4.9 More (2 to 3) CF-MC Master Controllers

Note! To have a troublefree installation of the CF-MC Master Controller 2 and/or 3, it is recommended to
complete installation of the CF-MC Master Controller 1.
CF-MC Master Controller 1 should be the one connected to the local supply pump.
• Up to 3 CF-MC Master Controllers can be connected in one system.
• If there are 2 or 3 CF-MC Master Controllers, connect them to a 230 V power supply within a
distance (max. 1.5 m) from CF-MC Master Controller 1, allowing simultaneous handling of all the
CF-MC Master Controllers.
Activate Install mode on CF-MC Master Controller 1 (fig. 20):
• Use the menu selection button
• Activate Install mode by pressing OK
Initiate installation on CF-MC Master Controller 2 or 3 (fig. 20):
• Activate installation to CF-MC Master Controller 1 by pressing OK
• Install LED flickers during communication and goes OFF when installation is complete.
• Relocate CF-MC Master Controller 2 and/or 3 if necessary. Link test will be initiated automati-
cally on reconnection to 230 V power supply.
• If CF-MC Master Controller 2 and/or 3 has it's own pump, the relays for pump and boiler must
be configured accordingly (see chapter 6.5).
Note! Later removal of CF-MC Master Controller 2 or 3 from CF-MC Master Controller 1 can only be done
by resetting CF-MC Master Controller 1 (see chapter 7.2).

4.10 CF-RS, -RP, -RD and -RF Room Thermostats

Note! Assignment of Room Thermostats to CF-MC Master Controller should be within a distance of 1.5 m.
Activate Install mode on CF-MC Master Controller (fig. 20):
• Use the menu selection button
• Activate Install mode by pressing OK
Activate Install mode on CF-RD and -RF Room Thermostats (fig. 20/21):
• Press the push button
Activate Install mode on CF-RS and -RP Room Thermostats (fig. 20/21):
• Press the push button
Select output on CF-MC Master Controller (fig. 20/22):
• All available output LEDs on CF-MC Master Controller
• Press output selection button
• All output LEDs
Room Thermostat installation status (fig. 21):
• Satisfactory: LED
• Not satisfactory: LED
Note! A Room Thermostat can be assigned to several outputs if needed by repeating the installation process.

4.11 Other System Components

The installation procedure of other system components to the CF-MC Master Controller (CF-RC Re-
mote Controller, and CF-RU Repeater Unit) is described in the enclosed instructions for these system
components.

4.12 Transmission Test (Link Test)

The transmission test (link test) between the CF-MC Master Controller and other system components,
is initiated from the other system components like CF-RU Repeater Unit, CF-RC Remote Controller,
etc. See the enclosed instruction for these components for transmission test (link test) procedures.
Room Thermostats
When the transmission test (link test) from a Room Thermostat is received by the CF-MC Master
Controller, the assigned output(s) will flash. This makes it possible to identify the outputs to which a
Room Thermostat has been assigned (fig. 22 -
