It corresponds to the temperature change (ΔT) of the detected room temperature (T) per fixed time.
To determine the overshoot value and duration (K), and add the set temperature (T ₀ ) to the determined overshoot value.
Calculated sensation set temperature (T ₁ )
The controller (4) is configured so that the detected room temperature (T) is equal to the sensed temperature.
Degree (T ₁ ), the detection room temperature (T) is further
Maintain the set temperature (T ₁ ) for the duration (K).
Experience control to control the heating capacity of the heating source (11)
A warm air heater (B), which is performed at an early stage of a heating operation.
