BT52- RECEIVER
The BT52 receiver is a unit that connects directly to the boiler via the OpenTherm communication line. Its function
is to obtain the necessary information from the boiler and pass it on to the transmitter unit.
Installation and commissioning of the receiver should be performed by a SERVICE TECHNICIAN in accordan-
ce with the procedure described below!
ASSEMBLY BT52- RECEIVER
Install the receiver in a suitable place where its operation will not be affected by interference. Install it as far away as possible from large
metal objects (min. 0.5 m) due to poor signal reception. When installing, make sure that no power lines pass around the receiver.
We recommend that the installation is carried out by a person with the appropriate electrical qualification!
In case of unprofessional intervention and damage, the product loses the warranty!
1. Attach the BT52 receiver to the wall using double-sided adhesive tape.
2. We bring the OT communication double line from the boiler to the terminal block marked LINE OT +. Initialization starts no
LED is blinking on the processor (this may take up to 10 minutes).
We recommend using an external source AD05-Jack (not
included), which ensures continuous power supply of the receiver and trouble-free operation.
Wireless mode testing
As soon as the red Error LED starts flashing it is possible, after commissioning of the transmitter, to perform a wireless com-
munication test. On the transmitter, press the button
MENU
and by turning the button
„ „ select the TEST mode and confirm with . By turning the button „ „ you initiate the test.
Receiver function in case of OT line failure
a) the receiver is powered only via the OT line => If the OT line fails, the receiver will lose power and will not work. A
message appears on the transmitter „TRANSMISSION ERROR“ the symbol appears „ „ and the inscription disappears „ RFM“.
The boiler will work according to its thermostat!
b) receiver powered AD05 => In case of OT line failure the receiver will still be powered, yellow diode LINE OT + stops
flashing and the „OT +“ symbol on the transmitter disappears within 4 minutes!
Receiver function in case of wireless connection to the transmitter
a) receiver has information on the outdoor temperature from boiler => Automatically switches to equithermal
control. If it has not been set, the thermostat will automatically select curve no. 12 with a shift of 2.5!
b) receiver
has no outdoor temperature information
from the boiler => It automatically switches to non-freezing
mode, where it heats for 30 minutes to the maximum temperature given in CONST 5 and does not heat for 3 hours!
