Upinor (Wirsbo) control module compatibility

[tomswell]

I have multiple zone Wirsbo controller with two wires only going to each zone thermostat.

A Nest Power Connector for an individual zone hasn't enabled usage.

the Wirsbo control module input terminals: ( best that I can determine)

#2  Rh

#3 W

#4 C

out of frustration I tried reversing RH & W to no avail.

Has anyone verified compatibility ?

Hi tomswell, 
 

Thanks for posting here in Community. Can you help me with the photo of your previous thermostat and your Nest thermostat wiring? Furthermore, you can check this article to see your system’s compatibility to our Nest thermostats. 

I look forward to hearing from you. 

Thanks,

Zoe
