Maximum / Minimum temperature for
heating and cooling:
Configure for Circuit 1/2:
•
Heating maximum temperature
• Heating minimum temperature
•
Cooling maximum temperature
• Cooling minimum temperature
Air Eco Offset for Circuit 1-2:
Configure the offset air temperature for the
ECO mode.
Current air temperature setting is reduced
by the indicated parameter (from 1 to 10 ºC)
Room Temperature Demand OFF:
Offset value between setting temperature and
thermostat temperature to switch the system
to Demand OFF; this parameter refers to a
positive difference in heating operation and a
negative difference in cooling operation.
Compensation factors for Heating / Cooling
The temperature of the water supplied by the YUTAKI unit to the circuits is determined by means of OTC (See
).
This control determines water temperature according to the outdoor temperature. The higher the outdoor temperature, the lower
the building demand is, and in consequence the temperature of the water supplied to the circuits is lower. Conversely, the thermal
demand of the building rises in the case of low outdoor temperature, and therefore the temperature of the supplied water becomes
higher.
The room temperature compensation control allows to modify the water temperature determined by OTC control according to the
setting room temperature and the actual room temperature.
In the case of heating, if the difference between room temperature and setting temperature is large, then water temperature is
increased by the YUTAKI unit in order to achieve the desired room temperature in a faster way, thus compensating the thermal
difference between setting temperature and actual temperature.
In this manner, given two identical 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 difference between setting temperature and actual temperature, the YUTAKI unit will
increase the temperature of the pumped water in order to ensure a similar heating up time until reaching the setting temperature.
Compensation has no effect if Compensation factor is 0 or when OTC is Fix, and water temperature is determined according to OTC
The more the factor is increased, the more is water temperature increased by the YUTAKI unit according to the difference between
setting temperature and the current temperature.
Maximum compensation factor heat + and -
: Maximum difference between room temperature and setting temperature. In case
that the difference between room temperature and setting temperature is higher than this value, the YUTAKI unit takes the selected
value as the maximum.
