Hi
A customer has daikin unit , outdoor model rzq100kv4a , the controller is brc1e61.
The problem is even when its hot outside and inside the unit doesn't ramp up and run on full capacity. The symptoms are suction pressure 160psi ,(r410a 14 degrees) and outdoor amps 8amps as it should be around the 12 to 13amps.
The back story
- A subcontractor attended site and used a daikin diagnostic tool that said all the outdoor sensors and transducers are okay. He spoke to daikin whom could not give a explanation for fault except to replace the outdoor and indoor boards. These boards were replaced yet we still have the same problem.
Also when the unit is put onto test mode via the controller does this bypass the sensors and run the unit at full speed because when I put onto test I get the same result
Please help,
