4.1. Montavimas

Mount the controller in a location that is easily accessible for viewing and adjustments, away from direct heat sources or excessive vibration. Ensure the chosen location is appropriate for the controller's enclosure type (NEMA 1 for indoor use, NEMA 4X for outdoor or wash-down environments). Use appropriate fasteners to secure the unit firmly.

4.2. Laidai

All wiring must comply with local and national electrical codes. It is recommended that a qualified electrician perform the installation.

1. Atjunkite maitinimą: Ensure all power to the circuit is disconnected before beginning any wiring.
2. Maitinimo įvestis: Connect the appropriate line voltage (120V, 208V, or 240V AC) to the designated power input terminals on the controller.
3. Apkrovos išvestis: Connect the controlled device (e.g., compressor, heater) to the output relay terminals. Observe the maximum current ratings (16 Amps @ 120V AC, 8 Amps @ 208/240V AC).
4. Jutiklio jungtis: Connect the temperature sensor lead to the sensor input terminals. The 8-foot sensor lead can be extended up to 400 feet using 18 or 22-gauge thermostat wire. Ensure all connections are secure and properly insulated.
5. Įžeminimas: Properly ground the controller according to electrical codes.

5. Naudojimo instrukcijos

The ETC-141000-000 features an intuitive interface for setting and monitoring temperature.

5.1. Initial Power-Up and Basic Settings

Upon initial power-up, the controller will perform a self-test. Follow the easy 4-step set-up process outlined in the quick start guide (typically included with the product) to configure basic parameters.

5.2. Setting Temperature (Setpoint)

1. Paspauskite NUSTATYTI button once. The current setpoint will flash on the display.
2. Naudokite UP or ŽEMYN arrow buttons to adjust the setpoint to the desired temperature.
3. Paspauskite NUSTATYTI button again to confirm and save the new setpoint, or wait a few seconds for it to automatically save and return to normal operation.

5.3. Selecting Heating/Cooling Mode

The controller can operate in either heating or cooling mode. Refer to the detailed programming instructions in the full manual for specific steps to switch between these modes. This setting determines whether the output relay activates when the temperature rises above or falls below the setpoint.

5.4. Differential Adjustment

The differential (also known as hysteresis) prevents rapid cycling of the controlled device. To adjust the differential (range 1°F to 30°F):

1. Access the advanced programming menu (refer to the full manual for specific button combinations).
2. Navigate to the differential setting parameter.
3. Naudokite UP or ŽEMYN arrow buttons to set the desired differential value.
4. Save the setting and exit the programming menu.

5.5. Klaviatūros blokavimas

To prevent unauthorized changes to settings, the keypad can be locked. Consult the full instruction manual for the specific procedure to enable and disable the keypad lockout feature.

6. Priežiūra
