That's going to depend on whether Bill has put a link between the two red wires on the tag strip.

I also think it's important to check for faults in the heater chain before powering up. Remember that some of the valves light up even though the magic eye heater is disconnected from the chain.

There's also the problem of the low resistance between HT positive and the UL41 pin 4. It's possible this is down to Bill's meter charging up the smoothing caps.
