Question on controlling light switch with specific condition?

(Alex K ) #1

Looking for help on how to configure specific situation.

I have a problem with my boiler that I’m troubleshooting but its a slow process and taking a long time. Meanwhile boiler blows out at random times and even though thermstats are working boiler is not which causes temp to drop. So to help with the situation I replaced my emergency switch with zwave one. now at least I don’t have to run to the lower floor to turn it off and on.

Here is what I want to do. I have 3 nests thermostats. I want to set up a condition where heating is on and temp keeps dropping below what it set to. If that condition happens I want to turn off the zwave switch, wait 10 seconds and turn it back on. How can I accomplish this? I can’t figure it out

thanks

Alex
