Panasonic 140 Installation And Maintenance Manual page 35

1. Set all units in demand to open all the valves (load = 100%).
2. Set the water pressure setting to a high value (example: 8,0 bar)
3. Check that the output is in line with ECOi-W requirements.
4. Read the pressure value in the system (example: 3,5 bar).
5. Set the water pressure setting to the read value.
When the pressure setting is set, check that the system is operational in the following
conditions:
• when in partial load, the pressure is constant.
• when at zero load (all units off), check that the pump switches to stand-by and that no
water pressure alarm is triggered
13.4.9. Reduced mode
Reduced mode can have the following confi gurations:
• Decreased cool. setp
This function is only available if the unit is in cool mode. It can cool the building at night when electricity is less expensive.
• Eco
Heat and cool setpoints are respectively lowered and raised to reduce the unit's electrical consumption.
• Low noise
In cool mode, the condensation pressure setpoint is increased to reduce the noise generated by the ventilators.
• Eco + Low noise
The "reduced mode" mode activation can be triggered in the following ways:
• directly on the ECOi-W via the user interface
• communication network (Modbus/Bacnet/Cloud)
• external dry contact D2 if entry confi gured.
13.4.10. Limited capacity
Limited capacity is occasionally used to limit the electricity consumption of the ECOi-W to prevent exceeding the electric
power capacity of the installation site.
The "Limited capacity" mode activation can be triggered in the following ways:
• directly on the ECOi-W via the user interface
• communication network (Modbus/Bacnet/Cloud)
• external dry contact D2 if entry confi gured.
