Offset (sensor offset)
- The temperature measured on-site can vary slightly from the room temperature if the Du-modern Room Thermostat 9485 is installed in an unfavorable position (e.g. behind a curtain or on a cool exterior wall)
- An adjustment of the measurement in the range of – 5.0°C to + 5.0 °C can be carried out using the sensor offset

General view of the Remote Sensor 9485-F
Functional description
The Remote Sensor 9485-F is used to connect to the DuoFern Room Thermostat
9485.
The Remote Sensor 9485-F is optionally available as an external temperature
sensor if the internal sensor cannot reliably record the room temperature.
This may be useful if:
- The DuoFern Room Thermostat 9485 is installed in a thermally unfavorable position (e.g. on a cool exterior wall)
- Heavy loads (e.g. an electric heater) are switched on that significantly heat up the DuoFern Room Thermostat 9485 (self-heating)
Absolutely essential
If you are using the DuoFern Room Thermostat 9485 as a temperature limiter
(e.g. for floor heating with special floor coverings), it is absolutely
essential to use the Remote Sensor 9485-F as an external temperature sensor.
You can set up the appropriate configuration depending on the operating mode
selected for the DuoFern Room Thermostat 9485.
To do so, please read the instruction manual for the DuoFern Room Thermostat
9485.

Safety instructions
The use of defective devices can lead to personal injury and damage to
property (electric shocks/short-circuiting).
◆ Never use defective or damaged devices.
8.1 Intended use
Use the Remote Sensor 9485-F only to connect the DuoFern Room Thermostat Type
9485.
8.2 Improper use
Using the Remote Sensor 9485-F for any other purpose than previously mentioned
is not permissible.
8.3 Required expert knowledge of the installer
The electrical connection, installation, and commissioning of the Remote
Sensor 9485-F must be carried out by a qualified electrician with basic
heating control knowledge in accordance with the instructions in this manual.
Safety instructions for the electrical connection
Read the specifications relating to the electrical connection detailed in the instruction manual of the DuoFern Room Thermostat 9485.
DANGER!
There is a risk of fatal electric shock when touching electrical components.
- All connection and installation work must only be carried out in an isolated, de-energized state.
- Disconnect all phases of the mains power cable to the room thermostat and secure it to prevent any reconnection.
- Check that the system is de-energized.
- As the remote sensor has 230 V potential, the cabling of the sensor (e.g. with an extension) must have basic insulation (against contact).
WARNING!
Incorrect wiring may lead to short-circuits and destroy the device.
Follow the pin assignment detailed in the connection diagram.
9.1 Important information regarding the electrical connection
The maximum length of lead
The maximum length of the lead to connect the Remote Sensor 9485-F must not
exceed 10 m.
9.2 Electrical connection
The Remote Sensor 9485-F must be connected with the terminals of the DuoFern
Room Thermostat 9485 marked with “S” and “N”.
-
Ensure that the mains power cable to the DuoFern Room Thermostat 9485 is current-free and check that the mains power cable is current-free.
-
Remove the insulation on all leads down to 6 mm in length.
-
Connect the cable end sleeves provided to the stripped ends of the connecting cable.
Use a suitable crimping tool (crimper). -
Connect the Remote Sensor 9485-F in accordance with the connection diagram.
-
Securely lay all connecting cables right into the flush-mounted box.
-
The installation of the DuoFern Room Thermostat 9485 into the flush-mounted box is carried out after the electrical connection.
The desired operating mode can be set in menu 9.7.1 and the external temperature sensor can be activated after the connection.

Installing the remote sensor
Do not lay the cable of the Remote Sensor 9485-F parallel to the live mains power cable if at all possible.
-
Select a suitable installation site.
You should position the Remote Sensor 9485-F centrally between two heating conductors to achieve the best possible heat distribution in the floor. -
Lay the connecting cable and the Remote Sensor 9485-F in a conduit.
This makes it easier to replace the Remote Sensor 9485-F at a later stage (e.g. in case of a defect). -
Seal the conduit with an appropriate protective sleeve.
Settings on the DuoFern Room Thermostat 9485
You can configure the necessary settings in menu 9.7
“Installer settings”.
Read the specifications in the instruction manual of the DuoFern Room
Thermostat 9485.
Performing a sensor test
You can view the readings of the internal sensor and the Remote Sensor 9485-F
(as an external sensor) in menu 9.7.7 “Sensor test” to check the installation.
Setting the sensor offset
The sensor can be adjusted by an offset, see menu 9.7.2 “Sensor offset”,
should deviations in the temperature measurement occur (e.g. due to the length
of the lead and the contact resistances). An offset setting range of between
-5.0°C and +5.0°C (in 0.1°C steps) is possible.
11.1 Error messages on the DuoFern Room Thermostat 9485 Error 4
The temperature sensor provides invalid readings.
- Perform a hardware reset
- Please check the cabling
