Honeywell V4043H 1056 2 Port Zone Valve Normally Closed 22mm

Product Information

Travis Perkins were selling BOSS brand genuine SYNCHRON motors in the past but their web page photo now shows what looks to me like a cloned motor. Starting with the controls set for Heating Only, hold the lever tight against the right side of the slot. Follow links through to various manufacturers sites, as each manufacturer will have its own terms and conditions for qualifying for longer warranties. Honeywell use Synchron motors and these are freely available but there are lots of cheap cloned motors out there.

If the powerhead was removed from the valve to make it easier to change the motor, it must now be re-attached to the valve.The auxiliary circuit (grey and orange wires) is commonly used to operate the boiler and/or the circulating pump. It sounds a bit counter-intuitive, but when a switch is closed it is completing the circuit and allowing current to pass; when the switch is opened it is opening a break in the circuit and stops current from passing. I;m assuming that you've got no hot water due to the overheat malfunction - in which case there's nothing to stop you hooking the valve open permanently if this resolves tha banging until we determine why the valve isn't opening.

On each product, under the specification tab, you will find more information on the guarantee or Warranty. With very old Honeywell motorised valves the powerhead could not be removed without draining the water first.

You can then lift the lever slightly and release the pressure so that the spring pushes the lever back, leaving it caught behind the hook at the top of the slot.

If the motor is receiving 240v (on the brown and blue) it should rotate the spindle about 15 degrees and operate the microswitch. The Honeywell motorised valve faults detailed above are likely to apply to most domestic Honeywell valves. These 22mm valves (3-port V4073A1039 and 2-port V4043H1056) are used in smaller and medium sized properties.With the new motor in place, the wires must be tucked in so that they fit within the metal cover without pinching. The powerhead can only fit one way round onto the valve body but if space is tight that might not be obvious.

If, for example, the heating valve is failing in this way, you will get heat round the radiators while the cylinder hot water is being heated too. There is always an open pathway from port AB to port A or from port AB to port B or from port AB to both ports A and B at the same time.Hooking the valve to being permanently open will not damage anything - it simply prevents a spring from pulling the valve back to the closed position.

In summer, of course, with no heating on, this fault on the hot water valve would show up very quickly because the heating valve would not be telling the boiler to fire. This motorised valve was also rusting through round the screw in the picture Honeywell powerhead (actuator) jams? If all the power to the central heating system is turned off, and the manual lever is still loose across the whole slot, the mechanism may be jammed.
