2.3 Activate Install mode on Remote Controller (fig. 1)
• When the batteries have been connected, follow the installation guide, beginning with
the selection of language.
• After the installation process, set time and date by using the up/down selector  and
the left/right selector . Confirm settings with OK.
• The installation process is concluded with the opportunity to name the rooms in which
the room thermostats are placed. This makes access to and handling of the system very
easy.
• In the Name rooms menu, activate the Change with soft key 2 () to change the de-
fault room names (e.g. from “MC1 Output 1.2” to “Living room”), and confirm with OK.
You can also use the Spell…. menu to create other names.
• When the installation is finished a start up screen with actual time and date will be
shown in the display. The screen also shows actual temperature in the first room on the
rooms list (to select another room for the start screen, see chapter 5.1.2).
Note: Keeping a button activated during settings will make the value change faster.
3. Transmission Test
3.1 Initiate a transmission test on Remote Controller
Menu  Setup  Link test: From the start-up screen, select Link Test to activate a test of
the wireless transmission between Master Controller and Remote Controller. The status of
the link test will be displayed right after the test has been carried through.
If the link test is not successful:
• Try to relocate Remote Controller in the room.
• Or install a CF-RU Repeater Unit, and place it between Master Controller and Remote
Controller.
Note: The link test may take a few minutes, depending on the size of the system.

4. Mounting
4.1 Remote Controller has been installed (fig. 2)
When Remote Controller has been installed to Master Controller (see chapter 2), it can be
mounted on the wall by means of the back plate/docking station . This makes it possi-
ble to connect Remote Controller to a 230 V power supply with the included transformer/
power supply plug . When not in the docking station, Remote Controller is powered by
two AA Alkaline 1.5 V batteries.
• Before you place the back plate/docking station on the wall, verify the transmission to
Master Controller from the desired location by carrying out a link test (see chapter 3).
• Mount the back plate/docking station on the wall with the screws and wall plugs .
• Connect the docking station to a 230 V power supply outlet by means of the trans-
former/power supply plug .
• Place Remote Controller in the docking station .
Note: To extend the transmission range of the CF2+ system, up to three Repeater Units can be
installed in a chain (see fig. 4).
5. Menus
5.1 Rooms
Menu  Rooms: Activate the Rooms menu to access a list of all rooms in the system.
5.1.1 Select room
Menu  Rooms  Select room: From the Rooms menu, select the desired room. The
screen displays information about settings and actual temperatures:
Indicates that this room is included in an ongoing time program (see chapter 5.2).
Indicates that the room thermostat is running low on battery.
Indicates that the value set on the room thermostat is beyond the max./min. limita-
tions set by Remote Controller.
Indicates that the set temperature is above the actual tempe rature.
Indicates that the set temperature is below the actual temperature.

perature, indicated by the black bars above the time line (the periods outside the black
bars are the setback periods with reduced room temperature).
Set start and end times by means of the left/right selector and by toggling between them
using the up/down selector (fig. 1- /).
Note: A period with normal room temperature is removed by setting start and end to the
same time. The period is recreated by means of the up/down and left/right selectors.

5.3 Setup
Menu  Setup: From the start-up screen, activate the Setup menu to get access to a
variety of information and setting possibilities for Remote Controller as well as the entire
CF2+ system. As some of the setting possibilities in the Setup menu can affect the con-
figuration of the CF2+ system, and thus also the functionality of the entire application in
general, they should be handled with caution.
• Languages: Choose another language than the one selected during the installation
process (see chapter 2).
• Date and time: Provides access to setting of the date and time. Furthermore, this menu
includes settings for and activation of the summertime program. This enables you to
configure at what day, week and month the summertime begins and ends.
• Alarm: Switch the alarm buzzer of CF-MC Master Controller On/Off. The buzz only oc-
curs in case of an alarm, also indicated by the red alarm LED on Master Controller (see
fig. 3-). The Alarm log provides specific information about the error causing the alarm
and the time for its registration by the system. This Alarm log saves the latest alarms for
later access and easy system failure identification.
• Start-up screen: Choose which room temperature shall be displayed on the start-up
screen.
• Service: Configure all the outputs of Master Controller for either a floor or radiator heat-
ing system (regulation according to PWM (Pulse Width Modulation) principle). A mixed
system with floor and radiator heating in separate rooms can be selected by setting
the outputs of Master Controller individually for each room to either floor or radiator
heating (see chapter 6).
• Contrast: Adjust the contrast of Remote Controller display.
• Link test: Activate a test of the wireless transmission between Master Controller and
Remote Controller (see chapter 3).
• Identify Master Controller: Identify a specific Master Controller in a system of up to
three Master Controllers. When this function is activated, the Master Controller, you
wish to identify, will flash all the output LEDs from 1 to 10 and back again several times
for easy identification (option only available for systems with more Master Controllers).
