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).

10.6.2.9 Setup of inputs, outputs and sensors

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.
• 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.
• 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.
