General Notes
1. In order to reduce external interference, it is recommended to use twisted pair or shielded wire as the control line of RS485.
2. SSR should adopt random-on type, zero-crossing SSR cannot be used.
3. Isolating thermocouples are preferred. In order to improve the accuracy of temperature detection, it is recommended to choose a shielded thermocouple.
