Hi Chaps
Im hoping someone out there can give me some much needed advice.
I have a system which comprises of 6 void indoor units on 1 outdoor unit, its a 3 pipe system with individual bs units.
In cooling mode all units work fine, but in heating 1 unit is not heating, its the nearest unit to the condenser, im convinced its not a gas charge issue.
At the bs unit the discharge pipe is hot but a bit cooler out of the bs unit to fan coil.
I spoke to daikin and carried out various checks and the strange thing was that the thermistor temp was 41 degrees, but def no heating from fan coil.
I think that there is a blockage in the bs box limiting refrigerant to fan coil, the problem i have is that being R407c Daikin do not do a replacement bs box but sell each solenoid component individually.
i could order these up and strip the unit down and fit, but now i have come away from the job (its a 3 hour journey) im thinking could it be as simple as the indoor unit thermistor faulty.
that would be ideal as i would not have to de gas system.
Please help;)
