Customising Settings for Your Home
[Heating/Cooling]
The heating/cooling menus deal with space heating/cooling using normally either
a radiator, fan-coil, or underfloor heating/cooling system depending on the instal-
lation.
There are 3 heating modes
Heating room temp. (Auto adaptation) (
●
Heating flow temp. ( )
●
Heating compensation curve (
●
Cooling flow temp. ( )
●
<Room temp. (Auto adaptation) mode>
This mode is explained in detail in 'Overview of Controls' Section (page 3).
<Flow temp. mode>
The temperature of the water flowing to the heating circuit is set by the installer
to best suit the space heating/cooling system design, and user's desired require-
ments.
Explanation of compensation curve
During late spring and summer usually the demand for space heating is reduced.
en
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 temperature. The FTC uses in-
formation from both an outdoor 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.
Your installer will set the parameters of the graph depending on local conditions
and type of space heating used in your home. It should not be necessary for you
to alter these settings. If however you find that over a reasonable operating pe-
riod the space heating is not heating or is overheating your home, please contact
your installer so they can check your system for any problems and update these
settings if necessary.
[Holiday mode]
Holiday mode can be used to keep the system running at lower flow temperatures
and thus reduced power usage whilst the property is unoccupied. Holiday mode
can run either flow temp., room temp., heating, compensation curve heating and
DHW all at reduced flow temperatures to save energy if the occupier is absent.
From the main menu screen press button E should be pressed. Be careful not to
hold down button E for too long as this will turn off the controller and system.
Once the holiday mode activation screen is displayed you can activate/deactivate
and select the duration that you would like holiday mode to run for.
Press button F1 to activate or deactivate holiday mode.
●
Use buttons F2, F3 and F4 to input the date which you would like holiday
●
mode to activate or deactivate holiday mode for space heating.
<Editing holiday mode>
Refer to the menu tree in "Main remote controller" of Installation Manual.
Should you require the Holiday mode settings e.g. the flow temp., room temp. to
be altered you should contact your installer.
