FUNCTIONING
• ON/OFF:
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.
MAIN MENU
• FUNCTIONING Modality Selection
- Press P4 key to see the current modality: it’s signaled by the display and the led
- Pressing again the P4 key, you can select cyclically one of three functioning modality MAN, AUT , PRP signaled on the display and by
the specific led.
- The setting is automatically memorized after 4 seconds
- The L5 shows the status of the Fan
• SPEED Selection
- Pressing P2 or P3 keys the setting of the current fan speed is visualized or modified
- P0 = Off (only in Manual); P1 = Minimum Speed; P10 = Maximum Speed
- 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.
SECONDARY MENU
It allows to modify the functioning parameters of the controller.
- To enter the MENU push together buttons P2 and P3 for about 5 seconds.
- To scroll the code list use the button P2 or P3
- To show the parameter’s value push the button P4
- To modify the parameter’s value push the buttons P2 or P3
- To visualize again the code list and memorize push the button P4
- To exit and memorize wait for about 10 seconds.
The parameters are described in the following table
SECONDARY MENU PARAMETERS CODE MIN DEFAULT MAX
Temperature Fan Activation SET 30º 45º 99º
Temperature Fan Activation Hysteresis iSt 1º 2º 35º
ALARM Temperature Activation TAL 100º 120º 180º
