Older Weathermatic controller expansion module?

[justgeorge]

Got a customer with an older Weathermatic controller (pre-Smartline). It has an empty slot to take it from 9 zones to 12 zones, looks like a pretty simple plug in module. Not made anymore though. Anyone know where to get one (or has an old controller sitting around to swipe it from)?

Thanks

Can somebody help out here? Give the name of the controller justgeorge.

I think it's an S9. However, I was able to wire two zones together (one only had 1 rotor, 1 had 2 rotors) to free up a zone. Should have thought of that first, duh. The zone with one rotor on it was like that because the customer had expanded his garage which took out the other rotors on that zone.
