WOODMASTER OUTDOOR FURNACES • OWNER'S MANUAL
Electronic Temperature Control (ETC)
Guide
Function:
• The ETC monitors and controls the WoodMaster water temperature
by controlling the draft and draft fan.
• During normal operation (adequate wood supply) the controller will
turn off the draft and draft fan when the water reaches 170°F (Set)
and will turn on the draft and draft fan when the water falls 10°F
(Hy).
• During shut down (low wood supply) or when the water falls to
120°F (ALL) the controller will shut off the draft and draft fan. At this
time, the WoodMaster will need to be filled with wood and the ETC
will need to be reset (see Startup).
Energy Start Shut-Down:
• This function shuts down the WoodMaster draft and draft fan when
not in use and back-up system is operating (example: if gone for the
weekend, wood firing furnace runs out of wood and back-up system
takes over). To restart the WoodMaster, simply push the Set Button.
Start Up / Reset:
• The first time the WoodMaster is powered up or when it has
shutdown, the controller display will flash "LA (Low Alarm) two
times and then display the water temperature for two seconds and
then start over. This is normal and indicates the system has shut
down because the water is at or below 120°F.
• To start up (or reset) your WoodMaster, press the set button one
time. The display will indicate "rSt" (reset) and after 1 to 2 seconds,
the draft will open and the draft fan will turn on. The display will
continue to flash "LA" and the water temperature will be displayed
until the water temperature reaches 140° (ALL + 20). After water
temperature reaches 140°F, only the water temperature will be
displayed until the water temperature falls to 120°F.
• Note: The fan switch must be in the on position.
• Note: Fan switch can be shut off when loading or for servicing.
