Hi guys, hoping somebody can help me out. During commissioning a Daikin vrvIII multi with 3 outdoors a valve was left closed on one unit causing an E3 fault. After opening valve and resetting system, tried to start again and test run only lasts a few minutes and trips out on E3. Same problem several times. Am I not resetting properly, killing indoor power, then outdoors, power back all indoors then condensers while holding reset on master outdoor for 30 seconds. System initialises fine and I can start a test run but same fault occurs after a few minutes but no issues with my gas pressures in the short few minutes they run. Thanks
