Replacing a CH/HW Controller 3000 Programmer
Hi,
I'd like to replace my old Central Heating/Hot Water programmer and can't work out the connections. The programmer I have is: Controller 3000 made by "Smiths Industries Environmental Controls" Type 67-040-15 240v 10W 5A switch rating Wall Plate Asssembly: 67-070-68 Pin layout: L N E 1 2 3 4 5 6 7 8 9 10 LNE is obvious Pins 2 3 4 all control the 3 port valve A wall thermo is conected between 8 and 9 A HW cylinder thermo is connected between 8 and 10 Pin 7 is live (240v) I'd be really grateful if someone could help me out with the pin allocations or point me in the direction of a spec. Cheers, Warren |
