Julitha R.asked

I have moved into a rental property which has this unit installed. It has a 'Heat' switch, but still seems to just pour out cold air. Am I stupid? Does this unit heat as well as cool??

2 answers

It should. If it doesn't then it's broken. They do work particularly poorly though and require frequent (several times a year ) services, in which they will have to either take the entire unit apart, or clean it with high pressure water. High pressure air doesn't work on these units from my experience.

But all that aside, even when not working well, they usually can produce some warm air.

I recently purchased and had installed a g series 5.1 kw and lately on the temperature screen on the ac unit, it's been displaying P5.
What does this mean?
Also, when we first operated it, it cooled very quick but now in the past week it hasn't felt upper cold like it did 6 weeks ago.
Can you help?

Hi! As you have said it’s a new purchase I would suggest you call Rinnai (1300 555 545) as the unit comes with warranty, otherwise maybe check your books which came with the machine? Sorry!
Mines still perfect.
Good luck!

Thanks Mimmo 105 for the question. With your model of airconditioning unit P5 indicates an overheating issue with the discharge pipe and the unit is shutting down as a protection. We would recommend booking a service call to diagnose the issue. our 1st care department can be reached on 1300 555 545.


As usual Rinnai is trying to play down the fact that their Air cons are nothing but cheap Chinese parts that break and over heat under the most normal of conditions AVOID RINNAI AIR CONS AT ALL COSTS CHEAP CHINESE PARTS!
