7.3.5 Boiler Release
When setting the system selection, the parameter “Boilerlaunch in av” is
preset to enable an external floating release or start contact.
Boilerlaunch in av YES
This is set if boiler release input is available.
As long as the contact is closed, the controls operate
according to the specified parameters. If the external
contact is open, the boiler loses the release and
follows the shutdown procedure.
(e.g. flue gas thermostat of a supply boiler)
Boilerlaunch in av NO
This is set if there is a boiler start input or no layout.
As long as the contact is open, the controls operate
according to the specified parameters. If the external
contact is closed, starts the boiler and works in
continuous operation. (e.g. heat requirements of a
heating fan)
If the boiler is released or started by the parameter, it goes at least
to “Heating” status, even if meanwhile the signal has stopped.
When this has been carried out, the boiler follows the shutdown
procedure.
Note: Do not set any wire handle Continuous operation!
