ELECTRICAL CONNECTIONS
The instruments are provided with screw terminal block to connect cables with a cross section up to
2,5 mm
2
for the digital and analogue inputs. Relays and power supply have a Faston connection
(6,3mm). Heat-resistant cables have to be used. Before connecting cables make sure the power
supply complies with the instrument’s requirements. Separate the probe cables from the power
supply cables, from the outputs and the power connections. Do not exceed the maximum current
allowed on each relay, in case of heavier loads use a suitable external relay.
N.B. Maximum current allowed for all the loads is 20A.
12.1
PROBE CONNECTION
The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid
infiltration. It is recommended to place the thermostat probe away from air streams to correctly
measure the average room temperature.

HOW TO USE THE HOT KEY
13.1
HOW TO PROGRAM A HOT KEY FROM THE INSTRUMENT (UPLOAD)
1.
Program one controller with the front keypad.
2.
When the controller is ON, insert the “Hot key” and push
o
key; the "uPL" message
appears followed a by flashing “End”
3.
Push “SET” key and the End will stop flashing.
4.
Turn OFF the instrument remove the “Hot Key”, then turn it ON again.
NOTE: the “Err” message is displayed for failed programming. In this case push again
o
key if you
want to restart the upload again or remove the “Hot key” to abort the operation.
13.2
HOW TO PROGRAM AN INSTRUMENT USING A HOT KEY
(DOWNLOAD)
1.
Turn OFF the instrument.
2.
Insert a programmed “Hot Key” into the 5 PIN receptacle and then turn the Controller ON.
3.
Automatically the parameter list of the “Hot Key” is downloaded into the Controller memory,
the “doL” message is blinking followed a by flashing “End”.
4.
After 10 seconds the instrument will restart working with the new parameters.
5.
Remove the “Hot Key”..
NOTE the message “Err” is displayed for failed programming. In this case turn the unit off and then
on if you want to restart the download again or remove the “Hot key” to abort the operation.

14.1
SILENCING BUZZER / ALARM RELAY OUTPUT
If “tbA = y”, the buzzer and the relay are is silenced by pressing any key.
If “tbA = n”, only the buzzer is silenced while the alarm relay is on until the alarm condition recovers.
14.2
ALARM RECOVERY
Probe alarms P1”, “P2”, “P3” and “P4” start some seconds after the fault in the related probe; they
automatically stop some seconds after the probe restarts normal operation. Check connections
before replacing the probe.
Temperature alarms “HA”, “LA” “HA2” and “LA2” automatically stop as soon as the temperature
returns to normal values.
Alarms “EA” and “CA” (with i1F=bAL) recover as soon as the digital input is disabled.
Alarm “CA” (with i1F=PAL) recovers only by switching off and on the instrument.
