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 .
If BUS wiring (serial)
If Star wiring (parallel)

Installation of App Module,
code no . 088U1101
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 demanded
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 appropriate
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 2 m patch cable . A longer cable (max . 15 m)
can be used if necessary .
One Radio Module must be fitted to each Danfoss
Icon™ Master Controller 24V in systems with more
Master Controllers .
As a special feature, it is possible to include wired
thermostats in a wireless system .

For installation of wireless thermostats and actua-
tors, please refer to the Wireless Quick Guide sec-
2
tions B2, B3, B4 and C1 .
Installation of Expansion Module,
code no . 088U1100 .
Note! Disconnect power before inserting the
Expansion Module.
Slide of the cover and insert the Expansion Module .
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 in-
structions 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
actuator .
• Remember to set correct emitter type for relevant
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.
