6. Operating Instructions
Once installed and powered, the EVCO EVX003N7XXBXX02 regulator will display the current temperature measured by the NTC probe. The operation typically involves setting the desired temperature (setpoint) and configuring control parameters.
6.1. Setting the Setpoint
- Press the SET button (or equivalent) to enter setpoint adjustment mode.
- Use the UP and DOWN arrow buttons to adjust the desired temperature value.
- Press SET again to confirm and save the new setpoint.
6.2. Accessing Parameters
Advanced parameters (e.g., hysteresis, probe calibration, alarm settings) are usually accessed via a combination of button presses or a long press on a specific button. Consult the full technical manual for a complete list of parameters and their functions.
- Typically, a long press (e.g., 3-5 seconds) on the SET button or a dedicated PRG (Program) button will grant access to the parameter menu.
- Navigate through parameters using UP and DOWN buttons.
- Press SET to view/edit a parameter value.
- Press SET again to save the change.
- Exit the parameter menu by pressing a specific EXIT button or by waiting for a timeout.
Note: Specific button functions and parameter codes may vary. Always refer to the detailed programming manual for comprehensive instructions.
