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 .
• 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 .
