BOILER
This menu can be used to integrate an additional peak load boiler
using a third accumulator temperature sensor. With a double hea-
ting system, both boilers store energy in the accumulator. If the base
load boiler cannot charge the accumulator by itself, the peak load
boiler switches on for support.
This menu allows you to configure which heating system will be the
base load boiler and the which will be the peak load boiler in a
double heating system. A changeover is required after a certain
amount of operating hours so that both boilers will have approxi-
mately the same number of operating hours over several years.
✎
See “Procedure” in this section.
This is an optional submenu and only available with double heating
systems.
