PC-ARFH1E FUNCTIONALITIES
1.8.2.1 General opons conguraon
Room Thermostats:
Congure 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)
• Compensaon factors (See Compensaon factors secon below)
• Room Temperature Demand OFF: Oset value between seng temperature and thermostat
temperature to switch the system to Demand OFF; this parameter refers to a posive dierence in
heang operaon and a negave dierence in cooling operaon.
• Check RT Address: validaon procedure of the wireless thermostats conguraon

Air Eco Oset for Circuit 1-2:
Congure the oset air temperature
for the ECO mode.
Current air temperature seng is
reduced by the indicated parameter
(from 1 to 10 ºC)
Central operaon:
• Control type selecon: Local, air,
water or full. Only available when
Cascade Mode is disabled.
• Enable or disable Cascade Mode,
when the system is connected to a
CASCADE CONTROLLER.
Maximum Seng T. (Air):
• Circuit 1
• Circuit 2
◆ Compensaon factors for Heang / Cooling
The temperature of the water supplied by the YUTAKI unit to the circuits is determined by means
of OTC (See “Water calculaon mode”).
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 compensaon control allows to modify the water temperature determined
by OTC control according to the seng room temperature and the actual room temperature.
In the case of heang, if the dierence between room temperature and seng 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 compensang the thermal dierence between seng
temperature and actual temperature.
