Overall, the Danfoss 103 Timer is a versatile and reliable device that provides a range of useful features for controlling your electric heating system.
How to operate
Operating the Danfoss 103 Timer is relatively simple, and can be done using the following steps:
- Set the clock: Turn the dial to set the current time. The clock operates on a 24-hour basis, so make sure you set it correctly.
- Set the on/off times: Turn the timer dial to the desired on time for your heating system. Press the red switch down to set the time. Repeat this process for the desired off time.
- Set the temperature: Turn the temperature dial to the desired temperature for your heating system. The temperature range is from 5°C to 30°C. This may or may not be an option on the unit.
- Boost function: To use the boost function, press the grey button on the front of the timer. This will turn your heating system on for one hour at the current temperature setting.
- Holiday mode: To use the holiday mode, turn the temperature dial to the desired temperature for your heating system while you are away. Press the red switch down for five seconds to enter holiday mode. The temperature will automatically return to its previous setting when the holiday mode ends.
- Override function: To override the current settings, turn the timer dial to the desired on or off time. The heating system will switch on or off according to the new settings until the next programmed time.
- Battery replacement: If the battery symbol appears on the display, it is time to replace the battery. The battery compartment is located on the bottom of the timer. Replace the battery with a new one.
That’s it! With these simple steps, you should be able to operate your Danfoss 103 Timer with ease.
Technical information
| SPECIFICATION | |
|---|---|
| Brand | Danfoss |
| Central heating control type | Timer |
| Heating system compatibility | Designed to work with a range of different heating and hot water systems, but it’s important to make sure that it is compatible with your specific system before purchasing. |
| Control operation | – Allows users to set heating and hot water schedules with a 24-hour time clock. – Has a clear LCD display that shows the current time, date, and status of the timer. – Can be set to “holiday” mode, which turns off the heating and hot water systems when the user is away from home. |
| Temperature range | 0°C to 40°C |
| Display type | Clear LCD |
| Hertz (Hz) | Designed to operate on a frequency of 50Hz. This is the standard frequency used for power distribution in many parts of the world, including Europe, Asia, Africa, and Australia. |
| Switch rating | 2(1)A 250V AC (resistive load) |
| Max. load (Inductive) | 1 amp at 230V AC The Danfoss 103 timer has a switch rating of 2(1)A 250V AC for resistive loads. However, for inductive loads such as those found in some types of heating and cooling equipment, the maximum load that the Danfoss 103 timer can handle may be lower. According to the Danfoss 103 timer datasheet, the maximum inductive load for the device is 1A at 230V AC. It’s important to note that this rating is for inductive loads with a power factor of 0.6 or higher. Loads with a lower power factor may require additional derating, meaning that the maximum load that the timer can handle would be even lower. |
| Max. load (Resistive) | 2 amps at 250 volts AC The Danfoss 103 timer has a switch rating of 2(1)A 250V AC for resistive loads. This means that the maximum load the timer can handle for purely resistive loads, such as incandescent lights or electric heaters, is 2 amps at 250 volts AC. It’s important to note that the maximum load capacity of the Danfoss 103 timer for resistive loads should not be exceeded, as doing so could cause the timer to malfunction or fail. Additionally, the maximum load capacity may be lower for inductive loads or loads with a low power factor, as I mentioned in my previous answer. |
| Power consumption | Approximately 2W when the backlight is on, and 1W when the backlight is off. |
| Dimensions | 84mm x 84mm x 32mm (H x W x D) |
| Battery backup | Rechargeable NiMH battery |
| Programmer Voltage | 230V AC. This is the standard voltage used for power distribution in many parts of the world, including Europe, Asia, Africa, and Australia. |
| Smart compatibility | No. |
| Terminal capacity | 2 Amps. The total current drawn by all the devices connected to the thermostat terminals should not exceed 2 Amps. The Danfoss 103 timer has four terminal connections labeled N (neutral), L (live), 1, and 2. The terminal capacity for each connection is as follows: N (neutral): 2 x 2.5mm² or 1 x 4mm² L (live): 2 x 2.5mm² or 1 x 4mm² 1 and 2: 2 x 1.5mm² or 1 x 2.5mm² This means that each terminal can accommodate either two wires with a maximum size of 2.5mm² or a single wire with a maximum size of 4mm², depending on the terminal. The terminal capacity is important to consider when wiring the Danfoss 103 timer to ensure that the wires are properly connected and that the maximum current capacity of the timer is not exceeded. It’s important to note that the maximum current capacity of the Danfoss 103 timer is 2 amps, and the total load on the timer should not exceed this rating. If you have any questions or concerns about the terminal capacity or wiring of the timer, it’s recommended that you consult with a qualified electrician or heating technician. |
