Initial Start-Up, Operation And Shut Down - E.C.A. ARCEUS EK 12 MT User And Installation Manual For this unit, what do you do if the unit is stuck on the AP cycle? Meaning it just keeps running the AP cycle and makes a noise every 20 seconds and runs through the 20 second cycle again and again? Or in other words, how long after a power outage should it take to complete the AP cycle? Thanks, Jim

If the E.C.A. ARCEUS EK 12 MT unit is stuck on the AP (anti-blocking) cycle and continues to run the cycle repeatedly, check if there is a heat demand. The anti-blocking function is interrupted if heat demand occurs, and the valve returns to normal working position. If the device remains stuck without heat demand, it may require inspection or service.

The AP cycle (anti-blocking function) activates every 24 hours and runs for 10 seconds. After a power outage, the cycle should not take more than 10 seconds to complete.
