1. Battery life is calculated with 288 wake-ups and 120 value updates per day.
Installation
1. Open the cover by pressing the locking tab carefully with a screwdriver.
2. Insert two CR123A lithium batteries in the battery compartments.
3. Pair the receiver and sensor if necessary. See description in the variable
list for the receiver MR32W.
4. Ensure that the receiver and sensor are paired by pressing the Test
button shortly while studying the LED indications. See Handling.
SEW-PT1000
5. Make a signal strength test as described under Handling.
6. Connect the external PT1000 sensor if used.
7. Mount the sensor on a wall using the mounting holes.
8. Snap on the cover.

DIP switch Description
1 Frequency
OFF = 868.6375 MHz (used in Europe)
ON = 868.2375 MHz (used in China)
2 Internal/external sensor
OFF = Internal
ON = External
Settings
The temperature is measured at an adjustable time interval called wake up
time. If a measured value changes more than the specified limit it will send a
signal to the receiver. The sensor will always send a signal to the receiver
every 95 - 110 minutes. If the receiver does not receive a signal from the
sensor within a specified time interval it will indicate out of signal.

For default time values, limits and how to modify them see the variable list
for the receiver.
Note! Changing the time intervals will influence the battery life time.
Handling
Signal strength test
Test the signal strength to optimise the installation:
ON
1. Push the Test button (approx. 7 s) on a paired sensor until the LED first
5
shines with a solid light. After that the LED behaviour will depend on the
1 2
connection quality.
– Long flash with short pause = Very good connection (-20...-50 dB)
– Short flash with short pause = Good connection (-50...-90 dB)
– Flash with long pause (1 s) = Bad connection (< -90 dB)
– No LED = Out of range or time-out for test sequence
3
2. Test in different locations to optimise the connection before installing
the unit.
The test sequence lasts for 1 minute.
LED indications
– 3 flashes (when Test button is pressed): The sensor is not paired with
the receiver.
– Flashing (when Test button is pressed): The sensor is paired with the
receiver.
– Flash every 4 seconds: Batteries need to be replaced.
Function
The outdoor temperature sensor is designed to work with our wireless
receiver MR32W with Modbus communication.
