If you are experiencing difficulty to locate & resolve a difficult problem with City Multi VRF equipment then Tim is the engineer you need.
Because Tim has specialised in City Multi VRF since 1992 & was employed by Mitsubishi Electric for 7 years as Senior Technical Service Engineer he can draw on years & years of trouble shooting & problem solving experiance with City Multi systems.
Tim also has the benifit of specialist factory training with Senior Mitsubishi Electric factory engineers in the UK & Japan.
It is therefore a very rare day that Tim finds a fault which he has never seen before.
No mater what the problem is Tim can deploy a number of trouble shooting techniques to quickly & efficiently locate & resolve any problem.
The older the system becomes the more small faults can stack up un noticed & will contribute to poor system performance making trouble shooting challenging. A number of minor faults can be hiden behind a major fault & can be contributing to the major problem & will inevitably result in poor energy efficiency.
Poor system performance may go unnoticed by the end user for many months however it has an ongoing & negative impact on energy efficiency until the day that the system finally stops on a major fault.
Typical trouble shooting & problem solving issues may include,
1/ M-net communication problems.
2/ System short of refrigerant.
3/ Intermittent electronic faults.
4/ Inverter circuit faults.
5/ Poor room temperature control.
6/ Poor LEV valve & solenoid valve operation.
7/ Pressure sensor faults.
