Greetings to all,
I am hoping for some advice regarding a system; PURY-P400YGM, the 5 fan coils are PEFY-P125VMM-E(DUCTED). I have visited the site but could only access the outdoor unit, the problem is that on one local controller PAR-27 the mode button flashes irrespective of what mode is selected, Mitsi technical suggested that this could be caused by an incorrect port address, as the system is a couple of years old what other faults could cause the same symptoms? I shall return to site soon when I can gain access to the entire system, I will not have the benefit of Mitsitechnical however because this will be out of office hours. I shall also fit remote return air sensors on all the systems on this site as the remote controller sensors that are currently being used are not ideally located, does a setting exist like the daikin factory setting where the system can use both unit and controller sensors? Finally I have a spare PAR-27 controller and was considering connecting it to the outdoor unit to test each fan coil, as I have never attempted to register/unregister a controller like this, how complicated is it?
Lets hope that this weather continues!
Thanks in Advance
