Re: Dayton ProgrammableThermostat 1UHG4. I'm using this stat with a toe space heater that has a simple 1 thru 10 stat built in that is not very accessible. According to the heater manufacturer all I have to do is connect the black and white wires from the 1UHG4 stat to their wires eliminating their stat. My question is What terminals on the 1UHG4 stat (L,1,N) get the black and white wires from the heater? I suspect white goes to N terminal and the black wire goes to either L or 1 terminal but am not sure.

Hi,
Actually it is not quite that simple....

The N wire is the neutral or common and needs to be hooked to the white incoming power on the heater. You will probably have to run a new wire to this from the wire wire that feeds power into the heater...
The L in the line power that runs the t-stat and also provides power back to the heater....that needs to be hooked to the incoming "hot" to the heater. This probably gets hooked to the black wire that was hooked to the old t-stat...
The 1 is the switched power going back to the heater to provide the power to turn on the heater....this probably get hooked to the white wire that was on the old t-stat.

I hope you can follow all of this...I tried to make it as clear and simple as possible...

Nothing ever as easy as the manufacturers try to make you think that it is... :-)
