Installation

Before you begin the installation process, ensure you have all the necessary tools and materials, including a screwdriver, wire strippers, and appropriate electrical wiring. It is crucial to disconnect the power supply to your boiler or central heating system before commencing any installation work. The Digistat SCR receiver unit should be mounted in a convenient location, close to the boiler or central heating system wiring center. This placement will minimize the length of wiring required and ensure easy access for future maintenance or troubleshooting. When choosing a location, consider factors like proximity to existing wiring, accessibility for programming, and potential interference from other devices. Avoid mounting the SCR in areas with high humidity or direct sunlight.

The SCR is wired into the Combi boiler or conventional system using the provided terminal block. Carefully connect the wires according to the wiring diagram provided in this manual. Ensure that all connections are secure and properly insulated. Once the wiring is complete, reconnect the power supply to your boiler or central heating system and test the functionality of the Digistat SCR. Verify that the unit is receiving power and responding correctly to the Digistat RF thermostat. Refer to the troubleshooting section in this manual if you encounter any issues during the installation process.

Commissioning

Commissioning the Digistat SCR involves setting up the wireless communication between the Digistat RF thermostat and the SCR receiver unit. This process ensures that the thermostat can effectively control the heating system. Begin by installing the Digistat RF thermostat according to the provided instructions. Once the thermostat is installed, power on the boiler or central heating system and allow the SCR receiver unit to initialize. You will likely see an LED light on the SCR unit indicating that it is powered up and ready for commissioning.

Next, you will need to put the SCR unit into “learn mode.” This mode allows the SCR unit to recognize the unique signal from the Digistat RF thermostat. The process for entering learn mode varies depending on the model of the Digistat SCR. Refer to the specific instructions for your model in the user manual. Once in learn mode, the SCR unit will be ready to pair with the Digistat RF thermostat. Press the “Learn” button on the Digistat RF thermostat, and the unit will emit a signal to the SCR receiver. The SCR unit should acknowledge the signal by blinking its LED light or displaying a confirmation message. Once the pairing is successful, the Digistat SCR will be commissioned and ready to control your heating system.

Operation

Once the Digistat SCR is commissioned, it’s ready to operate with the Digistat RF thermostat to control your heating system. The Digistat RF thermostat will send wireless signals to the SCR unit, which in turn will activate or deactivate the heating system based on the temperature settings. The Digistat RF thermostat provides various features to manage your heating, including a programmable timer, a manual override function, and a frost protection setting.

Using the programmable timer on the Digistat RF thermostat, you can create a schedule for your heating system to turn on and off at specific times throughout the day and week. This allows you to optimize your heating schedule for energy efficiency. The manual override function allows you to temporarily adjust the temperature settings or turn the heating on or off, regardless of the programmed schedule. This is useful if you need to make quick adjustments to the temperature, for example, if you are experiencing a cold snap or if you are away from home for an extended period. The frost protection setting ensures that the heating system will turn on automatically if the temperature drops below a certain threshold, preventing pipes from freezing.

Troubleshooting

If you encounter any issues with your Digistat SCR, refer to the following troubleshooting steps. First, ensure that the Digistat RF thermostat is properly paired with the SCR receiver. Check the red LED on the Digistat RF to confirm a strong signal. If the LED is not flashing, reposition the thermostat until the signal is strong. If the heating system fails to turn on despite a strong signal, check the power supply to the SCR.

Examine the wiring connections to ensure they are secure and properly connected. If the heating system turns on but does not reach the desired temperature, verify the thermostat settings. Ensure the desired temperature is correctly set and that the heating system is set to the correct mode, such as “heating” or “auto.” If the problem persists, check for any blown fuses or tripped circuit breakers. Finally, if the issue cannot be resolved through these steps, contact a qualified electrician for assistance.

Manual Override

The Digistat SCR features a manual override function that allows you to manually control the heating system in the event of a fault or if the Digistat RF thermostat is not functioning correctly. To manually override the system, locate the OVERRIDE button on the SCR receiver. Pressing this button will turn the heating system on or off, regardless of the settings on the Digistat RF.

The red LED on the SCR will illuminate to indicate that the manual override mode is active. To deactivate the manual override, simply press the OVERRIDE button again. The heating system will then revert to the settings on the Digistat RF. It’s important to note that the manual override function should only be used temporarily. If you find yourself needing to use manual override frequently, it may indicate an underlying issue with the Digistat RF or the heating system itself. In such cases, it is recommended to consult a qualified electrician for troubleshooting and repair.

Programming

Programming the Drayton Digistat SCR is a straightforward process that allows you to customize the heating system to meet your specific needs. The programming options can be accessed through the Digistat RF thermostat. To begin programming, you will need to consult the user manual for the Digistat RF. It will provide detailed instructions on how to access the programming menu and navigate through the various settings;

You can adjust parameters such as the desired room temperature, heating schedule, and other settings that control the operation of the heating system. The programming menu is typically user-friendly and allows you to make changes with ease. However, it’s crucial to read the user manual carefully before attempting any programming modifications. This ensures that you understand the function of each setting and avoid any errors that might affect the performance of the heating system. Regularly reviewing the programming settings can help you optimize energy efficiency and create a comfortable living environment.
