We have a vrf Mitsubishi that on heating the compressor is making a short cycle. It starts for one minute and stops for two minutes . we are suspecting that is low on refrigerant but we cannot overide the program so thu unit runs full speed to check the pressures. the indoor units are with a wireless remote and there in no falut code on them . actually the unit has no fault it is only not sufficient on heating . we added some refrigerant and the pipe temperature was improving so that is why we keep assuming that it is low on refrigerant .
Could you be so kind to tell us if there is a test run button to check the performance .? and how ?
