Dimplex DWT431W Non-Programmable Thermostat 4000W Owner’s Manual Overview

Summary of Contents

• Page 1: Owners manual for DWT431W non-programmable thermostat 4000W.
• Page 2: Congratulations on your purchase of this Dimplex line-voltage thermostat. Your new thermostat is preprogrammed by the installer and ready to use. Please take the time to read and understand this manual so you can begin to enjoy the convenience this product offers. Features include CSA C828 performance certified, high power up to 4000W, and ideal for baseboard heaters, convectors, radiant ceilings, and electric fan-forced heating systems. Temperature setting and display in °C or °F, manual precise temperature control set in half degrees, and TRIAC system for quiet operation are also included. The thermostat features cycle rates for proportional heating, room temperature and set point temperature display, built-in surge protection, and memory back-up for settings. The setting range is +5°C to +35°C (41°F to 95°F) with a heating power level display and simple 2-wire installation. Specifications include a rating of 120V~240V AC, 60Hz, a maximum load of 16.6A, 4000W @ 240V, and 2000W @ 120V, with a minimum load of 300W @ 240V. Keep this manual in a safe place for future reference.

• Page 4: Installation This product is for use with high voltage systems (120V~240V) with a minimum load of 300W; it is not designed for use with low voltage (24V) central heating & air conditioning systems or wall mounted furnaces. In order to avoid fire, shock or death, shut off power supply at the circuit breaker or fuse and test that the power is off before wiring. This product must be installed in accordance with the Canadian Electrical Code, and in the province of Quebec, by a qualified electrician. Improper installation automatically voids the warranty. Verify that the heating appliance that is being connected is within the specified load range. Confirm voltage is within the device rating. For wiring, use copper conductors only. Must be mounted on a certified electrical box.
• Page 5: Installation Step-by-step installation Remove the old thermostat carefully and identify the two wires from the wall box. Gently remove the faceplate from the right side of the new thermostat. Do not remove the screws from the back of the unit as these screws hold the thermostat together. To remove the faceplate, gently pull the right side of the thermostat. The faceplate should come off easily. Using the wire nuts provided, securely fasten each wire from the new thermostat to a wire in the wall box. Refer to the wiring diagram on the next page. Ensure no bare wire is exposed.
• Page 6: Installation Step-by-step installation Mount the new thermostat onto the wall box using the two screws provided through the mounting holes, and then replace the faceplate. If mounting on a single gang box, use the two mounting holes on the left side, in order to avoid fire or shock. Reconnect power supply.

• Page 8: Operation Selecting the temperature unit (°C or °F) This thermostat features an adjustable display setting that can display the temperature in either Celsius or Fahrenheit. To enter the setting mode, press the UP and DOWN buttons at the same time for 3 seconds. The screen will display CR (cycle rate) and a number on the bottom pane along with the Fahrenheit or Celsius temperature reading on the top pane. Press the UP button to toggle between the °C or °F display. The default temperature unit is °C. Every time the temperature unit is changed, the thermostat will revert to the default temperature setting: 20.0°C or 68.0°F. Selecting the heat cycle rate This thermostat has an adjustable heat cycle rate to provide precise, consistent, and economical heating. The cycle rate determines the on/off time cycles that the thermostat uses to reach and maintain the desired temperature. Selecting the correct cycle rates helps maintain an even temperature, which reduces energy usage while improving comfort.
• Page 9: Operation Selecting the heat cycle rate While in the setting mode, press the DOWN button to toggle between the various cycle rates. There are 3 different cycle rates to choose from: Cr-0, Cr-1, Cr-2. Cr-0 is a fixed span (no cycling), with a variance of +/- 0.3°C (+/- 0.6°F). Cr-1 (Default) is a 20 second cycle rate with proportional heating. Cr-2 is a 240 second span, meaning the heating will be turned on and off once every 240 seconds. Cr-0 is recommended for users who do not want their electric heating devices turning on and off frequently. Cr-1 is recommended for non-fan assisted baseboards and electric heating devices. Cr-2 is the recommended setting for fan assisted heaters, radiant ceilings, and convectors.
• Page 10: Operation Adjusting the desired set temperature The current room temperature is normally displayed on the LCD screen. To adjust the setting to the desired set temperature, press the UP or DOWN button. The temperature can be set in increments of 0.5°C or 0.5°F. The temperature setting range is from 5°C to 35°C (41°F to 95°F). Tip: Press and hold the UP or DOWN button to change the setting more rapidly.
• Page 11: Operation Heating power level display When the thermostat activates the heating system, the Heat On symbol will appear. Equipped with an intelligent proportional regulation system, this thermostat will determine the amount of power needed by the electric heater to maintain the room temperature at precisely the set temperature. The Power Bar (A) will indicate the current output power level. 1 BAR = 20% and 10 BARS = 100%
• Page 12: Troubleshooting The LCD screen is blank or abnormal. Make sure the thermostat is fully installed. Check that the power supply has been reconnected at the circuit breaker or fuse. If the heater or heating appliance has a power switch of its own, check to see that it is in the ON position. The thermostat housing feels hot to the touch. When working at full capacity, the thermostat housing may reach a temperature of approx. 45°C to 50°C (113°F to 122°F). This is normal and does not affect the operation of the thermostat. LCD bottom pane is blinking. If no button is pressed for 16 seconds, the display will automatically return to the “current temperature mode.” Temperature setting will not change. Make sure the temperature is set to the acceptable range: 5°C to 35°C (41°F to 95°F).
