ELECTRICAL AND CONTROL SETTINGS
?
N O T E
• If wireless intelligent thermostat is selected, optional ON/OFF thermostat has no effect.
• Set the configuration in the user's control. See chapter
• In case of setting an installation with 2 circuits (Circuit 1 and Circuit 2) and a different Demand ON/OFF is used for each of them, please refer to
"7.4.2.5 Input terminals (Default input functions)"
• For YUTAKI M R32 models: Auxiliary power supply is available for thermostats and central devices (28 and 29 terminals of TB2).

ECO (Default for input 2)
When enabled at Unit controller, both for circuit 1 and circuit 2, also for heating and cooling, this input switches the indoor unit into
an ECO mode by adjusting its settings only when input is closed.
The input can come from a push button, a thermostat or any other external device with that purpose.

Swimming pool (Default for input 3)
When it is necessary to control the temperature of the swimming pool water, a connection between the heat pump and the
corresponding sensor must be done on terminals 16 and 17 at the Terminal board (input 4).

Solar (Default for input 4)
This input comes from a solar panel sensor. The solar combination by input demand allows HSW to be heated by solar system when
there is enough solar energy available. The connection of this input signal has to be done between terminals 16 and 18 at TB2.

Smart tariff (Default for input 5)
This function can be used to block or limit the heat pump. It allows an external Smart switch device to switch off or limit the heat
pump during a period of peak electricity demand. Terminals 16 and 19 of the TB2.
