Secondary boiler start delay
If there is a requirement from the heating circuit or DHW
tank and the buffer tank or boiler has insufficient
temperature, the secondary boiler starts after the specified
delay time set here.
Disable startup delay in case of fault?
Indicates whether the startup delay is ignored in the event
of a boiler fault and whether the standby boiler is activated
immediately on request.
Deactivate startup delay when boiler is switched off?
Indicates whether the startup delay is ignored when the
boiler is switched off and whether the standby boiler is
activated immediately on request.
Secondary boiler start, if buffer tank top temperature is
below
If the temperature in the top part of the buffer tank falls
below the specified value, the secondary boiler is started
once the set duration has elapsed.
Start standby boiler only after storage tank top
Standby boiler enabled after temperature decreases below
minimum temperature on top storage tank. No consumers
are taken into consideration.
Secondary boiler minimum runtime
If the secondary boiler is started, it will run for at least the
length of time set here.
Minimum temperature of secondary boiler
When the secondary boiler reaches the specified
temperature, the loading pump is started and switches the
isolating valve.
Temperature difference between secondary boiler and
buffer tank
Temperature difference between secondary boiler and
upper temperature in layered tank to activate the loading
pump of the secondary boiler.
Oil valve shut delay
If the current boiler temperature of the secondary boiler
falls below the value that is set under
“Minimum
temperature of secondary boiler”
, the isolating
valve only switches once the set duration has elapsed.
