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 se

Refer to the menu tree in “9-3. Main Settings Menu” for how to check the energy, and "6-5. DIP switch setting" for the details on DIP-SW setting.
Either one of the following 2 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 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
Default setting is used for E*SC(D)/EHPX models. Please change setting according to the table above.
*
2
Change setting to 3 kW when connecting optional immersion heater “PAC-IH03V2-E”.
*
3
Please change setting according to the table below.
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 (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
