Frequently Asked Questions
Here are some frequently asked questions about this product:
How exactly does the “AUTO Operation (Automatic)” function work on the Siemens RDJ 100 FR/SET thermostat?
You have 4 events. When the thermostat is set to automatic mode, it follows the set times. Here’s an example of programming:
- A1 turns on (6:00 in the morning)
- A2 turns off (8:00 in the morning)
- A3 turns on (5:30 in the evening)
- A4 turns off (10:00 in the evening)
The thermostat switches between the two Comfort and Economy temperatures automatically.
What is the difference between the “Comfort Temperature adjustment (T Sun)” and the “Economy Temperature adjustment (T Moon)”?
You can interpret the two temperatures in this way:
- Sun Temperature: To be used when the apartment is occupied, so during the day. You can think of it as the ‘on’ temperature.
- Moon Temperature: To be understood as the ‘off’ temperature, you can certainly use it during the night and during a specific time frame in the day.
How can I ensure that my set temperature is not overridden during the next event?
If you use the manual function for extended periods, we suggest you set the left selector to the Permanent Comfort position.
How do I know when it’s time to replace the thermostat batteries?
A low battery symbol appears on the display, alerting you it’s time for a change. The device will, however, still function for a short while.
Can I use rechargeable batteries for the RDJ 100 FR/SET thermostat?
We strongly advise against using them, as the thermostat communicates via radio waves with the receiver and requires a good charge that rechargeable batteries might not provide.
How does the RDJ 100 FR/SET thermostat handle frost protection mode?
If the thermostat is set to OFF (from the left selector), it’s not completely turned off. If the room temperature drops to 8 degrees Celsius, the thermostat will heat the environment to prevent freezing.
What are the benefits of using the WIFI RDJ 100 FR/SET Thermostat compared to other traditional thermostats?
- The thermostat caters to the needs of older individuals who typically want a quick heating adjustment.
- The central knob assists with this.
- This model also allows connection where no boiler connection is prearranged.
- There’s no need to drill any holes to install the thermostat.
- The thermostat meets all modern accounting requirements.
Are there any precautions to take during installation to ensure the device isn’t exposed to humidity or water?
Yes, special care should be given to the receiver connected to the boiler. Ensure that:
- It isn’t installed near sinks or water sources.
- It isn’t positioned beneath the boiler (there’s always a possibility that the boiler might leak water in the future).
Remember, the receiver is connected to the high-voltage network
Useful Tips
Here are some useful tips for using your WIFI RDJ 100 FR / SET Thermostat:
- Always remember to set the operation selector (the one on the right) to RUN for the correct heating use.
- Be cautious when using Permanent Comfort for extended periods, as it could become costly in terms of consumption.
Battery Replacement:
Always check the battery charge; this thermostat operates using radio waves, so we suggest replacing the batteries at least once a year.
- Use only high-quality disposable batteries.
- Rechargeable batteries have low amperage and could cause issues with heating continuity.
Mounting and Installation
We always recommend consulting a specialized technician for the installation of the Siemens RDJ 100 FR / SET thermostat. This is because the receiver needs to be connected to the boiler both for the thermostat contact and for the electrical power from the grid.
The technician will use the Normally Open and Common contacts to activate the heating and will position the receiver in a location outside the boiler to ensure the device is not at risk of getting wet in the event of a leak
