The service menu provides functions for use by installer or service engineer. It is NOT intended the home owner alters settings within this menu. It is for this reason
password protection is required to prevent unauthorised access to the service settings.
The factory default password is "0000".
Follow the procedure described in General Operation for the set up operation.
<Manual operation>
During the filling of the system the primary circuit circulation pump can be manually overridden using
manual operation mode.
When manual operation is selected a small timer icon appears in the screen. When selected, this
function will only remain in manual operation for a maximum of 2 hours. This is to prevent accidental
permanent override of the FTC.
Many functions can not be set whilst the indoor unit is running. The installer should turn off the unit before trying to set these functions. If the installer attempts to change
the settings whilst the unit is running the main remote controller will display a reminder message prompting the installer to stop operation before continuing. By selecting
“Yes” the unit will cease operation.
Manual operation and heat source setting can not be selected if the system is running.
A screen will be displayed asking the installer to stop the system before these modes
can be activated.

Function/ Description
Economy settings for
pump
Water pump stops automatically a specified period of time from when operation is
finished.
Delay
Time before pump switches off*1
Electric heater
(Heating)
To select "WITH booster heater (ON)" or "WITHOUT booster heater (OFF)" in
Heating mode.
Delay
The minimum time required for the booster heater to turn ON after Heating mode
has started.
Flow
sensor *2
Minimum
The minimum flow rate to be detected at flow sensor.
Maximum
The maximum flow rate to be detected at flow sensor.
*1. Decreasing "time before pump switched off" may increase the duration of stand-by in heating mode.
*2. Do not change the setting since it is set according to the specification of flow sensor attached to the Hydro
box.
<Heat source setting>
The default heat source setting is heat pump and all electric heaters present in the system to be operational.
This is referred to as standard operation on the menu.
<Operation settings>
Heating operation
This function allows operational setting of flow temperature range from the Ecodan and also the time interval at which the FTC collects and processes data for the auto
adaptation mode.

At Fast mode, target outlet water temperature is set higher than the one set
at normal mode. This reduces the time to reach the target room temperature
when the room temperature is relatively low.*

<Table 5.6.1> Heating operation(Room temp.control table)
Note:
1. The minimum flow temperature that prohibits heat pump operation is 20ºC.
2. The maximum flow temperature that allows heat pump operation equals to the maximum temperature set in the Flow temp. range menu.
* Fast mode is not efficient and will increase running cost when compared to normal mode.
