Schedule timer
Scheduled timer can be set in two ways, for example; one for summer and the other for winter. (Refer to as "Schedule 1" and
"Schedule 2" respectively.) Once the term (months) for the Schedule 1 is specifi ed, rest of the term will be specifi ed as Schedule 2.
In each Schedule, an operational pattern of modes (Heating / DHW) can be set.
If no operational pattern is set for Schedule2, only the pattern for Schedule 1 will be valid. If Schedule 2 is set to full-year (i.e.
March to Feb.), only the operational pattern for Schedule 2 will be valid.
Follow the procedure described in General Operation (Page 24) for the set up operation.
Setting the schedule timer
The preview screen allows you to view the current settings. In 2-zone heating
operation, press F1 to switch between Zone1 and Zone2. Days of the week are
displayed across the top of the screen. Where day appears underlined the settings
are the same for all those days underlined.
Hours of the day and night are represented as a bar across the main part of the
screen.
Where the bar is solid black, space heating/DHW (whichever is selected) is allowed.
When scheduling heating, button F1 changes the scheduled variable between time
and temperature. This enables a lower temperature to be set for a number of hours e.g.
a lower temperature may be required at night when the occupants are sleeping.
• The schedule timer for space heating and DHW are set in the same way. However for DHW only time can be used as
scheduling variable.
• A small rubbish bin character is also displayed choosing this icon will delete the last unsaved action.
• It is necessary to use the SAVE function F4 button to save settings. CONFIRM does not act as SAVE for this menu.

System Set Up
Service Menu
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.
The service menu is navigated using the F1 and F2 buttons
to scroll through the functions. The menu is split across
several screens and is comprised of the following functions;
1. Manual operation
2. Function settings
3. Thermistor adjustment
4. Auxiliary settings
5. Heat source setting
6. Pump speed
7. Operation settings
8. Energy monitor settings
9. Running information
10. Thermistor reading
11. Summary of settings
12. Error history
13. Password protection
14. Manual reset
15. SD card
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 controller will display a reminder
message prompting the installer to stop operation before continuing. By selecting "Yes" the unit will cease operation.
<Manual operation>
During the fi lling of the system the water circulation pump and 3-way valve can
be manually overridden using manual operation mode.
When manual operation is selected a small timer icon appears in the screen.
The function selected will only remain in manual operation for a maximum of
2 hours. This is to prevent accidental permanent override of the FTC.
►Example
Pressing F3 /D button will switch manual operation mode ON for the main 3-way
valve. When fi lling of the thermal store tank is complete the installer should
access this menu again and press F3 /D to deactivate manual operation of the
part. Alternatively after 2 hours manual operation mode will no longer be active
and FTC will resume control of the part.
<Auxiliary settings>
This function is used to set the parameters for any auxiliary parts
used in the system
