Installation Guide
Keys
1. Installer key
Used by the installer when setting up the system (used during installation).
• Select INSTALL for installing and configuring the system.
• Select UNINSTALL for replacing or removing a system component, e.g. a thermostat.
• Select TEST for finalizing the installation and to run one of three test types, either: Network test, Application test or Flow test
(i.e. flushing of system)
• Select RUN when all system devices are installed and a TEST is finished.
2. Mode key
Used for choosing the desired control behavior of the entire system (set once for the entire system).
• PWM+: Type of regulation designed to minimize overheating by dividing the heat demand into smaller bits (= duty cycles). The
length of a duty cycle varies depending on the chosen heat emitter. PWM+ also features auto balancing of flow to the different
rooms, which improves the heating comfort.
• On/Off: A simple hysteresis control, which turns on the heat when the temperature is below the desired room temperature.
The heat will not be turned off until the desired room temperature is reached.
3. Heat emitter key
Defines which heat emitter is used on the output (optimized control performance for each heat emitter type).
• Select SLOW for floor construction with >50 mm concrete over pipes (typically no heat distribution panels used).
• Select MEDIUM for floor or wall construction with <50 mm concrete over pipes (typically pipes laid onto heat distribution
panels).
• Select FAST for radiator or convector (supplied from a manifold).
4. Actuator type selector key
Used to define which kind of 24 V actuator is used (set once for the entire system).
M
• Select NC for normally closed (typically used).
• Select NO for normally open (rarely used).
5. Main user interface
• Press OK to confirm a setting.
• Press or to change a parameter value or toggle through menus.
• Use to go one step backwards in a menu.
6. Output selector keys
Used for assigning actuator outputs to a thermostat.
1
• Connect only one actuator wire per output terminal.
• Assign as many outputs as you want to a thermostat.
Depending on Danfoss Icon™ Master Controller model, you will have 10 or 15 outputs available.
Cable terminals
7. Upper terminal row
For connection of 24 V thermal actuators max. one actuator per output terminal.
8. Lower terminal row
For connection of 24 V thermostats in a wired system, or for additional 24 V wired thermostats in a wireless system.
9. Upper cable strain relief bar
Installed as final step of wiring, tighten screws to assure wire retention.
10. Lower cable strain relief bar
Clicks over thermostat cables to hold them in place. Top of this part also acts as cable holder for actuator cables.
11. Removable lid
Covers access to the 230 V section of Danfoss Icon™ Master Controller 24V. Remove the screw and slide out to access 230 V termi-
nals. This part can be replaced with the Expansion Module, if special applications are necessary.
Connectors
12. Radio Module connector (RJ 45)
Connect the Radio Module to this connector via cat. 5 patch cable (supplied with the Radio Module).
13. App Module connector (RJ 45)
Connect the App Module to this connector via cat. 5 patch cable (supplied with the APP Module).
14. 3-pole connector - for linking together multiple Master Controllers in a 24V system.
Only used in wired systems! Loose 3-pole male connector supplied with the product.
