NSTALLATION AND OPERATING INSTRUCTIONS

 

Unlike  the  conventional  thermostat,  this  control  separates  the 
function  in  two  units.  The  receiver  serves  for  wiring 
connections and heat on/off control. The transmitter serves as 
the  user  interface  and  for  temperature  sensing/control.  The 
two  units  are  linked  by  radio  frequency  (RF).  The  RF 
communication is only in one direction from the transmitter to 
the  receiver,  therefore  the  transmitter  does  not  receive  any 
feedback  from  the  receiver,  no  alarm  of  missing 
communication is visible on the transmitter display. 

T

HE  TRANSMITTER

  is  a  wall-mounted 

timer-thermostat.  The  transmitter  can  be 
located  wherever  a  conventional  room 
thermostat  would  normally  be  sited.  No 
wiring  is  required,  as  the  transmitter  is 
battery powered. 
 

T

HE  RECEIVER 

is  connected  to  the  boiler, 

and 

can 

replace 

conventional 

mechanical  or  electronic  time  clock.  The 
receiver  arrives  pre-cabled  and  ready  to 
be  fixed,  therefore  it  is  not  necessity  to 
open the receiver casing. The receiver is 
equipped  with  a  transparent  bubble 
button  that  incorporates  the  button 
function,  the  green  led  function  and  the 
red led function. 
Button functions: 
1. Press once: manually switch ON the heating (relay closed), 

press again to switch OFF. 

2. Press  for  5  seconds:  encoding  procedure  start  up.  After 

success  coupling  there  is  an  automatically  exit  from  the 
procedure.
