3.8

Circulation units anti block control

The operating logic includes an anti block control of the circula-

tion units and mixing valves.

At the end of each heat request on a zone, a corresponding tim-

er lasting 24 hours is activated. If the timer expires, i.e. the cir-

cuit remains inactive, the following procedure is carried out:

−

Complete opening cycle of mixing valves (only for the low

temperature zones) for 120 seconds

−

Complete closing cycle of mixing valves (only for the low

temperature zones) for 120 seconds

−

Circulation units of all the zones powered for ten seconds.

At the end of the these operations, the timer starts again.

Each heat request by the REC, TA or CT interrupts the timer in the

zone concerned.

3.9

Anti-freeze control

The anti-freeze function protects the

BAG

from freezing with the

rooms being protected by the REC, TA or CT and the boiler pro-

tected by its own anti-freeze programme.

System sensors (12 and 13) are used to manage the anti-freeze

intervention threshold in the low temperature zones.

If the temperature detected by a sensor is less than 10°C, the

circulation unit of the zone concerned activates for 4 minutes to

recover the heat from the room. If the temperature rises above

the threshold of 10°C, irrespective of whether 4 minutes has

passed or not, the circulation unit switches off.

If after 4 minutes the temperature remains between 6 and 10°C,

the circulation unit remains off for 2 hours after which time it

will be reactivated for 4 minutes.

If the temperature should fall below 6°C at any time, a heat

request is activated for a heat equal to the system's minimum

temperature until the temperature detected by the sensor ex-

ceeds 10°C.

3.10

Night-time shift control

The "Night-time shift" function allows two delivery temperature

levels to be controlled.

On the zones, it is only possible to activate this function on the

Ambient Thermostat/Chrono-thermostat inputs and when there

is thermoregulation. If the contact on the TA / CT input of the zone

is closed, the delivery temperature is the one calculated by the

thermoregulation. If the contact is open, the delivery tempera-

ture calculated by the thermoregulation is appropriately correct-

ed in order for the ambient temperature to be balanced. In both

conditions, the circulation unit of the zone is always powered.

The "Night time shift" function is only to be activated on the

BAG

board by a quali

ed technician and only if absolutely

necessary.

The manufacturer declines all liability if parameter settings

are incorrect.

3.11

Setting the circulation units

The

BAG

is equipped with digitally controlled high ef

ciency

electronic circulation units. Below is a description of the main

characteristics and the procedures to be carried out in order to

set the required operation.

User interface

The user interface consists of a button (A), a two-colour LED red/

purple (B) and four yellow LED (C).

LED 1

LED 2

LED 3

LED 4

LED 5

The user interface allows the functions which are in operation

to be displayed (operating status, alarm status) and allows the

circulation unit operating mode to be set.

The performance data, indicated by the LED (B) and (C) is

always displayed during normal operation of the circulation

units while the parameters are set by pressing the button (A).

Indication of the operating status

When the circulation unit is operating, the LED (B) is green The

four yellow LEDs (C) indicate the consumption of electrical energy

(P1) as shown in the table below.

Indication of the alarm status

If the circulation unit has detected one or more than one alarm,

the two-colour LED (B) is red. The four yellow LEDs (C) indicate the

type of alarm as shown in the table below.
