7. Remote controller operation
Setting the remote controller
After the power has been connected to the outdoor unit and FTC2BR unit, the initial system settings can be entered
via the remote controller.
1. Check all breakers and other safety devices are correctly installed and turn on power to the system.
2. When the remote controller switched on for the first time, the screen automatically goes to Initial settings menu, lan-
guage setting screen and date/time setting screen in order.
3. Remote controller will automatically start up. Wait approximately 6 min whilst the control menus load.
4. When the controller is ready a blank screen with a line running across the top will be displayed.
5. Press button E (Power) (refer to page 23) to turn on the system. Before turning on the system, perform initial
settings as instructed below.
Main menu
The main menu can be accessed by pressing the MENU button. To reduce the risk of untrained end users altering the
settings accidentally there are two access levels to the settings; and the service section menu is password protected.
User Level – Short press
If the MENU button is pressed once for a short time the settings will be displayed but without the edit function. This will
enable the user to view current settings but NOT change the parameters.
Installer Level – Long press
If the MENU button is pressed down for 3 secs the main settings will be displayed with all functionality available.
The following items can be viewed and/or edited (dependent on access level).
• Water temp. setting (Installer level)
• Compensation curve
• Initial settings
• Service (Password protected)
Use the F2 and F3 buttons to move between the icons. The highlighted icon will appear as a larger version in the cen-
tre of the screen. Press CONFIRM to select and edit the highlighted mode.
Initial settings
From the Initial settings menu the installer can set the following.
• Date/Time
• Language
• ºC/ºF
• Temp. display
• Contact number
• Time display
• Main/Sub
1. Use buttons F1 and F2 to move scroll through the menu list. When the title is highlighted press CONFIRM to edit.
2. Use function buttons appropriate to edit each setting then press CONFIRM to save the setting.
Note: For Main/Sub setting, select "Main" (Initial setting). Do not change the setting to "Sub", it is not avail-
able with FTC2BR.
Water temp. setting
Set the initial value of the set water temperature for following modes.
• DHW mode
• Heating mode
• Cooling mode
• Holiday mode
The set water temperature is changeable in main screen during operation.
Compensation curve
During late spring and summer usually the demand for space heating is reduced. To prevent the heat pump from
producing excessive flow temperatures for the primary circuit the compensation curve mode can be used to maximise
efficiency and reduce running costs. The compensation curve is used to restrict the flow temperature of the primary
space heating circuit dependent on the outdoor ambient temperature. The FTC2BR uses information from both an
outdoor ambient temperature sensor and a temperature sensor on the primary circuit supply to ensure the heat pump is
not producing excessive flow temperatures if the weather conditions do not require it.
Preview:
You can check the target water temperature in compensation curve. Select outdoor ambient temp. with F3 and F4 buttons.
Edit (Installer level):
Pressing F1 or F2 will cause the relevant edit screen to be displayed.
Press F1 to edit the flow temperature of Lo outdoor ambient temperature point.
Press F2 to edit the flow temperature of Hi outdoor ambient temperature point.
See the following for more detailed explanation of editing.
In the parameter edit screen the flow temperature and outdoor ambient temperature for the compensation curve graph
can be set and altered for the 2 extremes of Lo and Hi.
1. Press F1 and F2 to change the flow temperature (y-axis of compensation curve).
2. Pressing F1 will lower the desired flow temperature for the set outdoor ambient temperature.
3. Pressing F2 will raise the desired flow temperature for the set outdoor ambient temperature.
4. Press F3 and F4 to change the outdoor ambient temperature (x-axis of compensation curve).
5. Pressing F3 will lower the outdoor ambient temperature for the set flow temperature.
6. Pressing F4 will raise the outdoor ambient temperature for the set flow temperature.
