3.7 Energy monitor
*3
End user can monitor accumulated*1 ‘Consumed electric 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
*3 Not available during Multiple outdoor unit control.
Refer to “7.2 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: The method 1 should be used as a guide. If a certain accuracy is required, the method 2 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 locally supplied 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 “7.2
Main remote controller”)

*1 Be sure to change the setting corresponding to the specification of locally supplied auxiliaries such as electric heater and pump.
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 “7.2 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 “4.5 Connecting inputs/outputs” for more information on connectable electric energy meter and heat meter.

* If there is a bypass circuit, above table means minimum water amount in
case of bypass.
** Please refer to 2009/125/EC: Energy-related Products Directive and Regu-
lation (EU) No 813/2013 to confirm your climate zone.
Case 1. No division between primary and secondary circuit
• Please ensure the required water amount according to the table 3.6.1 by
water pipe and radiator or underfloor heating.
Case 2. Separate primary and secondary circuit
• If the interlock operation of primary and secondary pump is not available,please
ensure required additional water in only primary circuit according to the table
3.6.1.
• If the interlock operation of primary and secondary pump is available, please
ensure total water amount of primary and secondary circuit according to the
table 3.6.1.
In case of the shortage of required water amount, please install buffer tank.
