5.8.2 External alarm from digital input

The instrument can signal an alarm external to the instrument using the digital input setting iFi = 4 or 5. The instrument signals the alarm turning ON the alarm LED ( ) and displaying AL label alternated to the variable set with parameter Ids.

Mode iFi = 4 operates no action on the control output, while iFi = 5 deactivates the control output at digital input intervention.

5.8.3 Open door alarm

The instrument can signal the open door alarm coondition using the digital input setting iFi = 1, 2 and 3. As the Digital input is activated, the instrument signals that the door is open showing on the display the

oP label alternated to the variable set with parameter ids.

After the delay set with parameter AoA the instrument signals the Open Door alarm with the configured devices

(buzzer and/or Output), lighting up the LED while showing the

oP label. At the open door alarm intervention are also re-activated the inhibited outputs (compressor).

5.9 Function of keys and

Two of the instrument keys, in addition to their normal functions, can be configured to operate other commands. The key function can be defined using the tUF parameter while the key via parameter TFb. Both parameters have the same possibilities and can be configured to perform the following functions:

oF The key carries out no function;

1. Do not use;

2. Pressing the key for at least 1 s, you can sequentially select a

normal or eco operating mode (SP/SPE).

A selection has been made the display shows for about

1 s the active set point code (SP or SPE);

3. Pressing the key for at least 1 s is possible to switch the instrument from

ON to Stand-by state and vice-versa;

4. Do not use.

5.10 Parameters configuration by “A01”

The instrument is equipped with a connector that allows the transfer from and toward the instrument of the functioning parameters through the device A01 with 5 poles connector.

This device it is mainly usable for the serial programming of some instruments which need to have the same parameters configuration or to keep a copy of the parameters setting of an instrument and allow its rapid retransmission.

The same device allows to connect a PC via USB with which, through the appropriate configuration software for “AT UniversalConf tools”, the operating parameters can be configured.

To use the device A01 it is necessary that the device or instrument are being supplied directly or through the key.
