The On/Off of the controller is made by pushing the button P1
The state OFF is signaled through the led L1
•
FUNCTIONING Modality
-
MANUAL
: advice signal
MAN
The fan is at the set speed independently by the Probe’s temperature
-
AUTOMATIC
: advice signal
AUT
The Fan starts at the set up speed when the trmperature is higher than the setted Thermostat
SET
-
PROPORTIONAL
: advice signal
PROP
The fan changes its speed according to the temperature in the range
SET ÷ SET+DEL
•
STANDBY Function
: if parameter
Stb =1
If the device is
OFF,
and the temperature is higher than the value of thermostat
TSI
-
The device goes in
ON
automatically
•
SAFETY
Function
: if the parameter
SIC = 1
If the probe’s temperature is higher than value of thermostat
TSI
And the fan is
OFF
in
MANUAL
Modality
-
The device goes automatically in the Proportional Modality waiting 10 seconds.
SAFETY FAN Function
: if the parameter
SAF = 1
If the probe’s temperature is higher than value of thermostat
TSA
-
The Fan is OFF
•
ALARM Function:
If probe’s temperature is higher than the value of thermostat
TAL
and the parameter
Enb = 1
-
The acoustic signal is activated
-
This signaling can be deactivated for 5 minutes by pushing a button
-
After 5 minutes, if there’s again the condition of alarm, it is activated again.

-
This function is not available in the PROPORTIONAL Modality
-
In the AUTOMATIC Modality the speeds that can be set are
P1 ÷ P10
FAILURE OR ALARM SIGNALS
The controller can signal the failure of the probe blinking message for the failure signal:
-
Lo
: indicates a low temperature (temperature under 0°C):
Probe Open or Disconnected
-
Hi
: indicates a high temperature (temperature over 180°C):
Probe in Short Circuit
ATTENTION
-
Avoid join together the probe’s cables with power’s cables.
-
Provide the system’s feeding with a bipolar switch according to the actual rules and with opening distance of the contacts of at least 3
mm for each pole.
-
Installation and the electrical connection of the device have to be made by experienced personal and with appropriate equipping.
-
Before the connection be aware that the electrical feeding is not connected.
