MC424 install WI-FI Switch

[psmedley]

I am new to the forum.
I have the exact same wifi receiver and I would like to connect it to a Nice Robus 400.
I just don't know what goes where.
Please help

Hi Peter,

I hope you are well. You will need to take your power from the right side of stop and the left hand side of PP. The right hand side of stop is negative (-) and the left hand side of P.P is positive (+). You will then need to wire into P.P instead of COM and SBS. The polarity of this does not matter, simply wire from the smart switch into the P.P terminal, it is fine to have this and your power wired into the same terminal.

Thanks for  this - what voltage should I expect to receive from the right side of stop and the left hand side of PP?  24VDC?
