1. المقدمة
The QuietWarmth THERMST-D Non-Programmable Thermostat is designed to provide reliable control for 120V or 240V electric radiant floor heating systems. This thermostat offers flexible temperature management, allowing you to configure it for control based on floor temperature, room temperature, or a combination of room temperature with a floor temperature limit. It features a built-in Ground Fault Circuit Interrupter (GFCI) for enhanced safety and a clear, backlit display for easy monitoring and operation. A floor sensor is included to ensure accurate temperature readings and optimal comfort.

2. معلومات السلامة
Please read all instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or property damage.
- تحذير: To reduce the risk of electric shock, do not connect this device to a circuit with any phase operating down more than 150 volts to ground.
- يجب أن يتم التركيب بواسطة كهربائي مؤهل وفقًا لقوانين الكهرباء المحلية والوطنية.
- The thermostat requires connection to a dedicated 20 Amp دائرة كهربائية.
- The resistive load connected to the thermostat must not exceed 15 Amps.
- Electric radiant floor heating systems are required by the National Electrical Code to be protected by a Ground Fault Circuit Interrupter (GFCI). This thermostat has a built-in GFCI.
- Always turn off power at the circuit breaker before installing or servicing the thermostat.

5. الإعداد والتثبيت
يجب أن يتم إجراء التثبيت بواسطة كهربائي مؤهل فقط.
5.1 التركيب
- The thermostat is designed for wall mounting.
- Ensure the mounting location is free from direct sunlight, drafts, or other heat sources that could affect temperature readings.
5.2 الأسلاك
Before wiring, ensure power is OFF at the circuit breaker.
- Connect the thermostat to a dedicated 20 Amp دائرة كهربائية.
- Identify the Line (power supply) and Load (heating mat) wires.
- Connect the Line wires to the L1(L) and L2(N) terminals on the thermostat's back panel.
- Connect the Load wires from the heating mat to the 'Load' terminals on the thermostat.
- تأكد من التأريض المناسب وفقًا للقواعد الكهربائية المحلية.
- The thermostat is dual-voltage; it can be used with either 120V or 240V heating mats, but not simultaneously. Verify your heating mat's voltage يطابق مصدر الطاقة.
5.3 Floor Sensor Placement
The floor sensor is crucial for accurate floor temperature control.
- Place the sensor next to the long edge of the QuietWarmth heating mat.
- Ensure the sensor is positioned in the heated area and not near any unheated zones or external heat sources.
- Route the sensor wire carefully to avoid damage during installation of flooring materials.

6. تعليمات التشغيل
6.1 تشغيل
After installation, restore power at the circuit breaker. The thermostat display will illuminate.
6.2 ضبط درجة الحرارة
- استخدم Up و تحت أزرار لضبط درجة الحرارة المطلوبة.
- اضغط على OK زر لتأكيد اختيارك.
أوضاع التحكم 6.3
The thermostat can be configured to operate in one of three control modes:
- Floor Temperature Control: The thermostat maintains the floor at the set temperature using the floor sensor.
- التحكم في درجة حرارة الغرفة: The thermostat maintains the room air temperature at the set point.
- Room Temperature Control with Floor Limit: The thermostat primarily controls room air temperature but prevents the floor temperature from exceeding a specified maximum limit, protecting sensitive flooring materials.
Refer to the full installation guide for instructions on how to select and configure these control modes.
6.4 Energy Log
The thermostat features a seven-day energy log, allowing you to monitor the power consumption of your radiant heating system. Consult the detailed manual for accessing and interpreting this data.
7. الصيانة
7.1 اختبار قاطع التيار الأرضي
For continued safety, the built-in GFCI should be tested monthly.
- اضغط على امتحان button located on the bottom of the thermostat.
- The GFCI should trip, cutting power to the heating system and indicating a fault.
- اضغط على إعادة ضبط button to restore power.
- If the GFCI does not trip or reset correctly, discontinue use and contact a qualified electrician.

8. استكشاف الأخطاء وإصلاحها
If you encounter issues with your QuietWarmth THERMST-D thermostat, refer to the following common problems and solutions:
- لا يوجد عرض/لا يوجد طاقة:
- Check the circuit breaker for the dedicated circuit and ensure it is in the ON position.
- تأكد من أن جميع توصيلات الأسلاك آمنة وصحيحة.
- نظام التدفئة لا يعمل:
- Ensure the thermostat is set to a temperature higher than the current room or floor temperature.
- Check if the GFCI has tripped (press the RESET button if it has).
- Confirm the correct control mode is selected (floor, room, or room with limit).
- GFCI Trips Frequently:
- This indicates a ground fault. Immediately turn off power at the circuit breaker.
- Inspect the heating mat and wiring for any damage or moisture.
- Ensure the total resistive load does not exceed 15 Amps.
- Contact a qualified electrician for diagnosis and repair.
- قراءات درجة الحرارة غير دقيقة:
- Verify the floor sensor is correctly installed and not damaged.
- Ensure the thermostat is not exposed to drafts, direct sunlight, or other external heat sources.
For issues not covered here, please contact QuietWarmth customer support or a qualified electrician.
