Function test of the cooling and heating modes Remove the protective caps from the valves. Start the commissioning procedure by briefly opening the shut-off valves on the outdoor unit until the pressure gauge indicates a pressure of approx. 2 bar. Check all connections for leaks with leak detection spray and suitable leak detectors.

Procedure DC fan motor of the indoor unit (control chip is installed in the motor): Switch on the voltage to the unit. In standby mode, measure the unit between terminals 1-3 and 4-3 of the connector plug. Check the measured values against those listed in the table below. If these differ, there is a problem with the control board and it must be replaced.
