QuietWarmth THERMST-D Non-Programmable Thermostat User Manual

1. Introducció

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. Informació de seguretat

Please read all instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or property damage.

• ADVERTIMENT: 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.
• La instal·lació ha de ser realitzada per un electricista qualificat d'acord amb les normes elèctriques locals i nacionals.
• The thermostat requires connection to a dedicated 20 Amp circuit
• 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. Configuració i instal·lació

La instal·lació només l'ha de dur a terme un electricista qualificat.

5.1 Muntatge

• 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 Cablejat

Before wiring, ensure power is OFF at the circuit breaker.

1. Connect the thermostat to a dedicated 20 Amp circuit
2. Identify the Line (power supply) and Load (heating mat) wires.
3. Connect the Line wires to the L1(L) and L2(N) terminals on the thermostat's back panel.
4. Connect the Load wires from the heating mat to the 'Load' terminals on the thermostat.
5. Assegureu-vos de connectar a terra correctament d'acord amb els codis elèctrics locals.
6. 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 coincideix amb la font d'alimentació.

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. Instruccions de funcionament

6.1 Encès

After installation, restore power at the circuit breaker. The thermostat display will illuminate.

6.2 Configuració de la temperatura

• Utilitza el Up i Avall botons per ajustar la temperatura desitjada.
• Premeu el botó OK botó per confirmar la selecció.

6.3 modes de control

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.
• Control de la temperatura de l'habitació: 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. Manteniment

7.1 GFCI Testing

For continued safety, the built-in GFCI should be tested monthly.

1. Premeu el botó PROVA button located on the bottom of the thermostat.
2. The GFCI should trip, cutting power to the heating system and indicating a fault.
3. Premeu el botó RESET button to restore power.
4. If the GFCI does not trip or reset correctly, discontinue use and contact a qualified electrician.

8. Solució De Problemes

If you encounter issues with your QuietWarmth THERMST-D thermostat, refer to the following common problems and solutions:

• Sense pantalla/Sense alimentació:
  • Check the circuit breaker for the dedicated circuit and ensure it is in the ON position.
  • Verifiqueu que totes les connexions de cablejat siguin segures i correctes.
• Heating System Not Activating:
  • 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).
• Freqüència dels desplaçaments GFCI:
  • 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.
  • Poseu-vos en contacte amb un electricista qualificat per a un diagnòstic i una reparació.
• Lectures de temperatura inexactes:
  • 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.
