Function

The temperature humidity sensor STH01 mea-

sures the temperature and relative humidity cy-

clically and sends these values to a compatible 

ELDAT Smarthome-Server APC01. 
After inserting the battery, the sensor is immedia-

tely ready for operation and the current measured 

values are transmitted via radio telegram.
After the last transmission, the current values are 

automatically transmitted every 10 minutes. 
The current values can be transmitted manually 

by pressing the front area of the button.
During each transmission, the transmission LED 

lights up briefly. 
The STH01 fits into the most switch frames with 

the dimensions of 55x55 mm.

Start-Up  

 

1.  Screw or stick the mounting plate to the instal-

lation site. 

 

Attention

! Make sure there is no interference 

with the wireless connection. Do not mount 

the device in a distribution box, in metal cas-

ings, in direct proximity to large metal objects, 

on the floor or close to it.

2.  Insert the batterie (C) in the transmission mo-

dule (B2). The positive pole has to be  visible! 

3.  Place the cover frame (D) onto the mounting 

plate (E) and snap the transmission module 

(B) to the catches (F) on top and bottom. The 

arrow on the sensor module has to point up-

wards. 

4.  Snap the button (A) onto the transmission 

module (B).

Programming the transmission code

into the receiver

To program the sensor into the Smarthome ser-

ver, please follow the instructions given in the 

app. 
As soon as you are prompted to do so, press the 

rear learning button PTx to send the program-

ming telegram.
You can then press the front button (A) to trans-

mit the current measured values.
