CM927 Problem

[Mfuller]

Hi Guys,

Got a CM927 that I installed a few years ago. It's been running fine, until the other day. I noticed a red flashing LED on the relay box.

I've looked it up and it seems to indicate loss of connection with the room thermostat. I've placed the thermostat next to the relay, but it's not reconnecting. I've changed the batteries in the thermostat and power cycled the relay. No luck.

I've looked at the installer manual, but I can't seem to find a way to force a re-sync. Is there a pairing procedure for these units?

Any help appreciated.

Typical.. search for about 30 minutes. No luck. Second I post this, I find the procedure on YouTube of all places!

Re-sync worked. Happy chappy.
