For quick reference the Truma C69 DZ owners manual is located here. 

For settings, temperature is easy - set to your preference.    The other setting that is interesting is that for battery voltage protection.   For both flooded lead acid (the factory Canadian Energy cells, or equivalent,) and for lithium iron phosphate, the recommended initial setting is HIGH.

If the fridge will not start, it can be changed to medium.   Remember we only want to see the lead acid cells get down to 12.2 or so volts, which is 50% charge.   See the article below for more details:



Above is a tech sheet for the C69 - current required at 12v it 6.3 amps - this information will help with power consumption calculations including those for solar panels or battery capacity so one can have a starting point for runtime.    The factory batteries without any assistance is roughly 100 amp hours; but the fridge does not run full time.   At ~50% duty cycle, you end up around 30 hours running the fridge only.   Duty cycle depends strongly on fridge loading and outside temperature.   Running the unit with as much fresh air circulation as possible helps.


NOTE: The cigarette lighter style plug for the 12v system that powers the fridges can come loose in rough conditions.   If you are experience low voltage/shut down of the fridge, but the system voltage is above 12.3 volts and the other DC systems are performing well - check this connection!   It is behind the fridge between it and the 7 pin box/battery box.


If you have technical concerns or failures  with the fridge, the warranty is administered by Truma.
