1. General description
End user can monitor accumulated (*

* - DHW operation
2
- Space heating
- Space cooling
Refer to the menu tree in "9-3. Main Settings Menu" for how to check the energy, and "6-16. 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.
(1) Calculation internally 【Method 1】
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 unit model and specs of additional pump(s) supplied locally. (Refer to the menu tree
in "9-3. Main Settings Menu")

* 1 Change setting to 3 kW 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 the menu tree in "9-3. Main Settings Menu".
(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 inputs] in "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 12 V DC 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 "9-3. Main Settings Menu".)
2. Settings using the main remote controller
In this menu, all parameters required to record the consumed electrical energy and the
delivered heat energy which is displayed on the main remote controller can be set. The
parameters are an electric heater capacity, supply power of water pump and heat
meter pulse.
Follow the procedure described in General Operation for the set up operation.
For Pump 1, *** can be also set besides this setting.
In the case *** is selected, the system acknowledges "factory fitted pump" is selected.
