Installation Guide
Setting up the system
Common settings for entire system (set once)
• Use the
key to choose INSTALL mode.
• Choose actuator type, press
will be marked on the actuator.
• Choose regulation type, either PWM+ or ON/OFF, by pressing the Mode key
Choose INSTALL mode
Use the
key to toggle to Install and confirm with OK. The Master Controller is now ready to include ther-
mostats.
Include thermostats and assign outputs
1. Touch the screen of the thermostat to make it search for the master controller and include the thermostat
into the system.
2. When the available outputs are flashing choose the output(s) on the master controller, which the thermostat
must control (Quick Guide D5). The available outputs will have a flashing LED.Once output is assigned to a
thermostat, it will be permanently lit. Confirm with OK.
Note! Do not turn off Master Controller while assigning RT to outputs.
3. Repeat step 1–2 for all rooms until all thermostats and outputs are paired.
Final test and starting system in normal run mode
Choose "test" mode by pressing
1. Net Test. Performs a full network test. The thermostats must be mounted in their final position when start-
ing the test. We recommend that you always perform this test in a wireless system, to make sure that all
thermostats can still communicate with the Master Controller, when in their final position. (Quick Guide E7).
This test can run for up to 90 minutes, but you can accelerate the test by touching each thermostat (to wake
it up).
During the network test the connection to Master controllers, Repeaters and Room thermostats will be tested.
During the test the display will inform which device it currently being tested.
rt = Room thermostat
MAS = Master controllers
rEP = Repeaters
While testing the connection to the room thermostats (Rt) the actuator outputs
connection to the thermostat connected to the output(s) have been tested.
When successful the outputs LED will light up permanently. When the network test is successfully com-
pleted the display will show Net Test Done.
2. App Test. Performs an application specific test if the expansion module is fitted. Tests all sub-components
and allows installer to verify correct functionality visually – step by step.
3. Flo Test. Force opens all outputs and activates circulation pump. Run for 30 minutes, but can be stopped at
any time. Use to bleed air from system before going into normal operation.
4. When you have conducted the needed tests, choose "run" mode by pressing
the system is now fully operational.
Connecting more Danfoss Icon™ Master Controllers in a system
If wired system
Connect up to three Danfoss Icon™ Master Controller 24V to each other with a 4-wire twisted pairs cable and
the supplied connector (pic. 10: A – 4 (2 × twisted pairs), B – Max. 3 x Master Controllers in one system). See data
table in the back of installation guide for wiring recommendations.
If wireless system
Wireless connection of up to three Danfoss Icon™ Master Controllers 24V requires a Radio Module with each
Master / Slave (pic. 11).
Pairing System Master and Slave in both wired and wireless systems
Note! Slave Controllers must be assigned as System Slaves before assigning outputs and thermostats to them.
1. On the selected system master, press
2. On the system slave, press and hold
TYPB.
to choose between the two slave types and confirm with OK. See "Slave type definition" section
3. Press
for explanation.
4. Repeat step 1–3 to assign a second Slave Controller to the system (max. two slaves are permitted).
Test procedures for multiple Danfoss Icon™ Controllers in a system
NET TEST on System Slave (after connecting slave to master)
1. Install all thermostats and actuators as described in the Quick Guide D2 to D6.
2. Perform Network test. Press
Guide E7 and E8).
3. After completing the TEST press
APP TEST on System Master
1. Perform application test. Press
Guide E7 and E8).
2. After completing the TEST press
Changing Slave type
1. On Danfoss Icon™ Slave Controller press and hold
TYPA and SLA TYPB.
2. Press
to choose between the two slave types and confirm with OK. See "Slave type definition" for more
information.
LINK test on Slave (between Master and Slave)
Press
for 1,5 sec. The display shows inclusion pattern while making the LINK test. When done, the display
shows the strength of the connection in percentage.
Note! If an Expansion Module is added to the system, it must be installed on the Master Controller.
Slave type definition
The potential free relay is activated on all Master Controllers when heat is demanded on either Master Controller.
SLA TYPA: Pump is activated on Danfoss Icon™ Master Controller 24V when heat is demanded on either Master
or Slave(s).
SLA TYPB: Pump relay is only activated on the Danfoss Icon™ Master Controller 24V to which the thermostat
with heat demand is assigned.
