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 Thermostats:
Configure the wired or wireless room thermostats:
• Thermostat 1: None, wired or wireless
• Wireless Binding ID for Thermostat 1: (1 or 2)
• Thermostat 2: None, wired or wireless
• Wireless Binding ID for Thermostat 2: (1 or 2)
• Compensation factors (See Compensation factors section below)
• 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.
• Check RT Address: validation procedure of the wireless thermostats configuration
◆ 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
"Water calculation
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.
