Cut or break out the outlets to the required connection points at the bottom of 

the receiver unit, in order to be able to connect wires to them.

9.2 Putting the receiver unit into operation

Turn on the power supply to the receiver unit. A few seconds after the LED 

lights flash once, the receiver unit becomes ready for operation. This state is 

indicated by the blue LED light with the "

A/M

" sign. After this, you can start 

tuning the receiver and the thermostats together. For this purpose press a 

button on the receiver associated with one of the heating zones and keep 

it depressed (for approximately 3 seconds) until the red LED light next to 

it  starts  flashing.  After  this,  press  the  “

SET

” button of the thermostat and 

keep it depressed then press the “

DAY

” button of the thermostat and keep it 

depressed too (for approximately 10 seconds) until the notice " " appears on 

the display. Next, select the same number as the number of the heating zone 

selected on the receiver unit using the large

 

 

and

 

 

buttons. Following 

this, press the “

COPY

” button and keep it depressed (for approximately 3 

seconds)  until  the  red  LED  light  on  the  receiver  stops  flashing  (it  remains 

switched on or off depending on the set and measured temperatures). Finally, 

press the “

SET

” button, so that the receiver unit “learns” the safety code of the 

transmitter (thermostat). The safety code will not be lost even during a power 

outage, the device memorizes it automatically. 
After tuned together, the receiver unit receives switching signals from the 

thermostats, controls the boiler (or air conditioner) and gives commands 

to open/close the heating zone valves (max. 4 zones, loadability of the 

zone outputs: 230V AC, max. 1A (0.5A inductive load)) associated with the 

thermostats. The receipt of switching signals is indicated by the switched 

on or off state of the red LED light associated with the thermostat on the 

receiver. By repeating the above steps, tune all of the thermostats and the 

receiver together.

ATTENTION!

 

Pressing the “

SET

” and “

DAY

” buttons simultaneously for 10 

seconds and then pressing the "

COPY

" button generates a new safety code 

for  the  thermostat,  and  the  receiver  will  recognize  it  only  after  a  repeated 

tuning. With this in mind, do not repeat the tuning steps without any reason 

after the units have been tuned successfully.
