When the voltage is disconnected, the boiler resets and detects a flow error because the ez are closed when no one is heating at this point. That is why I need something to support so that the stove electronics does not reset when the electricity is turned off for 30 seconds at night.
From what you write, it can be concluded that you have overdone this installation, the boilers are built in such a way that a power interruption of 30 seconds is not a problem and after restoring the power supply, each efficient boiler should start normal operation. The problem, however, may be very short interruptions that generate disturbing pulses.
I have been using two installations with gas boilers for about 20 years and so far I have had no major problems with power outages, and the installations are quite complicated.
A power outage of up to several hours is no problem. On the other hand, buying a UPS Ever ECO cds700 Pro is a mistake, even with a 40 Ah battery connected to the outside, there is no need to count on any significant effects because the UPS will turn on when there is no power in the network, regardless of whether there is a demand for heat or not, and when it will be needed that the battery is discharged. The only logical solution is a system based on a controller that will turn on the UPS only in case of heat demand and reset the boiler if necessary, i.e. an error caused by disturbances and the central heating installation must also be well thought out in terms of energy demand for emergency power supply.
It is all to be done, but it is not cheap.
