 What is a “forecast” function?
 Adaptive, self-learning, forecast, optimum start/stop
 Response time in the room is measured, stored,
 With and without heating, constantly and every day
 Used as parameter in the algorithm to calculate when
to start/stop heating
 To meet to the demand for comfort entered in the
timer and temperature settings (customer
expectations)
 Thus using the least amount of energy

28. Forecast Function
 Optimum end (fade-out)
 Why?
 To avoid turning the relay on just before the comfort
period ends and the economy period begins
 How?
 Defined by offsetting the comfort setpoint by using
the intelligence/adaptiveness
 when temperature is lowering less than 0,3-0,5°C
