Possible only with Truma Combi eco plus
and Truma Combi comfort plus furnaces
with electric heating elements.
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 120VAC power supply:
The furnace automatically switches to gas
mode. When the 120VAC 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
mode again, the cause of the malfunction
must be remedied and the furnace has to
be started again by going to the menu item
“Malfunction” and pressing the rotary push
button. See “Malfunction” on page 11.
Special features in electricity mode
• When the 120VAC power supply is inter-
rupted and the 12 VDC supply is on, an error
code is displayed on the control panel.
• 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.
