INSTALLATION AND OPERATING INSTRUCTIONS

Unlike the conventional thermostat, thiscontrol separates the function in twounits. The receiver serves for wiringconnections and heat on/off control. Thetransmitter serves as the user interface

and for temperature sensing/control. Thetwo units are linked by radio frequency(RF).The transmitter is a wall-mounted timer-thermostat. The transmitter can be

located wherever a conventional roomthermostat would normally be sited. Nowiring is required, as the transmitter isbattery powered.The receiver is connected to the boiler,

and can replace a conventionalmechanical or electronic time clock.Important: these instructions should beread in conjunction with the applianceinstallation instructions. It is

recommended that this device is installed

by a qualified electrician.PACKING LIST QTYRF receiver with 6 wires fitted 1RF transmitter 1Anchors and screws 4

installer decision. See picture for thereceiver internal connections.Important:the link-wire (if fitted) must beremoved from room thermostat terminals(both installation type)

Important: Secure the receiver wiring

harness to the internal boiler cableanchorsImportant: never connect the OT+contact to 230V supply to avoid thedestruction of the bus circuit.

INSTALLATION OF RECEIVERSecure the receiver in the proximity of theboiler using 2 anchors (see picture belowfor drill holes specifications) and screwsor the enclosed double side adhesive.

The location should be chosen in order tosee the receiver leds and have access tothe receiver encoding button. For no


8/28

reason should the receiver box be

opened. The appliance can only bemounted indoors and in areas free fromany water or moisture. Wiring mustconform to IEE regulations. RF AddressCode Setting: if there is another user

nearby, e.g. in the next dwelling, yourreceiver may be operated in error by theirtransmitter. You may select a different RFaddress code to prevent this. (seeencoding section on the technical menu

list).Note:do not fix the receiver to the boilercasing.

INSTALLATION OF TRANSMITTER

Before installing the transmitter check theencoding functionality while the receiverand the transmitter are still very near. Theencoding between the transmitter and thereceiver is already factory set therefore

there is not necessity to make any

encoding operation after installation (bothinstallation type) - follow the encodinginstruction if the communication ismissing or lost.Before fixing the transmitter check that

the radio signal is active in the room thatyou are fixing (if there is nocommunication the receiver will flashorange after 350 sec the communicationis lost). Because the transmitter uses

radio waves to communicate with thereceiver, you should also bear in mindthat metallic objects can weaken ordeflect radio signals: this includes steelreinforced walls, filing cabinets, kitchen

appliances, mirrors. The range of theRadiostat is 40 metres in open air, and 20metres inside buildings, dependent on RFobstructions as mentioned above.


9/28

Position the Radiostat on a wall surface

away from obstructions and direct heatsources or draughts, in a room that iswarmed by the heating system. The fixingof the transmitter can be done either withthe anchors and screws or with the

double sided adhesive (both supplied).See the diagram below as reference todrill the wall.

In the case of using anchors, thetransmitter box must be open to fix thescrews to the anchors internally the box.See the diagrams below for removal from

and re-assembly to backplate. Pay

attention because it could be difficult toopen, follow the diagram for an easieropening procedure.

WARNING!DOnot touch the printed circuitboard of the transmitter as it containselectrostatically sensitive components.

FUNCTIONSThe Beretta Programmable 7-day RFThermostat has the following functions:Type Room thermostat (crt): for thedisplay appearance in this mode, pleaserefer to the relevant section of thismanual. The internal temperature sensordetects the temperature and, comparing


10/28

10

with the set point, switches ON or OFF

the heating request (according theprogrammed timing). The temperaturesensor is located on the left side of theitem.Temperatures: there are two level of

selectable temperature:Comfort temperature T1 and economy

temperature T2 (T1 always > T2).Both are selectable. Additionally there isa third level of temperature indicated as

frost protection temperature that isactive all the time (the frost protectiontemperature is selectable only inside thetechnical menu. T2 always > Frostprotection temperature)

Time:on the display it is possible to setand read the time (24 hours displaymode)Day: on the display it is possible to setand read the day of the week

Programming timing: it is possible by

selecting the relative timing fascia toselect the desired time. The programmingis possible during 7 day 24-hours and theminimum time fascia is 30 minutes. Theprogramming is possible in two separated

temperatures: COMFORT (T1 ) andECONOMY (T2 ).
