Gone are the days when two pumps were taken to the basement for safety, just in case the other one breaks. A pump that has rusted for 10 years will not help you to warm a cold house in the event of an accident. A modern heating unit reports a deviation from the required temperature and your maintenance company can react before the temperature in the rooms starts to fall.
The reliability of the error message is ensured by the use of standard communication protocols, combined with a suitable data transmission channel. Today, heat supply units with guaranteed supply are history in Estonia. However, if the power goes out, the necessary messages will reach the customer, as Siemens will check for itself whether the unit is currently operational and you will be notified of the interruption immediately.
