the same conduit as the load wires or supply voltage for the unit.
3.
Controller must have its own power source, i.e., no outlets or other loads
attached to the same supply source as the controller. Supply wire (hot) must be
run separately from load wire. Do not jump H terminal to load side. Controller
shall not be placed in any other enclosure other than its’ own or warranty will be
void. Consult factory for outdoor applications.
4.
The controller is to be installed where temperatures do not exceed 120°F or
below 32°F. For trouble free operation it should not be exposed to vibration,
dust, corrosive sprays or condensing atmospheric conditions.
5.
Control relays are SPDT dry contacts (unpowered) with LED indication when
relay is energized (when common and normally open close).
