So I spoke to Autoterm this morning and ran through the settings, think I was being a bit impatient, apparently it will run for a minimum of 40mins at full on start up to help stop coking up and as others have said, the numbers are arbitrary as the heater will only cut out at 5° above and kick in 3° below the set temp. Left it running for a good hour at 16° and warmed up nicely then calmed down, although there is still a reasonable amount of noise from the inlet in the drivers step, is this due to the ventilation setting?
The noise from the step is the sound of the motor and combustion echoing up the duct, no cure for this that I know of except maybe a soft soundproofing lining to the inlet duct.
My 4Kw Webasto is the same, it was near silent when on test in the workshop and I reckon that the noise increased more than tenfold.

Haven’t had my seats or slim units fitted yet, soon as it’s in that will be extended and relocated
I am due to get my Planar fitted next week and decided to downgrade to the PU-5 controller. Going to be positioning this waist high (I have no pop-top) and in the middle of the van. Looking at upgrading to the comfort controller when it becomes available.
Thats a convenient user location for the controller.....
I hope they have not set it to use the stat on the controller
Had a van in with a Webasto controller positioned there the other day, not exactly convenient. looks Like the installer couldn’t be bothered, also I suggest changing that vent to prevent debris finding its way in and downThats a convenient user location for the controller.....

I have installed my planar heater with a standard pu27 controller. Set the T setting to T panel and ventilation off. I set the temperature to 17degree overnight But i have noticed that the heater doesnt go off when the set temp is reached and i have been woken up in the middle of the night by the heat in the van. On both occasions the van went up to 27dgree. Any ideas what the problem is or am i missing something on thr setting menu?

Try setting it a lot lower 8/9 degrees say - the air entering the heater will still be attempting to reach 17 degrees at floor level when it has started cooking you at mid height in the van.

Just finished installing mine...Really pleased with its performance.. The digtal controller is easy to use
I am also trying to figure out exactly how the pu27 works.
The pu27 has a temp sensor on the control panel in my van, which is mounted half way up the b pillar.
I have set the timer to stay on all night at 18 degs. The manual says the heater will kick in 5 degs Lower than that. Will it then switch off once it gets back up to 18?
The instructions aren't straight forward!
EDIT: the instructions say the heater will only run for 2 hours at a time.
So do I then need to set the timer to come on again?

Exactly why I opted for the PU-5.....
You can get a remote temp sensor which you can position wherever you want. I've got mine at the same level as my exploria bed.....its almost invisible against the carpet wall
Planar Pete - what a helpful guy.
I didn't actually buy the heater from him but gave me 10 mins of his time on the phone to explain how to use the Pu27 controller.
He recommended just leaving the heater running all night on low fan speed with a window cracked slightly; which stops the heater stopping/starting all night which is noisier.
However he said the thermostat mode is also fine but not to use the control panel temp sensor, but the internal heater temp sensor to keep things more consistent.
Sounds like I need to do some more trial and error.

I'm interested to hear from those who have upgraded from the PU-27 to the comfort controller. Slick interface aside, is the comfort controller better at controlling temperature about a setpoint? Does the adjustable hysteresis of the comfort controller make real difference? Is the PU-27 on/off control, or does it also vary power output to hone in on a setpoint?
