16. COMPLEMENTARY FUNCTIONS

16.1 Control of boiler anticondensing temperature

The anticondensing function prevents the formation of condensation in the boiler combustion

chamber. It imposes a decrease of 4 °C in the desired flow temperature for each °C decrease in the

actual return to boiler temperature (detector B4) in respect of the value set, thereby bringing about

the progressive closure of the regulating valve.

•

Anticondens : NO

= function disabled

YES

= function enabled

•

Desired T : - - .-

= minimum limit value of return to boiler temperature

If controller is in C-Ring the differential value is transmitted to all the controllers connected, so that

these are able to perform the anticondensing function with a single detector. The value of the

desired anticondensing temp. is that set on the controller to which the anticondensing detector is

connected.

2 Access keynumber

To enable the access keynumber enter the number (1900 ... 1999) using + and – keys.

The keynumber prevents use of + and - keys for changing data.

To cancel keynumber, press + and – at the same time until the dashes reappear.

When keynumber is enabled if + and – keys pressed on display appears

Only after having entered the exact keynumber can + and – keys be used.

If for 15 minutes no key is pressed the keynumber is automatically re-enabled.

16.3 Denomination zones

Entering names of primary and auxiliary zones which appear on relative pages of of programme

choices.

Using + and – keys, each dash can be replaced by a letter of the alphabet (A ... Z) or by a number

(0…9). The → key serves to position the cursor.

16.4 Display measurements

The controller displays all the measurements made by the detectors and the data useful for monitoring

the operational status of the zones.

• temperature

by current mode for primary control.

•

actual

temperature measured by detector B1 or B3.

Appears only if detector B2 is connected and configured.

• flow temperature

by primary control.

•

actual

flow temperature measured by detector B2.

Appears only if detector B5 is connected and configured.

• temperature

by current mode for auxiliary control.

•

temperature measured by detector B5.

Appears only if detector B4 is connected and configured.

•

5 Alarms

The controller is able to indicate, by means of the three LEDs situated on the facia, certain operational

disfunctions :

– fault in internal real time clock (LED 6.7)

– fault in C-Ring (led 6.

– fault in microprocessor (LED 6.
