Hitachi YUTAKI RWM-2R1E - Setup of Inputs, Outputs and Sensors


Emergency Operation
Space Heating:
Enable or disable emergency operation
for space heating.
Only available in case “Heating source”
on “10.6.2.6 Complementary Heating
conguration” contains “Electrical
heater option”
DHW:
Enable or disable emergency operation
for DHW. Only available when electrical
heater for DHW is enabled (by DSW).
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
Outputs:
There are 8 available outputs to set. There
are conditions of setting depending on the
installation.
Auxiliary sensors:
There are 7 available auxiliary sensors to set.
Inputs:
The system allows to set 7 inputs depending
on the operations and preferences of the
installation

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.
