My old proscon thermostat has 4 connectors.two separate cables feed into it: 3 core plus earth, 2 core plus earth
3 core- yellow, blue, red, earth
2 core- red, black, earth
3core- yellow to terminal 1, blue to terminal 3, red to terminal 4
2 core- black to terminal 3, red to terminal 2.
Any idea how this can be rewired into a new thermostat?
