## Questions & Answers

**Q: Does anyone know the diameter of the wire? Need to purchase furrules?**
A: Not sure what you mean by ferrules but from memory, the wires are about 2.5mm diameter.

**Q: Is there any photos of bottom of this product**
A: Unfortunately unable to supply any photos.

**Q: Danfoss 5933  how does the manual lever work**
A: The manual lever ensures that the hot water flows through the radiators, it can only be moved towards you when the radiators are selected ie. red light ON and the thermostat is set high enough so that flow can happen. Do not try to force the manual lever, it moves easily when what I have said earlier is correct.
I use this facility sometimes when the main valve for automatic selection gets stuck and I need water to flow through the radiators.

**Q: Hi i need to replace this item , the one i have has hpa5 will this work ? thanks**
