When the furnace is switched on (room tem-
perature, hot water level active), the energy
mode selected in the previous heating pro-
cess is shown in the status line. The factory
setting is gas.
Special features in mixed mode
Interruption in the 120VAC power supply:
The furnace automatically switches to gas
mode. When the 120VAC power supply is
restored, the furnace automatically switches
back to mixed mode.
Fault in combustion process (e.g. fuel
shortage):
The furnace automatically switches to elec-
tric mode. If the furnace is to run in mixed

button. See “Malfunction” on page 11.
Special features in electricity mode

rupted and the 12 VDC supply is on, an error

When the 120 VAC power supply is recon-
nected, the furnace will restart automatically
with the previous settings without any user
interaction. The error code on the control
panel will disappear.
