INSTALLATION AND OPERATING INSTRUCTIONS
Unlike the conventional thermostat, this control separates
the function in two units. The receiver serves for wiring con-
nections and heat on/off control. The transmitter serves as
EN
the user interface and for temperature sensing/control. The
two units are linked by radio frequency (RF). The RF com-
munication 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 communi-
cation is visible on the transmitter display.
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. Press
again to confirm or escape.
THE TRANSMITTER is a wall-mount-
ed 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.
THE RECEIVER is connected to the
boiler. 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 trans-
parent bubble button that incorporates
the button function, the green led func-
tion and the red led function.

NOTE 1 FOR RECEIVER: when the receiver is manually
moved to the ON or OFF relay position (heating request
ON or OFF), after few seconds the relay position will move
according the transmitter request.
NOTE 2 FOR RECEIVER: in case of missing radio commu-
nication (see errors paragraph), the receiver relay moves
automatically to the ON position whatever the transmitter
request was (led green irregularly blinking). However it is
possible manually move the relay position (the heat re-
