Instead we were the first to achieve a revolutionary innovation in a pressure boosting autoclave system developing a patented, high performance, efficient, compact, easy and satisfactory to use for the installer and the end user. E.sybox has changed the way in which people use our most important resource, water. E.sybox is smart and versatile. E.sybox mini is the ideal solution to solve any water pressurisation issues in residential environments. E.sybox mini takes advantage of the most advanced DAB technologies, to ensure a consistent pressure based on actual demands, and therefore an optimisation of energy consumption.

The starting order is modified during use as necessary by the following 9.4.11 - Reserves and number of devices that participate in pumping two algorithms: The multipump system reads how many elements are connected in com- munication and calls this number N. • Reaching the maximum work time • Reaching the maximum inactivity time Then depending on the parameters NA and NC it decides how many and which devices must work at a certain time. 9.4.9 - Maximum work time Depending on the parameter ET (maximum work time), each device NA represents the number of devices that participate in pumping.

If the parameter ET (maximum work time) is set at 0, there is an exchange at each restart. See also the explanation of the parameters See 7.7.4 - ET: Exchange time. 7.7.1 - NA: Active devices; 7.7.2 NC: Simultaneous devices; 9.4.10 - Reaching the maximum inactivity time 7.7.3 IC: Configuration of the reserve. The multipump system has an anti-stagnation algorithm, the aim of which is to keep the pumps in perfect working order and to maintain the integrity of the pumped fluid. It works by allowing a rotation in the pumping order so as to make all the pumps supply at least one minute of flow every 23 hours. This happens whatever the device configuration (enabled or reserve). The exchange of priority requires that the device that has been stopped for 23 hours be given maximum priority in the starting order. This means that as soon as it is necessary to supply flow, it will be the first to start. The devices configured as reserve have precedence over the oth-106 ers. The algorithm ends its action when the device has supplied at least one minute of flow.

With the product DAB supplies an accessory tool that is useful for carry- ing out the operations contemplated on the system during installation and any special maintenance operations. The tool is housed in the technical compartment. It is composed of 3 keys: 1 - metal key with a hexagonal section (Fig.24 – 1); 2 - flat plastic key (Fig.24 – 2); 3 - cylindrical plastic key (Fig.17 – 3). Key “1” is in turn inserted in the end “D” of key “3”. At the first use you must separate the 2 plastic keys “2” and ”3”, which are supplied joined by a bridge (Fig.24 – A): break the bridge “A”, taking care to remove the cutting residue from the 2 keys so as not to leave any sharp bits that could cause injuries. 107

In in starting the pump: after a period of inactivity, perhaps with the system110 this case it is intentional, because it is preferable to damage the drained, the salts dissolved in the water could have settled and formed calcification between the moving part (motor shaft) and the fixed part of the pump, thus increasing the resistance on starting. In this case it may be sufficient to help the motor shaft by hand to detach itself from the calcifications. In this system the operation is possible because access to the motor shaft from outside is guaranteed and a groove is provided at the end of the shaft. Proceed as follows: 1- remove the motor shaft access cap as in Fig.29; 2- insert a straight tip screwdriver in the groove on the motor shaft and manoeuvre, turning in 2 directions; 3- if it turns freely, the system can be started; 4- if rotation is blocked it cannot be removed by hand, call the assistance service. 10.5 - Expansion Vessel See paragraph 1.2 for the operations to check and adjust the air pressure in the expansion vessel and to replace it if it is broken.
