With this program, you can set the room temperature for all Room Thermo-stats during e.g. a holiday. The start and end date for the program is easily set in a calendar by means of the up/down and left/right selectors (fig. 1- / ) and by confirming each setting with OK. The room temperature and the duration of the period program are illustrated and finally activated from a detailed overview for the created program:
Setback program:
In the Program setback menu, you have the opportunity to divide the different rooms into up to six different zones – each zone with up to three different setback programs for reduced room temperature at different times during the day.
Options
Each zone has a screen showing the rooms included in the zone. This provides access to an Options menu with an Add room function and three Setback programs (up to).
Add room
In this menu, all the rooms are followed by a ( ) indicating to what zone each room has been allocated (see figure below ). As default, all the rooms are assigned to Zone 1. If new zones are created, the rooms will be moved from the zone to which they are allocated to the new zone (from zone 1 to zone 3 in the figure below).
Program 1 – 3:
The Options menu also includes three possible setback programs for each zone. By means of these, the seven days of the week can be divided into up to three different setback programs with different days and setback periods for each program. The procedure for creating or changing a program is the same for all the three programs:
- Activate program (1- 3) from the Options menu with OK to select the days for GB this program:
- Use the up/down and left/right selectors (fig. 1- / ) to select the days for this program by moving them above the horizontal line. Confirm with OK, and activate the next step to select the time for the setback program.
- Select the time for the setback program by setting the times for the periods during which you want a normal room temperature, indicated by the black bars above the time line (the periods outside the black bars are the set-back periods with reduced room temperature). Set the start and end times by means of the left/right selector and by toggling between them using the up/down selector (fig. 1- 4/5 ).
You can remove the second period with the normal room temperature by changing the end time of this period to its start time:
The second period with the nor-mal room temperature 2 can be added again by means of the up/down selector and by toggling through the first period .
Confirm the selected time periods with OK to activate the created program from this overview:
Note: The days selected in the program are indicated by more distinct initial capitals
Cancel program:
A created program can be deleted with the Cancel Program menu leading to the overview illustrated above.
Note:
- In the Options menu, the created programs (1-3) will be indicated by more distinct capitals
- If you want to override a setback period in a room, you can do so with the Override setback function in the Options menu for each room (see chapter 5.1.1)
Setback temperature
In the Setback program (see chapter 5.2.2), activate the Setback temperature menu to set the room temperature reduction from 1 to 10°C during setback periods.
Setup
From the start-up screen, activate the:
Setup menu with access to a variety of information and setting possibilities for the Remote Controller as well as the entire CF2 system.
Note: As some of the setting possibilities in the Setup menu can affect the configuration of the CF2 system, and thus also the functioning of the entire application in general, they should be handled with caution
Languages:
Here you can choose another language than the one selected during the installation process (see chapter 2).
Date and time:
Provides access to the setting of the date and time. Furthermore, this menu includes the 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:
From this menu, you can switch the Buzzer of the Master Controller (MC) On/Off. The sound only occurs in case of an alarm, also indicated by the red alarm LED on the Master Controller (see fig. 3- ). In the Alarm log, you can get 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 ac-cess and easy system failure identification.
Start-up screen:
Here you can choose which room temperature you want displayed on the start-up screen.
Service:
Here you can configure all the outputs of the Master Controller (see fig. 5-a) for either a floor or radiator heating system. With floor heating, you can choose regulation by means of an On/Off or a PWM (Pulse Width Modulation) principle. Choosing a radiator system automatically sets the regulation to PWM. Even a mixed system with floor and radiator heating in separate rooms can be selected by setting the outputs of the Master Controller individually for each room to either floor or radiator heating.
Note: When the Master Controller is regulated by PWM, the cycle times are:
- Floor heating: 2 hours
- Radiator heating: 15 minutes.
In the Service menu, activate the Standby temperature function with OK in order to set a fixed room temperature for all the Room Thermostats to 5 – 35°C when the Global standby input is activated on the Master Controller (see instruction for Master Controller, CF-MC for installation details).

Link test:
Activates a link test to the Master Controller to test the wireless transmission to and from the Remote Controller (see chapter 3).
Identify Master Controller:
This function enables you to identify one specific Master Controller in a system of up to three Master Controllers. When this function is activated, the Master Controller, whose identity you wish to reveal, will flash all the output LEDs from 1 to 10 and back again several times for easy identification.
Alarms
If an error occurs in the CF2 system, it is indicated by the Master Controller and directly on the Remote Controller Display:
When the alarm is acknowledged with OK, the Buzzer of the Master Controller will go Off (if set to Sound On, see chapter 5.3), and the CF2 system will switch to Alarm status as indicated on the start-up screen: 
This indication of Alarm on the Remote Controller and the indication on the Master Controller will continue until the error that caused the alarm has been fixed.
An Alarms menu will be present at the top of the Menu list activated from the start-up screen:
Activating this Alarms menu with OK provides access to an Alarm status where you can see a description of the error causing the alarm Furthermore, you can select the Alarm log to get 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. When no error is causing an alarm, you can access the Alarm log through the Setup menu (see chapter 5.3).
