I'm replacing an old Switchmaster 400 with a Tempus 7, thought it looked easy but a couple of nagging worries.
Apologies for non industry standard terms!
On my Switchmaster 400 it says terminal 2 should have no wires attached yet it has 3, two blue and one black. One of the blue wires is attached to the neutral terminal. Are these just like this to save on boxing them off? And there's nothing in terminal 4 (CH/Off) but there's not one when i wired up my Drayton Digistat 1 so presume it doesn't need one. Terminal N has three blue wires, terminal L has 1 red wire, Terminal 1(C/H on) has one red wire, Terminal 2 see above, Terminal 3(H/W on) has one red and a yellow wire, Terminal 4(C/H off) has nothing and there are two more yellow wires boxed off. Earth is pretty self explanatory (3 of them).
So should i just wire them up on the Tempus 7 to the correct pins as per instructions just boxing off the wires in terminal 2 and the two yellow wires or should i just phone someone who knows what they're doing up. What's the worst i could do? Blow the 3 amp fuse? Or maybe not!
