My system has no CH but HW is ok. Have shorted red and yellow at programmable battery operated stat still no power to orange on wiring centre. Have butchered a synchron motor from a Drayton onto the Honeywell . If I press the microswitch in the valve then the motor does energise and pushes onto other switch and boiler calls for heat.
Have moved the valve to manual and locked into position and now have heating.
Is this a 3way valve or programmer issue?
The valve is v4703 A1039 new head is part number 40003916-003 according to the label on the inside.
Thanks for help
PS spindle seems to rotate ok by finger pressure
