PC-ARFH1E1(02/03) FUNCTIONALITIES

Emergency Operation
Mode:
Selection of the emergency operation mode:
• Manual: Emergency operation is active
when is manually enabled (by DSW4 pin 4
ON). The emergency mode uses the heater
(space heating or DHW) to provide the
required heating.
• Automatic: Emergency mode operates
when there is an event of outdoor unit failure
and Demand ON of space heating (enabled)
or DHW (enabled).
1.8.2.10 Inputs, Outputs and Sensors configuration
Auxiliary sensors:
There are 7 available auxiliary sensors to
set.

List of available inputs:
• Disabled
• Demand ON/OFF (by default in input 1): Consider both Circuit 1 and Circuit 2 in Demand ON when the signal is ON.
• Demand ON/OFF C1: Consider Circuit 1 in Demand ON when the signal is ON.
• Demand ON/OFF C2: Consider Circuit 2 in Demand ON when the signal is ON.
• Power Meter 2: To count any pulse received from the power meter 2 and sent to central control energy consumption calculation.
• ECO C1 + C2: Switch both Circuit 1 and Circuit 2 to ECO mode when input is closed.
ECO C1 (by default in input 2, if there is circuit 1 in the installation): Switch Circuit 1 to ECO mode when input is closed.
•
• ECO C2: Switch Circuit 2 to ECO mode when input is closed.
• Forced Off: Forbid DHW, space heating and space cooling.
Smart Act / SG1 (Fixed in input 5 if smart action is enabled): To active Smart Function.
•
• Swimming Pool (Fixed in input 3 if swimming pool is enabled): Consider Swimming pool in Demand ON when the signal is ON.
• Solar (Fixed in input 4 if solar is enabled): To let YUTAKI know that external Solar management system is ready to provide Solar
energy.
• Operation: To switch between space cooling and space heating.
• DHW Boost (Fixed in input 6 if is DHW Boost is enabled): If it is set to open (NC), boost signal ON if circuit is open. If it is set to
close (NO), boost signal ON if circuit is closed.
• Power Meter 1 (Fixed in input 7 if Power Meter 1 is enabled): To count any pulse received from the power meter 1 and sent to
central control energy consumption calculation.
• Forced Heating: Force mode heating when input is closed
• Forced Cooling: Force mode cooling when input is closed.
• SG2: To active the different estates of Sm Grid Ready.
