INFORMATION
If 2 user interfaces are present, you can start a test run from both user interfaces.
▪ The user interface used to start the test run displays a status screen.
▪ The other user interface displays a "busy" screen. You cannot use the user
interface as long as the "busy" screen is shown.
If the installation of the unit has been done correctly, the unit will start up during
test operation in the selected operation mode. During the test mode, the correct
operation of the unit can be checked by monitoring leaving water temperature
(heating/cooling mode) and tank temperature (domestic hot water mode).
To monitor the temperature, go to [A.6] and select the information you want to
check.
During a heating test run, the unit will start up in hybrid operation. The setpoint of
the gas boiler during a heating test run is 40°C. Keep in mind the 5°C overshoot
that is possible during boiler operation, especially in combination with floor heating
loops.
12.4.4 To perform an actuator test run

For example, when you select Pump, a test run of the pump will start.
Purpose of the actuator test run is to confirm the operation of the different
actuators (e.g., when you select pump operation, a test run of the pump will start).
Prerequisite: Make sure that the leaving water temperature home page, room
temperature home page, and domestic hot water home page are turned OFF.
