To be used only when boiler is set in a

zone valve management mode. Boiler

remote control using a bus protocol to

communicate with the boiler. Connect

the cable to remote control connection

on the boiler. Additionally the wired

device activate the ON/OFF built in

relay at any room heat request directly

to the zone valve.

:Eventual additional electronic

boards necessary to connect the

controller to the boiler main board are not

included in this box 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).

NSTALLATION OF PROGRAMMER

Position the programmer 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.

LECTRICAL CONNECTION

On the back side of the programmer,

once open, there are 2 couple of

connections.

Connection indicated as OT (printed on

the PCB) = use this when use the

programmer as remote control (type rEc)

Connection indicated as RELAY

(printed on the PCB) = use this when use

the programmer as room thermostat (type

crt).

Important: never connect the OT+

contact to 230V supply to avoid the

destruction of the bus circuit.

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

removed from room thermostat terminals

(both installation type)

ARNING

select the equivalent

programmer type as installed on the main

menu and remove the batteries after if the

type rEc is selected.

UNCTIONS

The Beretta Programmable 7-day

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

room temperature. In AUTO mode it is

possible to increase or decrease

temporary the room set temperature by

pressing the and buttons, only if

the current time is inside in a heating ON

fascia. The temporary new temperature

set (T1) is maintained only inside the

timing fascia. The next heating fascia will

be back to the original T1 set

temperature. It is possible to check the

set temperature by pressing once the

or the buttons only if the current time

is inside in a heating ON fascia.

HOLIDAY mode with choice how

many day off (by increasing or decreasing

using the button and ). The

heating request to the boiler is to maintain

the economy temperature on the room

(T2). The number of days off is

considered on the day starting from

midnight. After the counter down is ended

the programmer switch to AUTO mode.

PARTY mode automatically switch

the programmer ON to comfort

temperature (T1). This status is forced up

to midnight, after, the programmer goes

back to the programmed timing fascia.

Type Remote Control (rEc): 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, calculates the most

suitable boiler flow temperature according

the climatic curve (only if the external

sensor is fitted) and according the

velocity the set temperature is reached.

The programmer continuously

communicates with the boiler control

indicating the target flow temperature (the

values not just an ON/OFF) according to

the calculation made. With this type of

communication it is possible also to

adjust by remote the domestic hot water

(DHW) temperature in case of

instantaneous DHW production or DHW

storage tank controlled by a dedicated

sensor.

The functions of this type (rEc) are the

same as room thermostat type above
