DIGITEN WTC200 Wireless Temperature Controller Thermostat Outlet Instruction Manual

1. Introduction

The DIGITEN WTC200 is a wireless temperature controller thermostat outlet designed to automatically manage heating or cooling devices based on a preset target temperature. This system consists of a remote control unit and a receiver outlet with an integrated temperature sensor. It offers convenient remote operation and precise temperature monitoring for various applications.

Key features include:

• Wireless Remote Control: Allows for setting and controlling temperatures from a distance of 50-100 meters in open areas.
• Heating and Cooling Modes: Supports both heating and cooling appliances.
• LCD Display with Backlight: Provides clear temperature readings and settings, visible even at night.
• Temperature Sensor: An accurate NTC temperature sensor is integrated into the receiver outlet to detect ambient temperature.
• High/Low Temperature Alarms: Configurable alarms to alert users of temperature deviations.
• Memory Function: All settings are retained even after a power failure.
• Energy Efficiency: Helps save energy by activating connected appliances only when necessary to maintain the target temperature.

2. Setup

2.1 Unpacking and Component Check

Before beginning, ensure all components are present:

• DIGITEN WTC200 Remote Control
• DIGITEN WTC200 Receiver Outlet with 2m/6ft NTC Temperature Sensor Probe

2.2 Battery Installation (Remote Control)

The remote control requires two (2) 1.5V AAA batteries (not included). Open the battery compartment on the back of the remote and insert the batteries, observing the correct polarity.

2.3 Connecting the Temperature Sensor

The NTC temperature sensor probe is integrated into the receiver outlet. Ensure the probe is securely connected to the receiver outlet. The temperature is detected by this sensor on the outlet unit.

2.4 Initial Pairing

The remote control and receiver outlet are typically pre-paired. If re-pairing is necessary or if you are using multiple units:

1. Ensure the receiver outlet is plugged into a power source.
2. To prevent interference when pairing multiple units, remove batteries from any other remote controls and ensure only one remote is powered on and active during the pairing process.
3. Refer to the specific pairing instructions in the full manual if the units do not communicate automatically.

3. Operating Instructions

3.1 Powering On/Off

Press the power button on the remote control to turn the unit on or off. The LCD screen will illuminate when powered on.

3.2 Setting the Target Temperature

1. Press the 'SET' button on the remote control. The target temperature display will flash.
2. Use the 'Up' and 'Down' arrow buttons to adjust the desired target temperature.
3. Press 'SET' again to confirm the setting, or wait a few seconds for it to automatically save.

3.3 Switching Between Heating and Cooling Modes

The WTC200 supports both heating and cooling operations. The mode determines whether the connected appliance turns on when the temperature falls below (heating) or rises above (cooling) the set point.

3.4 Changing Temperature Units (Celsius/Fahrenheit)

The unit can display temperature in either Celsius (℃) or Fahrenheit (℉). Refer to the full manual for specific button combinations to switch between these units. Typically, this involves a long press of a specific button or a combination of buttons.

3.5 Setting High/Low Temperature Alarms

The WTC200 features configurable high and low temperature alarms. When the ambient temperature exceeds the high alarm limit or drops below the low alarm limit, the unit will trigger an alert.

1. Access the alarm setting menu (refer to the full manual for specific button presses).
2. Adjust the desired high and low temperature thresholds using the arrow buttons.
3. Confirm the settings.

3.6 LCD Display with Backlight

The remote control's LCD screen features a backlight for improved visibility, especially in low-light conditions or at night.

4. Maintenance

4.1 Cleaning

To clean the device, use a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the unit in water. Ensure the device is unplugged before cleaning the receiver outlet.

4.2 Battery Replacement

When the remote control's display indicates low battery, replace the two (2) 1.5V AAA batteries promptly to ensure continuous operation and accurate readings. Using high-quality alkaline batteries is recommended for optimal performance and battery life.

5. Troubleshooting

5.1 Remote Control Not Responding

• Check Batteries: Ensure the remote control has fresh 1.5V AAA batteries and they are inserted with correct polarity.
• Range: Verify the remote is within the effective transmission range (50-100m in open areas) of the receiver outlet. Obstacles like thick walls can reduce this range.
• Interference: If using multiple WTC200 units, ensure only the remote you intend to pair or use is active during setup to avoid signal interference.

5.2 Inaccurate Temperature Readings

• Sensor Placement: Ensure the temperature sensor on the receiver outlet is not obstructed or exposed to direct heat/cold sources that do not reflect the ambient temperature you wish to measure.
• Fahrenheit/Celsius Conversion: Note that while the display can show Fahrenheit, the internal control logic may operate in Celsius. This can lead to slight discrepancies when setting a precise Fahrenheit temperature, as the system converts it to Celsius for control. For example, setting 70.0°F might result in control around 21.0°C (69.8°F).

5.3 Short Battery Life

Some users have reported shorter than expected battery life. To mitigate this:

• Use high-quality alkaline batteries.
• Avoid using rechargeable NiMH batteries, as their voltage characteristics may not be optimal for this device.

5.4 Display Orientation

The remote control's display may appear inverted depending on how it is held or mounted. This is a design characteristic; the display is optimized for viewing when placed on a flat surface or mounted at a certain height.
