Siemens rev100 thermostat help

[Raas]

Hi All,

I'm having a bit of trouble getting to grips with this product.

I bought it to replace a very old honeywell roomstat. Upon removing the honeywell, there were 4 wires, 2 red 2 black feeding the unit in positions labelled 1,2,3,4. How these relate to L & L2, T1 & T2 I don't know!

I took some meter readings but this didnt tell me much. Ive since had it wired up but when the central heating control has hot water and ch on, the rev100 seems to get confused and alternate between 'remote' and 'burner on' modes.

I am yet to get any heat into the radiators. But there is plenty of hot water and I can here pump like noises.

If anyone has any experience with this unit, I would really appreciate some help.

Many Thanks,

Raas

Surely it came with instructions and a circuit diagram.

It did.

Instructions were very pretty but unhelpful and this is the circuit diagram included.

I am unsure how the rev100 unit works with the central heating control unit (in this case a honeywell ST6300A).

Here are the connection details for the REV100
