Viessmann Vitodens 100-W PCB 7506590 Type 2 (3 Relay) – Refurbished
SKU: PCB-2945-A-BC-V1
The PCB in a Viessmann Vitodens 100-W boiler manages ignition, heating cycles, and safety controls. A failing board can cause lockouts, erratic temperature control, or complete loss of heating and hot water. The Viessmann Vitodens 100-W PCB 7506590 (Type 2, 3 Relay) is the direct replacement for the Type 2 three-relay variant, restoring precise control across the compatible Vitodens 100-W range.
This is a professionally refurbished unit, tested to ensure reliability, and supplied with a full 12-month warranty. Two service options are available:
- Direct Sale — refurbished board shipped to you, ready to install.
- Advanced Replacement — board shipped immediately; return your old board within an agreed window.
