Page 17: Displaying / Modifying Control Parameters
If parameter A 09 (frost protection limit) is set lower than the factory setting, frost protection is no longer ensured. This can lead to heating system damage. The settings in column 1 apply to control accessories ART, AWT. The settings in column 2 apply to Wolf control systems with programming module BM. Parameters Unit Factory set. -
Page 18: Limiting The Maximum Output
Limiting the maximum output The output setting can be modified with Wolf control accessories with eBUS capability via parameter HG 04. The heating output will be determined by the modulation current of the the gas valve. By reducing the modulation current in accordance with the table, the maximum output will be matched at 80/60 °C to natural gas H and LPG. -
Page 19: Selecting The Pump Stage
Selecting the pump stage The boiler is equipped with a three-stage pump that is set to stage 2 in the delivered condition. Stage 1 The minimum circulation volume is ensured by a connection Stage 2 line between the flow and return. An automatic overflow valve and a manually adjustable bypass valve are integrated into the Stage 3 connection line. -
