1. Battery life is calculated with 720 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 1.5 V L91 lithium batteries in the battery compartments.
3. Pair the receiver and sensor if necessary. See description in the
variable list for the receiver RCW-M32.
4. Ensure that the receiver and sensor are paired by pressing the
Test
button
while studying the LED indications. See
.
5. Make a signal strength test as described under
.
6. Mount the sensor on a wall using the mounting holes. For optimal
monitoring, the sensor should be mounted in an open space with
good air circulation, and at a height of 1.2 to 1.4 meters.
7. Snap on the cover.

Settings
The temperature and humidity are 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.
N
No
ottee!! Changing the time intervals will influence the battery life time.
Handling
Signal strength test
Test the signal strength to optimise the installation:
1. Push the
Test button
(approx. 7 s) on a paired sensor until the LED
first shines with a solid light. After that the LED behaviour will
depend on the 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
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 temperature and humidity sensor is designed to work together with
Regin's wireless receiver RCW-M32 with Modbus communication.
