Heater Reading at 27 blowing cool air

[EuroBoy]

SUBJECT SHOULD BE: Heater Reading at 28 blowing cold air

Hi All, :wave:

My Honda Euro 06 Standard is 3 weeks old and I've noticed that when using the heater I have to have it on "29" for warm air to start blowing out; 28 is cool air.

I was just curious to see when does warm air start for other Euro owners?

Is warm air at 29 normal, considering the gauge starts at 19 and goes through to 30 (or 31?).

I've tried this with Air Con Off and On, Dual On and Off and Recycle Air off.

I'm taking it to the dealership this week for the 1000km service, just like to know if this is something worth mentioning or if this is normal.

Cheers,

EuroBoy...

No it's not.It depends on outside temp.but mine puts out warm air from 23.Get dealer to check it out.should be easy to fix.:)

[LXRY]

Yes i agree with tony1234 if your worried about it or anything else get mention it to your dealer, thats what they are their for.....

[EuroBoy]

yeah, i'll mention it with the dealer this week.

tony1234: how does it depends on outside temp? :)

[dhdevil]

its called climet control, read your instruction booklet on how to use your heat/air-con.

[tony1234]

yeah, i'll mention it with the dealer this week.

tony1234: how does it depends on outside temp? :)
Its' because it is climate control.It adjusts the inside temp.relative to the outside temp.

[EuroBoy]

climate control doesnt adjust temp relative to outside - climate control maintains a constant inside temp based on your settings.

i'll mention it with the dealer this week, considering tony1234 gets warm air from 23 on wards. 27 on mine is still quite cool.

anyone else have warm air from 23 onwards?

[TypeG]

warm air should be out at 22-23 in winter 8am
i parked in the street and usually it is very cold.
i turn on 23-24 and put fan to the strongest, it should heat up after 5 mins to make me feel HOT
lol
i think u need to check with yr dealer

Yeah,that's what i meant.Depends on time of day,cold hot etc.23 good for AM winter then sometimes turn up during the day!

[EuroBoy]

yep - definatley looks like a problem. I'd be driving for over an hour and 27 is cool air even after toggling all the variable heating options.

[Adagio]

You might consider thatyour temp gauge may need calibrating. I seem to remember in the owners manual that thius is adjustable by 3 degrees C.

[Lowenhart]

Yep I get warm air from around 23, 27 should be fairly hot.

[kleung]

EuroBoy - have you checked the cabin temperature with a separate thermometer? If the cabin is at or above the temperature you set on the climate control, it would be normal for cool air to be coming from the vents. Sorry if I'm stating the obvious. :)

For the climate control to start pumping out warm air, two conditions have to be met - the cabin temp has to be below what you've set on the CC, and the engine has to have been running for long enough to warm up the coolant.

[BusterSonic12]

mine's started to blow out hot air around 24

havent actually used a thermometer to check the cabin temp - but i've toggled with all the other heating options.

in terms of coolant being warm - cool air stills blows at 27 after an hour of driving, even with the fans on max.

Adagio mentions that the temp can be calibrated by 3 degrees - i'll have to read the owners manual.

[TypeG]

just bring to the dealer if u cbf to read the manual

[kleung]

Actually, I'd expect the CC to be blowing cool air after an hour - after that long, the cabin should well and truly be up to temperature. Do you get warm air at all in that period? It's been pretty cold in Melbourne over the last week or so, so after an hour, the cabin should be significantly warmer than outside. If it is, then the CC is probably working as it should.

I think what Adagio is referring to is calibration of the outside temp display in the dash, and not so much the CC system.

But at the end of the day, if you're still worried that your CC isn't working as it should, your dealer will be able to test it for you and give you a definitive answer.

[ok2]

Yes, have used the "heater without AC on" quite a bit over winter (2006 Std) and got noticeably warm air from it when I set the temperature at 24 or warmer. However I did get cool air when temperature was set at 26 & 27 the other day. It's only done this once so assumed it was a glitch.

Thing I keep in mind is that this is controlled by a sophisticated and complicated computer based system so occasional glitches are not unexpected. However if you have a persistent problem, and you do seem to have one, get it looked at. Would suggest you

1) Make sure it is doing it when you take it in (you never know !)
2) Show the dealer the fault.

That way it you are certain they know the problem and won't give you the brush off.

[EuroBoy]

thanks for the info guys - i'm bringing it to the dealer this week for the 1k check and i'll ask them at what temp should hot air start blowing. i'll see what their answer is. ;)

[MiSloVic]

what i noticed is that the temp difference between ur set temperature and the outside temperature needs to be at least 10C before u will notice warm air from the aircon vents.
for ur case, the outside temperature could be at 18C, you need to set the temperature at 29C, in order to feel some warm air.. you may feel some heat at anything less than 28C, but it won't be as noticeable.

Hold down auto and dual when you start your car. The right climate control temperature will flash "1" and "xx" where xx is the cabin temperature. Your aircon should blow out warm air when slightly above xx and hot air when much higher.

[EuroBoy]

went to the dealer this week - they reset the ECU - it seems to have solved the problem, warm air gradually builds up from around 24 now. :)

[aaronng]

It depends on your cabin temperature too. Today, I had cold air blowing when I set the climate control to 29ºC.

[BiLL|z0r]

Mine blows cool air at 27-28 and that's what I have my cc set to most of the time. I'm on the Goldie so outside temp is warmer if that makes any diff although I did think it's very odd as well. Dad's Adventura CC is generally set low 20's.

[kleung]

OS temp has a bearing in that the CC needs to know what the temp of the incoming air is in order to be able to heat or cool it to achieve the desired cabin temp.

Something also to consider is that the 'perceived' temperature of the air coming out of the vents can be misleading. For example, on a hot day (say, 35C+ outside), air coming out of the vents at 25C would feel cool. But on a cold day, say, 10C, air coming out of the vents at the same temp would feel warm. This example over-simplifies things a bit, but the general gist of it is correct.

[aaronng]

Sunlight is also a factor. If you are in the sun, the air from the CC is colder compared to when being in the shade.

sorry to bring up an old thread. after i came back from my 10000k service. my car is blowing out HOT air even when i set the temp to 19 or Lo. changing the temperature only affects the fan speed not the temp of the air coming out from the vent. the outside temp is 22 (not sure if it's right for melb today) and seems to be stuck at 22 even when i'm in direct sunlight or underground carpark.

can someone help before i have to take it back to dealer. thanks.

[aaronng]

If it blows out hot air even at LO, then take it to the dealer.

Did you have the AC on or off? If you haven't already done so, try pressing 'Auto' and set the temp to 'Lo'. If the air coming out of the vents doesn't start cooling down, then it'll probably be a dealer visit.

I hope you're not planning to drive on Sunday or Monday (Max 38C both days) :)

Outside temp reading can take a while to update sometimes, especially when you've been parked in the sun for a while. But 22 was certainly not right for today, (max temp ~34C)

[tony1234]

That doesn't sound right.I'd visit the dealer anyway just for peace of mind.

I took mine in for my 10k service last week, and yesterday the temp was also reading 22, even after it had been parked in the sun for ages. i didn't take notice of it this morning though, but i'll check it out on my way home. What was more strange was an irritating ear piercing sound the car was making - it sounded like an annoying electronic frequency coming from the front of the cabin, i could only hear it when the car was off. I left the car parked for about an hour and the sound was gone. Anyone ever had something similar? My car is stock! :confused:

[aaronng]

Sunlight does not affect the outside temperature gauge.
