Swapping the heat exchanger for the summer box
The summer box is not capable of transferring heat or moisture. Instead, this module can be used to
replace the heat exchanger for summer ventilation while maintaining a supply air and extract air
mode!
In doing so, proceed as follows:
1. Perform work steps 1 to 6 as described in 5.5.1.
2. Insert the summer box module and perform work steps 9 to 10 as described in 5.5.1.
Display of working conditions on the control board
The control board is equipped with three LEDs for signalling working conditions.
The following working conditions are shown based on the LED display in Table 10:
LED
