Timer There are 4 heater start-up cycles possible 7 days per week. The timer is separated into to three categories.
The user can select "Mon-Fri", set each specific timer (T1 – T4) for a typical work week all at once. A
weekend "Sat-Sun" can be scheduled in the same manner or a full week by using the "Mon-Sun" selection.
The "custom" link allows the user to set a specific timer (T1 – T4) for each individual day.
When selecting a specific timer a sub-menu will appear (Edit, Skip, and Off). To change the timer cycle,
select "edit". Changes are saved immediately. The "skip" feature allows a timer cycle to be skipped one
time within a 7 day period. Timer will reactivate after this one-time skip cycle.
Note: To turn a specific timer off permanently select "off".
LVD LVD "Low Voltage Disconnect" allows the user to adjust the battery voltage level at which the Webasto
SmarTemp Control fx 2.0 will shut the heater off. A warning (LED and message) will appear after 8 minutes
of low voltage. The warning will remain on for 2 minutes before the heater is shut off.
If battery voltage is equal to or less than the threshold selected +0.1v, the heater will not start. i.e. if an
11.5v threshold is selected the heater cannot be started until B+ has reached 11.7v.
12 volt - Range between 11v – 12.5v | 24 volt - Range between 21v – 25.5v
Default Default allows the user to perform a reset to all default values.
Note: A power loss will not reset user programmed values.
