About this deal

It may be easier to have the valve set in the manually open position using the manual lever. (See Honeywell Motorised Valve Manual Lever, below.) A programmer and cylinder thermostat (stat) are used to control the times when the hot water is heated and to control the maximum temperature of the stored hot water. The blue wire is the Neutral, N. The green/yellow wire is the Earth wire, E. The white wire is connected to the wire from the room thermostat which calls for heating (radiators or underfloor). The grey wire is used to drive the valve to the Water Off position, in which only the heating port A is open; it closes port B. The orange wire provides a Switched Live (Switched Line) feed to run the boiler and pump. Move the valve’s manual lever to the manually open position. (Push it towards the MAN OPEN end of the slot and lift while releasing it, so it settles into the hook at the top of the slot.) In smaller properties there is usually one programmer which has two channels. One programmer channel controls the heating (radiators or underfloor) and the other programmer channel controls hot water. Where additional zone valves are used there will usually be another programmer or timer. Honeywell motorised valve construction

A normally-closed valve is closed when no power is being applied to it and needs electrical power to drive it open. Seized motorised valve spindle in an old Satchwell Sunvic 2-port motorised valve. The water leakage has caused white oxides to form round the brass spindle, making it too stiff to turn Typically, a small or medium sized property will have either one 3-port valve (which splits the central heating water flow between cylinder and radiators) or two 2-port valves (one governing flow to the cylinder and one governing flow to the radiators).System boilers may also have a diverter valve or zone valve built into them and might not have any external zone valves. This can cause the valve spindle to seize. It often becomes stiff to turn at first and the valve may give intermittent problems. Eventually, the spindle may become so stiff that the valve motor cannot turn it at all.

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 power head cover can then be refitted and secured with the single screw. Make sure it sits squarely on the powerhead, with no wires pushing out from the sides. Honeywell V4043H1056 22mm 2-port zone valves have five wires: green/yellow is Earth, blue is Neutral, brown is Live (or Line) to the motor, grey and orange are connected to the end switch and form part of a separate circuit. The raised bump or pip on the metal cover of the powerhead or actuator of a Honeywell motorised valve Removing a Honeywell motorised valve powerhead A programmer and room thermostat (stat) are used to control heating times and room air temperatures. The programmer and room stat may be combined into a single programmable room stat. am i right in thinking this motorised valve will let me replace the motor without having to get wet or drain the system?They took 25 minutes total. I am happy with that because snow is forecast this weekend but I just want to know if this fee is considered OK as I may need to use them again. Comments please. One of the wires from the powerhead must be connected (crimped) to one of the new motor wires. The other free wire from the powerhead must be connected to the other wire of the new motor. It doesn’t matter which of the two motor wires is connected to which of the two free powerhead wires as they are polarity free. Crimps are metal tubes within plastic insulation, which are flattened using pliers to trap two wires, joining them electrically. These crimps can sometimes be re-opened by using pliers to squeeze together the edges of the flattened tube. This can be done with the plastic in place. If successful it frees the two wires. The plastic insulation may break, in which case the crimp is discarded.
