W1209 Digital Thermostat Relay Usage:

Once you press the Set button, the screen will start to flash. You can adjust the temperature of the relay by pressing the + and - buttons if you want it to open its contacts.

Long press on the set button will enter the main menu. You can switch between P0-P6 menus with + and - buttons. You have to press the set button once to enter the menu you want. After entering the menu, you must use the +/- buttons to adjust the value. You can return after waiting for a while or by pressing set or exit the menu by long pressing. The functions of the P0-P6 menus are as follows:

• P0: Cooling / Heating; Range: C / H; Default: C
• P1: delay setting; Range: 0.1-15; Default: 2
• P2: the highest temperature; Range: 110 ° C; Default: 110
• P3: lowest temperature; Range: -50 ° C; Default: -50
• P4: Temperature Correction (calibration); Range: -7 / 7 ° C; Default: 0 ° C
• P5: delay start time; Range: 0-10 MIN; Default: 0
• P6: Key Tone Switch; Range: 0-110; Default: Off

Örnek ayar: Set butonuna uzun bastığımızda ekranda P0 yazar. "+" butonuna 6 kere bastığımızda P6 yazar ve set'e basarak P6 menüsüne gireriz. Default ayarı 110 olduğundan ekranda 110 yazar. "-" butonuyla değeri 40'a düşürüp set'e uzun basarak ayarı yapmış oluruz. Böylece sıcaklık 40 dereceye ulaştığında buzzer ötmeye başlayacaktır.
