How do you calibrate the 5-button thermostat?

Likely its kaput. May be try thermostat recalibrate, if this model has option<?>.


THERMOSTAT CALIBRATION
Thermostat readings can vary based on the running environment. If desired the thermostat on the heater can be
manually calibrated. To calibrate the thermostat:
1. Press the TIMER button for 3 seconds to begin calibration.
2. Use the ? ? buttons to adjust the thermostat. The calibration range is -9°F to 9°F (-5°C to 5°C)
3. After 10 seconds without control input the heater will exit thermostat calibration

If youll comment here with exact model name I can research furter.

There is no way to calibrate the thermostat. It is set at the factory with an accuracy range of 2 to 3 degrees. It also can be the location of the thermostat. Even the wall it is mounted on can contribute to heat range. It is also measuring the ambient temperature in the room, which can vary depending on the contents of the room. If it aint broke, don't fix it. It is getting too cold to fiddle with the thermostat.

Hi there!
Using a precision screw driver, turn the thermostat calibration screw counter clockwise to increase the temperature cut-in of the thermostat, it is about 5 degrees celcius per 1/8 turn of the calibration screw.

Try the thermostat on it's lowest setting first. If it doesn't switch off soon enough and gets too cold, you can get different thermostats from your supplier. A bottle fridge thermostat would suit.

I am having the same problem with my Dayton greenhouse thermostat, this question was posted in the wrong section...but if you find a solution I'd like to know. I am having problems with the heating thermostat as well as the cooling one.

Hi there.
You may need to calibrate the new thermostat and in doing so, you will need a calibrated thermometer with sensor dipped in oil at about one (1) inch above the fryer thermostat sensing bulb.
Record the cut-off temp (when indicator light goes off) and compare it with the thermostat setting.
The thermostat has a calibration screw ( - ) recessed in the middle of the shaft, you will see the when you pull off the thermostat knob. this calibration screw can be turned by a precision screw driver, turn clockwise to decrease the cut-off temperature ; turn counterclockwise to increase the cut-off temperature.
Just make sure that the unit is preheated or have cycled at least 5 to 8 times and the oil is new before performing the calibration.
Regards.

You will need to check the oven calibration using a thermocouple based thermometer(the one you stick in the oven is not reliable). Electric ovens should keep a near constant tempature so if you have it set to 350 the oven should stay around 350 once temp is reached. Now gas ovens are a little different. Most use a on/off thermostat and that means the temp can vary from 320 degrees to 370 degrees to keep an average tempature of 350. So if it is a gas oven you will need to let it warm-up for 10 minutes then start taking the lowest and highest 5 consectutive readings. Then add the 5 reads together and then divide the number by 5 and it should be within 10 degrees of the set tempature. If it is off by more than 50 degrees then you might not be able to get it back to proper calibration. The calibration methods are different for each range and depend on the type of thermostat you have digital(push button controls) or manual(knob). The owner's manual for your range might contain the instructions or consult the manufacture's website for the instructions.

Press and hold the bake button for 5 seconds, will go to calibrate mode, press the up or down temp to adjust yiour oven + or - 30'

It's on page 32 of the manual for Thermador's built in convection ovens. 1. turn off the oven 2.touch and hold the start pad and then touch the bake pad 3. 0 (zero) appears in the temp digits. release all pads 4. touch bake and 0 changes in increments. max adjustment is 35 degrees F. 5. to complete change touch start for lower oven on double ovens do this: touch the roast pad instead of the bake pad continue with steps 3-5.
