WHEN REPLACING A DYNATROL: CHECK THE CONFIGURATION OF THIS REPLACEMENT CONTROL TO MAKE SURE YOU DON’T MELT YOUR KILN!
A replacement DynaTrol control will typically have our standard configuration for Type K thermocouples, 18 Deg F thermocouple offset, and 3 zone control. THIS MAY NOT MATCH YOUR KILN! Here is what you need to check:
CHECK THE THERMOCOUPLE TYPE
- This is the MOST IMPORTANT thing to do. If your kiln has type S thermocouples and the control is set up for type K thermocouples, you could overfire the kiln to the point of a complete melt-down.
- Type K thermocouple extension wire (the wire that goes from the thermocouple to the control) is either yellow or brown. Type S extension wire is green (in the USA).
- See this for more information on thermocouple wires and hookup: check-polarity-thermoocuples-and-lead-wires
Type K thermocouples typically look like this.
Type S thermocouples typically look like this.
HOW MANY ZONES DO YOU HAVE?
- Count the number of thermocouples you have – that should equal the number of zones configured in the DynaTrol.
- The change the number of zones that the DynaTrol is configured for see these instructions:

CHECK THE THERMOCOUPLE OFFSET
- If you have Type S thermocouples then the Thermocouple Offset should be set for 00.00.
- If you have Type K thermocouples and there is a ceramic protection tube then the Thermocouple Offset should be typically be set for 00.18 (18 Deg F).
- If you have Pyrocil sheathed Type K thermocouples or 14 gauge or 8 gauge thermocouples without a ceramic protection tube then the Thermocouple Offset should be set for 00.00
