I have a problem with a daikin VRV 3 two pipe system which i'm struggling with. On arrival i found the controllers in a U3 fault which i suspect was caused by the onsite general maintinance engineer trying to get it to run and not completeing test run.
So test run was completed by myself. Test was completed with H3P led solid on condenser and no faults on indoor unit controllers. When trying to run the system normally just by the controllers the system will only run the condenser fan and not and bring the compressor on. No fault codes are displayed on indoor controllers
While in test run the system seemed to perform ok possibly slightly short of refrigerant but not enough to cause a problem.
The System is connected to a BMS Computer, not one that i'm familiar with only used the I-touch beforehand.
Any suggestions would be much appreicated as i'm back there on Monday 13th Jan
