A thermostat is a control device, which requires sensors capable of gathering external signals. Consequently, thermostats have an input terminal. Depending on the model of the thermostat, there will be different requirements for voltage and the number of connections. Always ensure you understand the thermostat's wiring requirements before making any connections.

1. Open the cover of the electric heating cable temperature controller, unscrew the connector, and then each cable from the incoming line box passes through the connector, clamp, and rubber seal before entering the wiring chamber.

In a single-phase system with working voltages of 220V, 380V, or 110V, connect one core wire from the incoming and outgoing lines to the "T1" and "T2" terminals, respectively. The remaining incoming line and one outgoing line are connected to the "short-circuit" terminal, then tighten the connector sleeve and secure the terminal cover screw.

3. Open the temperature control box lid, align the medium process temperature number on the dial with the red reference dot on the core strip, and then tighten the box lid screw.

4. Secure the box seat with pipe clips to the appropriate location on the pipeline (usually near the electrical heating trace power junction box), and apply the temperature sensing probe to the surface of the pipeline with a heat-resistant adhesive tape. The temperature sensing package should be firmly attached to the area of the pipeline being measured using aluminum foil tape, and then secured with a heat-resistant adhesive tape. The installation site of the temperature sensing probe should be kept away from the electrical heating trace to prevent accidental operation.

5. The power cable is connected to the power grid, and the control cable is connected through a explosion-proof power junction box to the electric tracing heater, and the inspection confirms no issues.
