product does not work as directed by the manufacturer consult the service department of

the manufacturing company (0030 210 2323345 ) .

Installing Installation:

The V-DCS3 device is enclosed in a box DIN RAIL BOX 6 fuses and can be mounted on

top hat rail box, table rail (see page 9) or directly on the wall.

The space that the device is positioned V-DCS3 should not wetted or not has a high mois-

ture level .

External cables connecting the power supply and signal cables is not necessary to cross to

exceed 1mm 2x1mm.

The cables connect the sensors of the device is not necessary that the cross-section not

exceed 0,50 mm 2x0, 50mm.

With the key you can browse the main setup menu (See page 8), and to reduce the val-

ues for each parameter we choose to modify. The button with the symbol functions as ON

-OFF to use the no auxiliary source applications 2 and 3 (see page 3 & 4), while in the main

menu setting as options to amend the parameter value as a ENTER fee and the modified pa-

rameter value.

The device V-DCS3 adjusted with 3 but-

tons on the left of the screen as shown in

Figure 1.

The device once placed under voltage

works according to the factory settings

(see page 8 TABLE 1) shown in the

menu. To see these settings or modify

them to press simultaneously for 3sec

and 2 buttons with symbols

With the key you can browse the

main menu setting or increase the values

for each parameter we choose to modify.

Handling:

Display first start: The device features a V-DCS3 backlit LCD 8 characters x 2

lines on a green background .

Connecting the power supply device is going through a

phase where starting and shown the first two screens se-

quentially as shown in Figure 2 . After booting the device

has started working normally reflecting successively 3,4,5

and 6 display continuously and repeatedly while making

temperature and other controls .

Screen 3: Message << SYS: number >> abbreviation of the

word SYSTEM is the first and basic parameter in the setup

menu to select the application you want to control our de-

vice ( see page 3 & 4) . Message << AUX: ON, OFF or NA

>> abbreviation AUXILIARY and reports the status of

OPEN , CLOSED or NO auxiliary source of DHW .

Screen 4 & 5: Message on screen 4 << S1: ° C >>, << S2: °

C >> and screen 5 << S3: NA >>, << S4: NA >> refers to

values of Celsius sensors at that time and detected accord-

ing to the application that we have chosen . The sensor S4

model V-DCS3 not applicable .

Screen 6 : Message << R1 R2 R3 >> shows the relay

status as controlled by our device at that time . The relay R3

model V-DCS3 not applicable .

Enabling first implemented 2 when S2 <MST-DAS.

Enabling a second application 3 when the S3 <MST-DAS.

! Caution : In applications 2 & 3 have control auxiliary source , the message << AUX >> should

be << ON >>.

3rd Enabling Implementation 4 when (S3-S2) ≥ DTS & S3 ≥ MCT when the elapsed time of the

delay parameter CPD.

4th Enabling Implementation 4 when S3 ≤ FPC frost protection panels. The process of opening

and closing operation of R2 is a time (120 sec) by repeating S3> FPC.

5th Enabling Implementation 4 when S3 ≥ MTC overheat protection panels. The R2 will be dis-

abled when S3 <MTC at 3 ° C or HST = MTC.

Operation:

The device V-DCS3 the time to be fed with electricity constantly performs checks proper func-

tioning sensory outputs and relay contacts are available . The green screen background after

10 sec disappears , comes back with the click of one of the three buttons .

Cases Trigger R1

* Abbreviations are explained in Table 1 ( see p.8 ) .

It is activated when the first (S1-S2) ≥ DTS & S1 ≥ MCT applies to all applications when the

elapsed time of the delay parameter CPD.

Enabling second when S1 ≤ FPC frost protection panels apply to all applications. The process

of opening and closing operation of R1 is a time (120 sec) by repeating S1> FPC.

Enabling third when S1 ≥ MTC overheat protection panels apply to all applications. The R1 will

be disabled when S1 <MTC at 3 ° C or HST = MTC.

Fault diagnosis:

The device V-DCS3 the time to be fed with electricity, check the status of the sensors continu-

ously. If any of the sensors has a problem or the cable is then cut on the screen shows the mes-

sage << Error >> next to the corresponding sensor (See page 6 example display 2).

CAUTION: For safety reasons, if a fault is detected in the collector sensor or sensors collectors

(application 4), the relay or relays (application 4) circulators will be activated and the relay R2

applications 2 and 3 will be disabled.
