ELECTRICAL CONTROLS:
The AHS Furnace is designed to maintain a constant Furnace Temperature (Higher than
180
0
) controlled by the Operational Temperature Aquastat (OP) and the High Limit
Aquastat (Hi) located at the top of each furnace. The OP Aquastat is in series with the Hi
Limit Aquastat. The Hi Limit Aquastat is used only for safety. If by some means the
operational aquastat allows the burner to operate over it’s set point, the Hi limit Aquastat
will shut the burner down some (most Hi Limits have a manual reset).
ELECTRICAL CONNECTIONS:
Heat is provided by the primary control on the burner. We have a very simple electrical
hook up. When installing your burner to the AHS Waste Oil Furnace, just locate the cable
with 2-conductor thermostat wire (red, white, black) coming from the junction box on the
side of the furnace to your burner. Then find the thermostat “T” terminal screws on the
primary control and attach 1 wire to 1 “T” screw and the other wire to the other “T” screw.
See Illustration on the next page. The
red
wire is for oil pump power, the
white
wire is
neutral and the
black
wire is power.
