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.
1- INTRODUCTION First of all, thank you for choosing E.C.A. E.C.A. ARCEUS electric combi boilers are intended for meeting central heating and hot domestic water requirement in an efficient, safe, and comfortable manner. ARCEUS electric combi boilers can operate on 220-240 VAC (6/9/12/15 kW) and 380-415 VAC (6/9/12/15/18/24/27 kW) power. MT model: It is intended for both central heating and hot domestic water requirement.
SAFETY RULES AND WARNINGS 4.1- Safety Rules The power line to which the device is connected must have cross-sectional dimensions as specified in the manual and grounded. For three-phase operating devices, a three-phase power supply must be available at the installation location. Leakage current protection relay must be connected before the device input.
CAUTION: If the device is used incorrectly and inappropriately, it may pose a life- threatening risk and may cause material damage to the product and its surroundings. CAUTION: This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.

10.3.5- Domestic Hot Water (DHW) Eco Mode: At the times that hot water demand is not expected (e.g. holidays etc.) or more economic use is preferred, ECO mode prevents the water in the exchanger to be heated and provides a more economic use of the device. When the ECO Mode is active “EC”...
10.4.4- Maintenance Reminder Function: After the time period that the device stays connected to the power upply reaches 8760 hours (1 year), the customer is informed that the annual maintenance time has come by flashing “ASE” characters and steady alarm icon on the screen.
This error is displayed if the solar boiler tank temperature sensor is Solar Boiler Tank short or open circuit, or damaged. Domestic water and central Temperature Sensor heating demands are stopped. When this error is cleared, normal Error operation begins. This error is displayed if the solar panel temperature sensor Solar Panel Temperature (PT1000) is short or open circuit, or damaged.
12.3- Cleaning of Combi Boiler Keep the outer casing of the combi boiler clean by wiping it with a soft damp cloth. Do not use strong, abrasive cleaning agents. During and after the warranty period of the combi boiler, performing maintenance regularly once a year before the winter season ensures safe use and prolongs the life of the device.
