Danfoss Icon™ Master Controller 24 V
If wired installation
Note! Disconnect power before wiring!
For wiring of wired thermostats and actuators,
please refer to the Quick Guide sections B and C.
24V Thermostats can be wired either in BUS or Star
configuration, see below.
The system is not polarity sensitive.

Installation of App Module,
code no. 088U110
The App Module is required, when app function-
ality is wanted. For inclusion in a wireless network
(Wi-Fi), please refer to the App Module installation
guide. In systems with more Danfoss Icon™ Master
Controllers only one App Module is required, and
it can be added to any of the Master Controllers.
Wiring a pump
PWR1 output is intended for usage in installations
where a circulation pump is present in the system.
The PWR1 output has a live 230 V output (max. 100
W), which is activated when heat is demanded by
at least one thermostat. When no heat is demand-
ed from any thermostat the PWR1 output will be
turned off to save energy.
When heat is demanded the output will be acti-
vated with a delay of 180 sec. to prevent the pump
from running without being able to generate flow
due to the delay on the actuators in the heating
circuits.
Wiring a potential free relay
A potential free relay can be used e.g. to activate
heat demand/production from a boiler.
It is recommended to use the potential free relay
as heat demand signal for all boilers with appropri-
ate inputs available.
For boilers with 0-10 V modulation it is not
possible to use the heat demand signal from the
Danfoss Icon™ Master Controller 24V.
Please note that some combi-boilers may have hot
water prioritization, which can cause heat produc-
tion of the system to be delayed.
If wireless installation
Note! Disconnect power before wiring!
Connect a Radio Module, code no. 088U1103.
The Radio Module is required, when wireless ther-
mostats are installed. The radio module is supplied
with a 2m patch cable. A longer cable (max. 15m)
can be used if necessary.
One Radio Module must be fitted to each Danfoss
Icon™ Master Controller 24V in systems with more
THERMOSTAT Master Controllers.

Installation of Expansion Module,
code no. 088U1100 (Quick Guide E4).
Note! Disconnect power before inserting the Ex-
pansion Module.
Slide of the cover and insert the Expansion Mod-
ule. Follow the supplied instructions.
Note! If an Expansion Module is added to a system
with multiple Master Controllers, it must be installed
on the System Master.
Installation of a Floor Sensor (if 24V thermo-
stat), code no. 088U1110.
For installation of a floor sensor, please refer to
instructions supplied with the thermostat.
Rooms with both floor heating and radiators
controlled by one thermostat.
It is possible to have a mixed application with both
radiators and floor heating controlled by the same
Danfoss Icon™ room thermostat, if
• The thermostat has a floor sensor set up for
"dual mode" on the thermostat (set "DU" mode
in installer menu on thermostat).
• The radiator has it's flow controlled by an actu-
ator.
• Remember to set correct emitter type for rele-
vant outputs in said room.
In this application, the floor sensor is only used
to assure a min. floor temperature (if necessary, a
max. floor temperature can be set).
The built-in sensor is used to control the room
temperature by the assigned radiator output (the
fastest of the two output types).
Note! Only Danfoss Icon™ room thermostats with
floor sensor are supported.
