1
Access keynumber
Choice and enabling of access keynumber which prevents the use of + and – keys and thereby any
modification of the data. Enter the number (1900 … 1999) using + and – keys.
To cancel keynumber press + and – at the same time until the dashes re-appear.
When the keynumber is enabled, if you press + or – keys there will appear on the display the request
to enter the keynumber.
Only after having entered the keynumber correctly can you use + and – keys.If for 15 minutes no key
is pressed the keynumber is re-enabled automatically.

Name of plant site
Entering name of site which appears on first page of display.
Using + and – keys, each dash can be replaced by a letter of the alphabet (A…Z) or by number
(0…9). The
←
and
→
keys serve to position the cursor..

Display measurements
The controller displays all the values measured by the detectors and the data that serves to monitor
the operation of the plant. If the detectors are not connected or are damaged - - - - will appear.
• Actual outside temperature.
• Boiler temperature desired by current mode and actual measured by B4 detector.
• temperature boiler flue gases measured by detector B7.
• Maximum temperature flue gases measured by B7 detector after last re-set.
To cancel the recording press + and – keys at the same time.

Anticondensing function
When the boiler temperature (B4 sensor) falls, in respect of the desired value, by three times the
differential set, the controller creates a value for Anticondensing equal to [ (BT desired – 3dBT)
– actual BT] x 2 and sends it to C-Ring. The Anticondensing value is used by the heating controllers,
connected in C-Ring, and with the Anticondensing function enabled, in order to lower their desired
flow temperature so as to allow the boiler to recover more rapidly..
