<Energy monitor settings>
1. General description
End user can monitor accumulated (*
1
) consumption and production 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 the menu tree in “9-1. Main remote controller” for how to check the energy, and “6-5. DIP switch functions” for the details on DIP-SW setting.
Either one of the following 2 methods 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.
Method 1. Calculation internally Method
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 temperature) and flow rate measured by the factory fitted sensors.
Set the electric heater capacity and water pump(s) input according to indoor model name and specs of additional pump(s) supplied locally. (Refer to the menu tree
in “9-1. Main remote controller”)

*3 When the hydrobox is connected with a PXZ or PUMY models, electricity consumption is not calculated internally. To display the electricity consumption, use the
2nd method.
*4 "***" displayed in the energy monitor setting mode means the factory tted pump is connected as Pump 1 so that the input is automatically calculated.
When anti-freeze solution (propylene glycol) is used for primary water circuit, set the delivered energy adjustment if necessary.
Should you need more details, refer to the menu tree in “9. Controls”.
Method 2. Actual measurement by external meter Method 2 (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 input" in “6. WIRING DIAGRAM” for more information on connectable electric energy meter and heat meter.
● Connectable electric energy meter and heat meter
▪ Pulse meter type
Voltage free contact for 12 VDC detection by FTC (TBI.3 1, 3 and 5 pin have a positive voltage.)
▪ Pulse duration
Minimum ON time: 40 ms
Minimum OFF time: 100 ms
▪ Possible unit of pulse
0.1 pulse/kWh 1 pulse/kWh 10 pulse/kWh
100 pulse/kWh 1000 pulse/kWh
Those values can be set by the main remote controller. (Refer to the menu tree in "9-3. Main Settings Menu".)
