What it is
The Siemens LMU64 is an electronic boiler control unit listed by Hamworthy for its appliances and referenced F40W NG. It forms part of the boiler's control circuit, handling the electronic control function within the appliance rather than sitting in the gas or water path. This listing is for the control unit only.
Before you order
- Confirm the reference on the existing control matches LMU64 and the F40W NG variant before ordering.
- Check the boiler data plate and confirm the appliance is on natural gas, as indicated by the NG reference in the part name.
- Note or photograph the wiring and plug positions on the existing control before removal so the replacement can be connected in the same order.
