Mid position valve wiring diagram. 5 watts replaceable actuators motors 100 tight shut off. This causes the valve motor to move to the mid position and water from the boiler flows to both the hot water cylinder and the radiators. Part 4 in the heating wiring series covers how the 3 port mid position valve works internally allowing 3 separate positions from only 2 mains inputs. The honeywell v4073a three port mid position spring return valve is a masterpiece of clever engineering.

All models feature snap on actuators and have industry standard wiring and dimensions. V4073a mid position y plan valve operation pipework schematic the valve must always be connected so that the flow of water goes into port ab and flows out through either ports a or b or both a and b. Installation instructions mid position valve val322mp val322mp is a 3 port spring return mid position valve with 22mm compression fittings and an auxiliary switch. It manages to move to one of three positions using only a cheap non reversible ac motor a spring a couple of micro switches a resistor and a diode and act as a relay for the boiler into the bargain.

5 wire spst switch 230v a c. The valve must be sited so that the head is not below the flow through the pipe. Work must be completed by qualified electricians or heating engineers. As with hot water only the orange valve wire is connected to power via the wiring centre terminal 8 but orange is still not connected to anything inside the valve.

You can find an increasing number of experience as well as understanding how the life is undergone. The drayton mid position valves are available in 22mm and 28mm. This is for use on fully pumped systems which when correctly wired with an appropriate room thermostat cylinder thermostat and programmer will control the water flow. H w heating cylinder boiler flow b a ab mechanical operation.

Installation instructions v4073a motorised mid position valve application the v4073a valve has been designed to control the flow of water in a small bore domestic central heating system where both radiator and hot water cylinder circulation are pumped.
