◆ List of available inputs:
• Deactivated
• 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.
• Drain pump: When the contact is opened for 30 seconds operation is forbidden and Alarm 85
is shown. The purpose of this input is to link with the Drain pump's float switch to avoid water
overflow in case of drain pump failure
