dHC 2000 normal oPeraTion - on/oFF mode, wiTH THermosTaT or wall swiTCH:
Thermostat contacts are closed
(it is calling for heat).
If the stove is OFF then the unit will start the start-up sequence.
After the 15 minutes, the operator can now change the heat output, low feed trim, and whether the
convection blower is ON or OFF (depending on the model).
The convection blower can be turned OFF by depressing the convection blower control button. When the
air jacket reaches 160°F (71°C) the convection blower will come on high, cooling the unit. For the best
efficiency and to prevent cycling, the convection blower should be left on at all times.
When operating on LOW HEAT LEVEL, the feed rate can be adjusted, using the auger trim, for different
quality fuels.
If the unit was in the LOW mode when the thermostat closes then the controls will change to the Manual
mode.
Please note: When the heat output is changed, the combustion blower and convection blower speed
change as well.
