This genuine Eberspacher Easystart 7-Day Timer (MPN: 221000341500) is designed for users of Eberspacher Airtronic air heaters and Hydronic S3 water heaters who seek convenient pre-heating and comfortable ambient temperatures. Its key benefit is enabling timed operation for a comfortable start, especially in cold weather. A crucial caveat is its specific compatibility requirement for Airtronic heaters, which must have the latest control unit identified by the H-Kit logo. The timer offers flexible 7-day scheduling, 12/24V compatibility, and a compact, surface-mountable design.

No, it is specifically compatible with Eberspacher Airtronic heaters that have the H-Kit logo on their dataplate, and Hydronic S3 water heaters. It is not compatible with older Airtronic models that lack the H-Kit designation.
This timer comes with a 12-month Eberspacher warranty.
Yes, the timer is designed to operate on both 12-volt and 24-volt vehicle electrical systems.
Connection requires wiring to the heater's control unit. For Airtronic heaters with the H-Kit logo, ensure the grey/red and brown/white cables are linked. Always refer to the detailed wiring diagram provided in the installation manual.
The timer itself does not include a remote temperature sensor. If remote temperature sensing is required for your Airtronic heater, you need to purchase the specific Easystart temp sensor (part number 221000342200) separately.
The timer has very compact dimensions: Width - 82 mm, Height - 37 mm, Depth - 12 mm.
Yes, the Easystart 7-Day Timer allows you to set unique heating schedules for each of the seven days, offering maximum flexibility.
Verify the 12V or 24V power supply connection to the timer. Check fuses in the vehicle/system. Ensure the connection to the heater control unit is secure.
Confirm the timer is correctly programmed with the correct time and day. Ensure the heater is within its operational parameters (e.g., sufficient fuel, battery voltage). For Airtronic, double-check the H-Kit compatibility and wiring (grey/red and brown/white cables linked).
Ensure the timer is set to the desired temperature. If using with an Airtronic heater and remote temperature sensing is needed, ensure the separate Easystart temp sensor is correctly installed and connected. Verify the heater's fan speed settings.
Check the power supply. If the issue persists, the unit may require servicing or replacement.
