This thermostat is designed to be used

only with heating controls system with a

maximum switching load of 2A at 30VDC

or 0,25A at 230VAC or with Beretta

boilers fitting a bus protocol connection

If installing for someone else, please

ensure that the instructions are handed to

the householder.

Warning: Please read this manual prior

to installation or use.

Shock Hazard: This unit must be

installed by a competent person, in

accordance with local regulation, or other

relevant national regulations and codes of

good practice. Always isolate the AC

Mains supply before installing this unit.

Directive 1999/5/EC

Installation warning:

This programmer can be used either as a

central heating ON/OFF thermostat and

as boiler remote control (only with

selected Beretta boilers), therefore is

mandatory to determinate the correct

working mode (denominated TYPE)

before installation and setting.

From the main menu select the TYPE

parameter and those are the following

option:

Type

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 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.

The receiver is connected to the boiler,

and can replace a conventional

mechanical or electronic time clock.

Important: these instructions should be

read in conjunction with the appliance

installation instructions. It is

recommended that this device is installed

by a qualified electrician.

Eventual additional electronic boards

necessary to connect the controller to the

and need to be purchased separately.

REPARATION

:Isolate the appliance from

the electrical supply and remove the

appliance casing and PCB cover (refer to

boiler installation instructions for specific

details).

Connect the spade terminals of the

receiver to the boiler side. The 4 cables

have different color and different function.

Blue = main supply 230 Vac = neutral N

Brown = main supply 230 Vac = line L

Black & Black = OT+ boiler remote

control connection (bus protocol).

Red & Red = T.A. boiler ON/OFF room

thermostat connection

The choice between the two options

(defined as installation TYPE) depend

from the boiler capability and from the

installer decision. See picture for the

receiver internal connections.

Important: the link-wire (if fitted) must be

removed from room thermostat terminals

(both installation type)

Important: Secure the receiver wiring

harness to the internal boiler cable

anchors

Important: never connect the OT+

contact to 230V supply to avoid the

destruction of the bus circuit.

NSTALLATION OF RECEIVER

Secure the receiver in the proximity of the

boiler using 2 anchors (see picture below

for drill holes specifications) and screws

or the enclosed double side adhesive.

The location should be chosen in order to

see the receiver leds and have access to

the receiver encoding button. For no

reason should the receiver box be

opened. The appliance can only be

mounted indoors and in areas free from

any water or moisture. Wiring must

conform to IEE regulations. RF Address

Code Setting: if there is another user

nearby, e.g. in the next dwelling, your

receiver may be operated in error by their

transmitter. You may select a different RF

address code to prevent this. (see

encoding section on the technical menu

list).

Note: do not fix the receiver to the boiler

casing.

NSTALLATION OF TRANSMITTER

Before installing the transmitter check the

encoding functionality while the receiver

and the transmitter are still very near. The

encoding between the transmitter and the

receiver is already factory set therefore

there is not necessity to make any

encoding operation after installation (both

installation type) - follow the encoding

instruction if the communication is

missing or lost.

Before fixing the transmitter check that

the radio signal is active in the room that

you are fixing (if there is no

communication the receiver will flash

orange after 350 sec the communication

is lost). Because the transmitter uses

radio waves to communicate with the

receiver, you should also bear in mind

that metallic objects can weaken or

deflect radio signals: this includes steel

reinforced walls, filing cabinets, kitchen

appliances, mirrors. The range of the

Radiostat is 40 metres in open air, and 20

metres inside buildings, dependent on RF

obstructions as mentioned above.

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

the anchors and screws or with the

double sided adhesive (both supplied).

See the diagram below as reference to

drill the wall.

In the case of using anchors, the

transmitter box must be open to fix the

screws 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 to

open, follow the diagram for an easier

opening procedure.

ARNING

not touch the printed circuit

board of the transmitter as it contains

electrostatically sensitive components.

UNCTIONS

The Beretta Programmable 7-day RF

Thermostat has the following functions:

Type Room thermostat (crt): for the

display appearance in this mode, please

refer to the relevant section of this

manual. The internal temperature sensor

detects the temperature and, comparing

with the set point, switches ON or OFF

the heating request (according the

programmed timing). The temperature

sensor is located on the left side of the

item.

Temperatures: there are two level of

selectable temperature:

Comfort temperature T1 and economy

temperature T2 (T1 always > T2).

Both are selectable. Additionally there is

a third level of temperature indicated as

frost protection temperature that is

active all the time (the frost protection

temperature is selectable only inside the

technical menu. T2 always > Frost

protection temperature)

Time: on the display it is possible to set

and read the time (24 hours display

mode)

Day: on the display it is possible to set

and read the day of the week

Programming timing: it is possible by

selecting the relative timing fascia to

select the desired time. The programming

is possible during 7 day 24-hours and the

minimum time fascia is 30 minutes. The

programming is possible in two separated

temperatures: COMFORT (T1 ) and

ECONOMY (T2 ).

Status mode in crt: select the heating

mode button for fast switching between

the 4 status OFF – AUTO – PARTY -

HOLIDAY.

OFF mode, the heating request to

the boiler is off, on display there is not

equivalent icon, the heating layer and the

programming fascia is off. With this mode

only the frost protection function is active.

AUTO mode: the heating request is

according the programmed timing and
