PC-ARFH1E FUNCTIONALITIES
In this manner, given two idencal rooms, the YUTAKI unit determines the same room temperature
according to OTC control. On the other hand, for a room in which there is a wider dierence
between seng temperature and actual temperature, the YUTAKI unit will increase the
temperature of the pumped water in order to ensure a similar heang up me unl reaching the
seng temperature.
Compensaon has no eect if Compensaon factor is 0 or when OTC is Fix, and water temperature
is determined according to OTC in chapter “Water calculaon mode” in such case.
The more the factor is increased, the more is water temperature increased by the YUTAKI unit
according to the dierence between seng temperature and the current temperature.
Maximum compensaon factor heat + and - : Maximum dierence between room temperature
and seng temperature. In case that the dierence between room temperature and seng
temperature is higher than this value, the YUTAKI unit takes the selected value as the maximum.
