How to change: Exhaust temperature sensor
How to change the exhaust temperature sensor on your ROEST.
Where to buy temperature sensors?
If you are sure that a temperature sensor in your roaster is broken (you have talked to our Support Team) visit our e-shop to purchase a new one! The exhaust sensor uses the same probe as the BT sensor.

⚠️SAFETY INSTRUCTIONS
make sure the roaster is turned off
the power cord has to be unplugged
follow the steps as instructed below
Tools
10-millimeter wrench
Cutters
Parts
Exhaust temperature sensor
Cable ties
Tray, or similar, to keep removed components
Instructions
Follow this numbered guide below step by step.
3. If your roaster has First Crack detection, you can optionally remove it for easier access. To do so, pull the card gently off the rubber mounts. Leave the cable connected and place the card to one side.
4. Unplug the Exhaust Temperature sensor from the PCB.
5. Cut the cable ties holding the cable in place.
6. Use a 10-millimeter spanner/wrench to loosen the exhaust sensor, and unscrew the sensor from the drum to remove it.
7. Take off the aluminum spacer from the old sensor, and replace it on the new sensor.
8. Screw the new sensor into the back plate by hand until finger tight. NOTE: Please ensure no resistance when rotating so as not to damage the thread in the back plate.
9. Tighten gently with a 10-millimeter wrench. Do not overtighten, as this can strip the thread and scrap the back plate.
10. Feed the cable from the new sensor into position. Pass the cable alongside the other white sensor cables, behind the USB cable, then connect it to the PCB.
11. Tie two new cable ties to the motor bracket where you removed the cable ties earlier.
NOTE: Cable should not touch rotating pulley. This can damage/destroy the sensor over time.
Use cutters to trim excess ends on cable ties.
12. Re-install FC card.
a. Push FC card into position. Pull gently on the ends of the rubber mounts to secure them in place.
b. First Crack card should NOT touch the back plate of the roaster.
24. Install side panels.
26. Plug the roaster in, turn it on and test the exhaust temperature sensor by starting a roast (beans in the machine). You should see the exhaust temperature appear on the graph in live view. If the exhaust temperature doesn’t appear, please double-check the connection to the PCB, and then contact the ROEST support team for help.
