Position the Radiostat on a wall surface away from
obstructions and direct heat sources or draughts, in a room
that is warmed by the heating system. The fixing of the
transmitter can be done either with screws and wall plugs or
with the double side adhesive depending on the wall surface
quality (both supplied). See the side diagram as reference to
drill the wall. Distance between 2 holes is 60 mm, drill hole dia.
5 mm. In the case of using wall plugs, the transmitter box must
be open to fix the screws to the wall plugs from inside the box.
The opening of the transmitter must
be done pressing gently the lower
button and leverage on the upper
side. Fit the supplied two batteries
inside the transmitter with the
direction as indicated internally.
W
ARNING
! Do not touch the printed
circuit board of the transmitter as it
contains electrostatically sensitive
components.
F
UNCTIONS
The wireless RF room thermostat has the following functions:
•
Room thermostat: the internal temperature sensor detects
the temperature and, comparing with the set point, switches
ON or OFF the heating request. The temperature sensor is
located on the lower side of the item.
•
Battery low
•
Alarm of missing radio frequency communication on the
receiver.
•
Room temperature calibration
•
Automatic boiler switch ON for radio communication errors
(missing communication between receiver and transmitter).
L
OW BATTERIES
The two supplied batteries will last for approximately 2 years
under a normal usage. When the batteries are low, the LO
letters will appear on the display alternated to the room
temperature value. Follow the correct positioning of the
batteries according to the internal transmitter battery box
indications. Every time the batteries are removed the set
temperatures and the transmitter coupling code are maintained
memorized.

RRORS
•
In the case of missing communication between the receiver
and the transmitter, the red or green led on the receiver
starts to blink irregularly, after 350 sec of the communication
being lost.
•
The above error can happen either when the battery power
on the transmitter is low (battery icon ON on the transmitter
display) and when the location of the transmitter is not
suitable (too far a distance or internal home disturbs like a
concrete wall or electronic interference etc.).
•
Once the communication has returned, the transmitter
automatically returns to a normal working mode.
•
In the case of missing communication, the receiver will
automatically switch on the heating requested to the boiler
(the boiler switching on will depend on the summer/winter
position on the boiler dashboard, not from the thermostat
request). This will prevent freezing in case of missing
communication between the receiver and the transmitter in
winter position.
•
If the receiver is located at the limit of wireless maximum
distance, the receiver can lose the communication for a
while and then back to normal working mode.
•
In the case of missing supply to the receiver (electrical black
out), the communication will be lost but at the return of the
electricity, the receiver will automatically return to a
standard working mode according to the transmitter signal.
There is no requirement for any special operation on the
receiver/transmitter in the case of missing communication
unless it is necessary to change location of the transmitter.
