Hi,

I just bought a Noma thermostat to replace my older one (Robertshaw). When I disconnected the old one I had 5 wires an extra blue one? On the Noma I have no place for it? What do I do with it?

Thanks for the help

Joey

I have no idea with the information you have given.

Model/number of old thermostat.
Model/number of brand of new thermostat.
