<Energy monitor settings>
1. General description
(1) Calculation internally
(2) Actual measurement by external meter (locally supplied)
Ɣ
Connectable electric energy meter and heat meter
ƒ
Pulse meter type
Voltage free contact for 12VDC detection by FTC (TBI.1 5, 7 and 9 pin have a positive voltage.)
ƒ
Pulse duration
Minimum ON time: 40ms
Minimum OFF time: 100ms
ƒ
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".)
Note: Consumed electric energy of pump A is automatically calculated by the system.
*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.
When anti-freeze solution (propylene glycol) is used for primary water circuit, set the produced energy adjustment if necessary.
For further detail of above, refer to “9-3. Main Settings Menu”.
End user can monitor accumulated*1 ‘Consumed electrical energy’ and ‘Delivered energy’ in each operation mode*2 on the main controller.
*1 Monthly and Year to date
*2 - DHW operation
- Space heating
Refer to “9-3. Main Settings Menu” for how to check the energy, and “6-2. DIP switch Functions” for the details on DIP-SW setting.
Either one of the following two method is used for monitoring.
Note: The method 1 should be used as a guide. If greater accuracy is required, then method 2 should be used.
Electricity consumption is calculated internally based on the energy consumption of outdoor unit, electric booster heater, pump1 and other auxiliaries.
Produced heat is calculated internally by multiplying delta T (Flow and Return temp.) and flow rate measured by the factory fitted sensors.
Set the electric booster heater capacity and water pump(s) input according to indoor unit model. (Refer to the menu tree in “9-3. Main Settings Menu”)

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 controller.
(e.g. Meter 1 for main power line, Meter 2 for booster heater power line)
Refer to the [Signal inputs] section in “6. WIRING DIAGRAM” for more information on connectable electric energy meter and heat meter.
