In alarm conditions with “i.Fi”= 9 all the control outputs will be off.
4.10.3 - OPEN DOOR ALARM
The instrument can signal an open door alarm by activating the
digital input with the function programmed as “i.Fi” = 5 or 6.
When the digital input is activated the instrument show
oP
and
after the delay programmed in parameter
“A.oA”,
the instrument
signals the alarm via the activation of the configured alarm output
(buzzer/ouput).
At the intervention of the open door alarm the inhibited output will
reactivated (fans or fans + compressor).
4.11 - FUNCTIONING OF KEYS “U” AND “DOWN/AUX”
Two of the instrument keys, in addition to their normal functions,
can be configured to operate other commands.
The U key function can be defined by the parameter
“t.UF”
while
the DOWN/AUX key function can be defined by the parameter
“t.Fb”
Both the parameters have the same possibilities and can be
configured for the following functions:
=oF
- The key carries out no function.
= 1
- Pressing the key for at least 1 second, it is possible to
enable/disable the auxiliary output if configured (“o.Fo”=2).
= 2
- Pressing the key for at least 1 second, it is possible to
enable/disable a continuous cycle.
= 3
- Pressing the key for at least 1 second, it is possible to select
one of the 2 memorised set point in rotation. Once selection has
been made, the display will flash the active set point code for about
1 sec. (SP, SP2).
= 4
- Pressing the key for at least 1 second, it is possible to switch
the instrument from the ON status to Stand-by status and vice
versa.
4.12 - ACCESSORIES
The instrument is equipped with a connector that allows the
connection of some accessories described as follow.
4.12.1 - PARAMETERS CONFIGURATION BY “A01”
It is possible the transfer from and toward the instrument of the
functioning parameters through the device
A01
with 5 poles
connector.
This device A01 it’s mainly useable for the serial programming of
the instruments which need to have the same parameters
configuration or to keep a copy of the programming of an
instrument and allow its rapid retransmission.
The same device can connect the instrument via USB to a PC and
through the proper configuration software tools "TECNOLOGIC
UniversalConf”, it’s possible to configure the operating parameters.
To use the device A01 it’s necessary that the device or instrument
are being supplied.

4.12.2 - “TVRY” REMOTE DISPLAY
To the instrument it is possible to connect the remote display
TVR
Y
through the special cable that can have a maximum length of 10
m. The device TVR Y, directly supplied by the instrument, it allows
to visualize the temperature measured by the probe Pr1 through a
2 ½ digit display.

cable 10 m MAX.
For additional info, please have a look at the TVR Y instruction
manual.
4.12.3 - RS 485 SERIAL INTERFACE BY “TLCNV”
The instrument can be connected by a special cable to the
TLCNV
device (mod. C - TTL/RS485 interface), by means of which it is
possible to connect the regulator with a net to which other
instruments (regulators of PLC) are connected, all depending
typically on a personal computer used as plant supervisor.
Using a personal computer it is possible to acquire all the function
information and to program all the instrument’s configuration
parameters.
The software protocol adopted for the instrument is a MODBUS
RTU type, widely used in several PLC and supervision programs
available on the market (Y and Z series protocol manual is
available on request).
If the instrument is used with TLCNV program by the parameter
"t.Ad"
the station Address.
Set a different number for each station, from 1 to 255.
Note:
The baud-rate are fixed at 9600 baud.
TLCNV interface is directly supplied by the instrument.
