MH-083 Ecomaster Comfort user manual
1.14.2. Normal mode.
In normal mode, the pre-heater either operates automatically as a support for the heating system or else
manually during a time determined by the user.
If you press key (8) for a short time you enter the pre-heater screen. In this screen, the flame symbol in-
dicates if it is operating (flame filled in), whether in normal or programmed mode, or if it is switched off (hollow
flame). If it is working in normal mode, a counter will appear with the operating time remaining.

Using the driver’s keys (1) and (2) you select the operating mode of the pre-heater (AUTO, ON or
OFF). For the ON option, you can select a time for the heater to come on using passenger keys (16) and
(17).
The pre-heater comes on if it is necessary and the outside temperature is below 15º or the outside
sensor is broken.
The pre-heater comes on for the selected time, (unless you are in diagnostic mode) and then returns to
AUTO mode. If you select the MAX time, the pre-heater continues to operate for 2 hours after the mo-
tor of the vehicle has stopped.
Switches off the pre-heater whether in AUTO or ON mode. When OFF is chosen, the preheater will
only work if there is a request coming from a programmed mode. Any other petition to activate the pre-
heater will not be considered by the system, even those that the system makes automatically as a su-
port for heating.
Once the ON mode is selected, after a few seconds the screen will show the pre-heater operating symbol.
