: Press and hold the SET key (or Function key) for approximately 3 seconds to enter the configuration menu for alarms and PID constants.

Heater stays on forever (runs away). Solution: Your output relay might be welded shut, or you have set P (proportional band) to 0 (ON/OFF mode). Change P to 10.0 .

Press the to select the digit you want to change (it will flash). Use Up or Down to adjust the number. Press SET to save the value. xta-7000 temperature controller manual

Typical terminal assignments for the XTA-7000 (96x96mm panel size): Terminals 1 & 2 (Line and Neutral). Control Output (Main): Relay: Terminals 3 & 4 (Normally Open). SSR: Terminal 3 (+), Terminal 4 (-). Sensor Input: Thermocouple: Terminal 9 (+), Terminal 10 (-). RTD (3-wire): Terminals 8, 9, and 10.

Connect the thermocouple or RTD according to the polarity indicated on the device diagram. Use extension wires compatible with the sensor type.

Connect the external load circuit through the Normally Open (NO) and Common (COM) contacts. Use an external contactor if your heating element draws more than 3 Amps. Change P to 10

For a detailed list of all possible error codes, you should consult the official manual for your specific model. The most common cause of an error is a faulty sensor connection.
