Master Controller 24 V
Er12
Actuator defective .
The defective actuator output is
flashing .
Replace actuator .
Er14
A
Danfoss
Icon
™
Master Controller
cannot be included as (become)
a Slave Controller because one or
more room thermostats, repeaters
or
Danfoss
Icon
™
Master Controller
24V have already been included .
This
Danfoss
Icon
™
Master Controller 24V has to
be factory reset to become a Slave Controller . (See
description in chapter ”Reset or replace a
Danfoss

™
Master Controller) .
Er16:
This application requires a specific
actuator output to be available .
You have already assigned this output to a
room thermostat, or the output has not yet had
an actuator fitted . Please remove output from
thermostat, it must be available to the application
chosen (or fit actuator - if this was not yet done)
Er17:
External PT1000 sensor not fitted,
or defective .
Check sensor and replace if necessary .
Hydraulic balance
When using the
Danfoss
Icon
™
Master Controller
24V
with PWM+ regulation, the system will auto-
matically balance the circuits .
In heating systems with extreme differences in cir-
cuit lengths, the automatic balancing might not be
adequate .
In these cases the
Danfoss
Icon
™
Master Controller
24V can help you determine which circuits that are
struggling to get enough flow:
1 . Press
to select RUN mode .
2 . Press an button to see the average duty cycle
in percentage for the selected circuit .
OK
When pressing the output button the average duty
cycle is shown in the display of the
Danfoss
Icon
™
Master Controller 24V .
The duty cycle is shown as the amount of time in
% that the actuator is open during active heating
periods and only when in heating mode as an av-
erage over time .
This feature can help determine if one or more
rooms have difficulty receiving enough flow or ef-
fect to reach optimal comfort .
The room with the highest duty cycles is the one
that calls for the highest flow . If this room has prob-
lems reaching the desired room setpoint temper-
ature, the following steps can help give this room
more flow/heating capacity:
1 . Increase the flow for the room with the high-
est duty cycle, using the pre-setting valve
on the manifold -> set to maximum flow on
pre-setting valves for this room’s outputs .
2 . If the room with the highest duty cycle is al-
ready at maximum flow, instead reduce the
flow for the outputs that show the lowest duty
cycle (these do not need as much flow) .
3 . If none of the above is enough to reach the
desired room temperature, increase the total
flow, by setting a higher flow on the circula-
tion pump .
4 . As a last resort increase the supply tempera-
ture into the system .
Note!
By installing an Expansion Module in the
Danfoss
Icon
™
Master Controller 24V
the system
will be able to automatically adjust the supply
temperature according to heat demand in the rooms.
