Air con and heating

[MB1]

Hi
I am new to the Bongo and wanted to ask before my user manual arrives an air con question. Does the air con system also work to deliver hot air from a cold engine (before the engine warms up)? Mine seems to blow hot only when the engine is hot.

Also, when I set the temp to 18degC on an auto climate unit the blowers are on full, when I then set it to 18.5 or more the blowers turn off. If I control the fan speed away from auto air con control then the blowers are adjustable. Is this normal?

In your hands

Perfectly normal my friend. At 18 degrees you are asking the unit to give you the coldest temp it can.
At 18.5 it will reduce the temp to 18.5 then relax, safe in the knowledge that it has delivered your request.
I always press the desired temp, press the auto button then turn off the aircon by pressing ac twice. This enables automatic temp setting, but spares the engine having to work too hard to maintain temp with the aircon on.
As for the heating thing. Heaters gain their temp from the water circulating in the engine, through the heater matrix (Keano Reeves invented this). If the water travelling through the matrix (In slow motion with bullets passing by) is cold, then the heater has to wait until the engine has warmed before it can fulfill your wishes.

One last thing. Never ever, with a climate control vehicle, attempt to put the front on cold climate and the rear on a warm climate.
This will result in a coming together of a cold climate and a warm climate and will result in high wind, flash floods and a tsunami. Thunder and lightning are very distracting whilst driving.

Hope this helps

Regards,

Big Dave

Great
Thanks Big Dave
I had thought that the heating came through the AC heat exchanger unit by some magic but I guess it too has to wait for the engine to warm up.
