Q: The hot water will not switch off at the controls and continues running until the main power supply is turned off. How can you determine if its the valve or the programmer?

A: Turn the cylinder thermostat right down, if it switches off when you do, it is the programmer at fault.
Q: Is it the 5 or 6 wire version?

A: It is 6 wire. When replacing a 5 wire actuator you simply isolate the extra white wire.
Q: 1. Is this the closed or open variety? 2. Does it include any instructions 3. Whats the warranty period?

A: The Honeywell 40003916-001 replacement powerhead is normally closed power to open. Yes it does include instructions. The warranty is 1 year from purchase.

Exceptionally fast delivery - item ordered was exactly as requested.
bought this actuator for 3 way water valve for underfloor heating system and when it was delivered 2 days after ordering it was just a case of popping in back on the water valve and wiring it up. I did have a bit of a problem with the securing clips as they broke, but slipped the ones from the old valve and they fitted fine. System back working perfectly again, thanks for the prompt service. The part was replacing one which had been on the system for 20 years and I did not considered looking for cheaper or different parts best go to replace the original. Ged Gourlay, Dundee
Quick & efficient. Good service.
