SmarTemp 3.0 & TP90

Scott was a pleasure to work with, he was knowledgeable and willing to help. He reviewed Tech documents and provided suggestions and ultimately got me TP90 coolant heater working as Webasto intended with the SmarTemp 3.0 providing Bluetooth controllability

I would highly recommend VMACS!

Thanks Scott !!

Works great!

Was having difficulties with my EVO 45 shutting down, error code indicated it was the controller. Replaced V2.0 to V3.0 BT - the diagnostics are great with V3.0. Determined it was faulting due high exhaust temp. Cleaned it up and now works great.

Power consumption

Is it possible, using the Smartemp 3.0 to start the heater and keep it on for the entire night. On and off cycling during the night drains my batteries completely because of the glow plug energy consumption. I currently have a rheostat to control the unit

The Smartemp 3.0 is designed to work similar to a household thermostat. The heater will try to maintain the exact temperature set on the control. Therefore, it will also cycle unless it is so cold that the heater can never fully meet demand which will cause it to run continuously in an attempt to do so.

The heater is designed to work with your vehicle battery. It should never drain your battery completely. The heater has a built in, low voltage safety. If it detects a supply voltage below 10.5v it will shut down to prevent draining the vehicle battery too much. Additionally, if it not already in operation, the heater will not start if the voltage is below the threshold.

You may need to have a load test done on your batteries to check their condition.

Good idea, mediocre execution

The SmarTemp 3.0 is Webasto's attempt to enter the 21st century. While not wifi-enabled as many would expect for a new product launched in 2022, bluetooth is a good start. Unfortunately, it still falls short in a few key ways. Firstly, on my unit, the screen was mounted crooked; it's tilted about 10º up and to the right. This is annoying but doesn't impact functionality. Secondly, the unit has a built-in temperature probe that it uses to display the ambient temperature, but it doesn't actually use this temperature to determine the target heat temp. Instead, it seems to be relying on the internal probe of my Air Top Evo 55. I know this because of the excellent diagnostic information available over the bluetooth connection and the iPhone app – that's the best part of the device.

Coming from the MultiControl it was a worthwhile upgrade for me, but if I had the standard dual dials I wouldn't bother.

VMACS was awesome as always.
