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 "9-1. Main remote controller" on the paper-based manual for how to check the energy, and "6-6. DIP switch functions" on the paper-based manual for the
details on DIP-SW setting. Either one of the following two 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.

(1) Calculation internally
Electricity consumption is calculated internally based on the energy consumption of outdoor unit, electric heater, water pump(s) and other auxiliaries.
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 model name and specs of additional pump(s) supplied locally. (Refer to the menu tree
in "9-4. Main Settings Menu")
Change setting to 3kW when connecting optional immersion heater
*1
"***" displayed in the energy monitor setting mode means the factory fitted pump is connected as Pump 1 so that the input is automatically calculated.
*2
When the cylinder unit is connected with a PUHZ-FRP or PUMY models, electricity consumption is not calculated internally. To display the electricity consumption,
*3
conduct the 2nd method.
When additional pumps supplied locally are connected as Pump2/3, change setting according to specs of the pumps.
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 "5.7 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] in section "6. WIRING DIAGRAM" for more information on connectable electric energy meter and heat meter.
● Connectable electric energy meter and heat meter
▪ Voltage free contact for 12VDC detection by FTC (TBI.3 1, 3 and 5 pin have a positive voltage.)
Pulse meter type
▪ Minimum ON time: 40 ms
Pulse duration
Minimum OFF time: 100 ms
▪
0.1 pulse/kWh
Possible unit of pulse
100 pulse/kWh
Those values can be set by the main remote controller. (Refer to the menu tree in "9-4. Main Settings Menu".)
