Be Careful:

1. The default support for the temperature controller is PT100 platinum resistor. If a PT1000 platinum resistor needs to be used together, the reference resistance of the temperature controller needs to be changed from 402 ohms (4020) to 4.02K ohms (4021), with an accuracy of 0.1% and a closed 0805. Please refer to the attached wiring manual for details.

2.The temperature controller is compatible with 2-wire/3-wire/4-wire platinum resistors by default. The connection methods between them and the temperature controller are different, and they need to be switched by changing the jump cap on the temperature controller. Please refer to the attached wiring manual for specific wiring methods.
