Technical Information
Energy monitor
End user can monitor accumulated*1 'Consumed electrical energy' and 'Delivered heat energy' in each operation mode*2 on the main remote controller.
*1 Monthly and Year to date
*2 - DHW operation
- Space heating
- Space cooling
Refer to "5.10 Main remote controller" for how to check the energy, and "5.1 DIP switch functions" for the details on DIP-SW setting.
Either one of the following two method is used for monitoring.
Note: Method 1 should be used as a guide. If a certain accuracy is required, the 2nd method should be used.
1. Calculation internally
Electricity consumption is calculated internally based on the energy consumption of outdoor unit, electric heater, water pump(s) and other auxiliaries. (*3)
Delivered heat is calculated internally by multiplying delta T (Flow and Return temp.) and flow rate measured by the factory fitted sensors.
Set the electric heater capacity and water pump(s) input according to indoor unit model and specs of additional pump(s) supplied locally. (Refer to the menu tree in "5.10
Main remote controller")

*1 Change setting to 3kW when connecting optional immersion heater "PAC-IH03V2-E".
*2 "***" displayed in the energy monitor setting mode means the factory fitted pump is connected as Pump 1 so that the input is automatically calculated.
*3 When the hydrobox is connected with a PUHZ-FRP or PUMY models, electricity consumption is not calculated internally. To display the electricity consumption, conduct
the 2nd method.
When anti-freeze solution (propylene glycol) is used for primary water circuit, set the delivered energy adjustment if necessary.
For further detail of above, refer to "5.10 Main remote controller".
2. Actual measurement by external meter (locally supplied)
FTC has external input terminals for 2 'Electric energy meters' and a 'Heat meter'.
If two 'Electric energy meters' are connected, the 2 recorded values will be combined at the FTC and shown on the main remote controller.
(e.g. Meter 1 for H/P power line, Meter 2 for heater power line)
Refer to the [Signal inputs] section in "5.2 Connecting inputs/outputs" for more information on connectable electric energy meter and heat meter.
