You can set your stats anyway you would like. My board will do what ever the stats tell it too.

Give us a call when you get a chance

Yes you can use the nest connector

For zone 2 and 3 you need the "C" wire for your nest stat to work. You will need to run a new wire or just go with a single stage none WIFI Stat

"Y" = Cool
"W" = Heat
"R" = Power

Give us a call when you get a chance. 1800-446-03110

Are you using the "ONE ZONE" terminal on the Zone 1 T-Stat lower left hand side of the board?

PRO 1 Thermostats
T601-2 – None Programmable
T725 - Programmable

We no longer make the ST Boards do to the stats that work with the ST Boards are hard to find you may need to update your board to a NCM 300

Here is where you can get the stats or the NCM 300 from: www.supplyhouse.com

You are going to need the Bmplus 5000. That will give you 5 zones so you will have a spare zone. You can order the Bmplus 5000 at www.supplyhouse.com

Give me a call when you get a chance and I will walk you thru this setup
