Hello. Can anyone here please advise if they have ever installed or have any experience of, the Hormann Promatic AKKU operating system? Thank you, Pete.
How can we help you with the AKKU system Pete and do you have any specific questions about the system ?
How can we help you with the AKKU system Pete and do you have any specific questions about the system ? Hello and thanks for your response. Was hoping to find someone who is using one of these systems, in order to gain some feedback. Specific questions are :- 1, What voltage is the power pack? 2, Asumming a brand new Hormann retractable door, how many seconds from closed to fully open and from open to down and locked? Any input from actual hands-on experience would be much appreciated. Thank you, Pete.
Hi Pete, We have used the Promatic Akku only once and can confirm that the voltage is 24V DC, with regards to opening/closing speed, this will depend on the weight of the door and how the Promatic operator has been setup (ie soft start/soft stop on or off), but Hormann claim an operating speed of 13cm per second, this will obviously change according to the level of charge. I hope that this helps.
Many thanks for your reply. The system runs on 24v at 10amps according to Hormann themselves. They state that the system operates at 13cm per second, their website also states that their mains powered units run at 14cm per second. I am assuming that these are " no load " speeds and therefore, will bear little relationship to real world conditions. It is for this reason that I hoped to find someone who is already using the AKKU system. Many thanks again, Pete.
Hi Peter, This is why I replied above that it does depend on the door you are operating on the system, as this will alter the speed/load at which it operates. Without being able to try it first, it is hard to say with any conviction what these will be. Only Hormann themselves would probably be able to answer that question, as they will have bench tested the unit in development and would hope that they tested it against different loads etc. Unfortunately though, in the real world with real garage doors and not in a test centre, things work differently, including the temperature at which the battery pack is to be stored, in winter the life will be less than in summer. There are so many variables.
