Truma wants you to have the best experience using the Truma Combi CP Plus so we’ve come up with some tips so you don’t feel overwhelmed.
The first step to getting the best out of your Truma Combi is to understand the CP Plus. To wake up the CP Plus, press the round toggle switch and you will see it begin to initialize. There are icons at the top of the screen that will allow you to set room temperature, water temperature, fan speed and whether you would like to use gas, electric or a combination of both.
Setting your Combi’s water temperature set point
To set the water temperature set point, turn the toggle switch until the water/thermometer icon begins to blink and press to select the image. You will then have the opportunity to set your water temperature to different set points.
OFF
ECO mode which is 104° F or 40° C
HOT mode which is 140° F or 60° C
Boost mode which is the set point you want if you are going to shower. Boost mode increases the water set point to 144° F or 62° C and turns off the furnace fan.
Setting your Combi’s water temperature set point
