How does it work?
The ista T‑Logger measures room temperature with high precision and sends data directly to the administrator via radio.
When a resident reports a temperature problem, the administrator can immediately check the measurements and see if the temperature is within the expected range.
The result is fewer unnecessary interventions, higher resident satisfaction, and consistent energy consumption across the building, with lower costs, better efficiency, and increased comfort for all parties.
