Question about Electrical Supplies
What do ''comm'', ''satisfied'' and ''demand'' relate to on the wirin diagram. i am not using it in a conventional heating setup but a plant growroonm to maintan constant temp control of stand alone heater.
i know one must relate to live ,earth etc but which ones?
Comm should be the common terminal/wire
Satisfied means that the unit is no longer calling for heat because the thermostats setting has been "satisfied" and has shut the unit off until the room is cooler and it is then "damanding" operation. This should bring the unit on. (when the thermostat is in "demand")
