be allocated to the demand.
The options Boiler protection min and Boiler protection max can be acti-
vated for the demand via a relay, allowing temperature-dependent control of the
boiler demand. For this purpose, a boiler sensor (Sensor Boiler) is required.
The Boiler pr. min option is used for protecting an older type boiler against
cooling. If the temperature falls below the adjusted minimum temperature, the
allocated relay is energised until the minimum temperature is exceeded by 2 K.
The Boiler pr. max option is used for protecting an older type boiler against
overheating. If the adjusted maximum temperature is exceeded, the allocated relay
is switched off until the temperature falls by 2 K below the maximum temperature.
