Answer: The reason the thermostat turns on frequently during the first few days after installation is related to the TPI heating algorithm.
It requires an adaptation period of 4 to 7 days, during which it calibrates based on the house insulation and other parameters.
During this time, the boiler will turn on more often and for varying durations—shorter or longer—before stabilizing. This way, the thermostat calculates how long the boiler needs to run during each cycle to maintain the temperature as constant and close as possible to the user-set value
