Q: How do I change the display from Celcius to Fahrenheit?

A: A common question we get is how to set the Dual Controller to Fahrenheit. To do this, follow the steps below: 1. First hold the lower right set key down for about 6 seconds until it flashes E3. 2. Then press the lower right set key 9 times to get to C1 3. Then press the upper left arrow button once to change the display to 01 4. You will see 01 displaying for a few seconds and then it will return to display the temperature in Fahrenheit. KNOWN BUG: The software for this unit has a known bug. When the unit is set to Fahrenheit, it works in Fahrenheit but a small c is displayed, like it is Centigrade mode, on the upper right part of the display. However, the setting is Fahrenheit, and the unit will stay in Fahrenheit mode even if the unit loses power. Also, in Fahrenheit, the unit can only be set to a maximum temperature of 200° F., so if you are using it for distillation mode and want the unit to shut off at say, 203° F. instead of 200° F., you will need to switch to Centigrade so you can program to 95° C which is 203° F.(in Centigrade, the unit can be set to a maximum of 99°).

Q: So if I understand correctly if I am using a digiboil 35l I should only use the 1000w switch when heating (not the two together)

A: Yes, using 1500 watts is a bit much for this control.

Q: Will this work with the high power heating element 1600 watt that I just bought and installed in my kettle?

A: No, the 1600 watt element runs 14.5 amps, and this control has a 10 amp heating relay.

Q: Will this work with only a mini fridge plugged into the cooling plug to keep a constant 33° temp?

A: Providing the Mini Fridge has a robust enough compressor to get down to 33 degrees, it may work. Keep in mind it will not be a constant 33 degrees, as every thermostat has a differential of 3 degrees or so to save the compressor from constant stop and starts. So if you set it at 33, assuming the compressor is powerful enough to get to 33, it will then turn off and rise to 36 degrees before switching on again.
