– Standby operation with anti freeze function
In this operating mode the water in the cylinder is warmed up so far in standby operation that the
water in the cylinder cannot freeze.
Note: the keep warm function works only, if the external safety chain is closed. Therefore this func-
tion may not be used for outdoor operation.

upcoming Idle submenu set the parameters for standby operation with anti freeze function.
Settings:
• “Idle Mode”: “A.Freeze”
• “Heat Power”: heating power for anti freeze function (Factory setting: 50 W, Setting range:
10...200 W)
