MAIN SETTINGS (Run Mode)

VENTILATION TEMPERATURE SETTING.

Press °C VENT:
This messagge will be displayed instead of the °Set
Ventilation temperature value (start first speed).
Press + or - to modify, press °C VENT to confirm.

MINIMUM SPEED SETTING.

Press MIN VENT:
This messagge will be displayed instead of the Minimum

Ventilation Speed.

Press + or - to modify, press MIN to confirm.

MAXIMUM SPEED SETTING.

Press MAX VENT:
This messagge will be displayed instead of the Maximum
Ventilation Speed.
Press + or - to modify, press MAX to confirm.

In normal condition ambient temperature is displayed and in setting coindition flashing
messagge appear.
The normal condition become again after exit from setting mode (auto-exit is performed
after 5 seconds from last key stroke in setting condition).

AMBIENT TEMPERATURE VIEWING

Press + : will be displayed followed by

°Maximum Temperature Recording.

Press - : will be displayed followed by

°Minimum Temperature Recording.

VIEWING TEMPERATURE RECORDING

Values recorder are memory permanent stored: for memory clear keep pushed + keys
for more than 3 seconds: CLEA messagge will be composed on display before clearing
operation.

How to connect the line
Connect line on terminals L-N; protect supply with adeguate fuse.

How to connect the sensors

Connect the temperature probe provided as shown in the diagram. For remote
connections use a standard 0.5-square millimeter two-pole wire for each sensor,
taking great care over the connections, by insulating and sealing the joins carefully.

How to connect the contacts

Connect terminals 3-7 / ...11-13 on the terminal block (contacts up to 4AMP.AC1).
Output contacts are N.O. (Normally Opened and free of voltage) on wich is aplliable a
4AMP AC1 maximum load.
3-4= Speed 1 contact.
3-5= Speed 2 contact.
3-6= Speed 3 contatc.
3-7= Speed 4 contact.
11-12= Heat contact.
12-13= Cool contact.

These settings refer to the mode of operation of the system and must be
made on initial start-up. Press - / + together for at least one second.
the message C.O.S.t. will be displayed.
Press than repeatly MAX VENT until interested variable's message is
displayed (see table below) : variable value and related messagge will be
displayed.
Press + or - to set a new value and then MAX VENT to confirm.
The next system constant will then appear. You can press MAX VENT for a
least two second to escape and return to the Run Mode.

COSt PROGRAMMING (System constants)

"HAND MODE"

In some start-up conditions may be useful to work in "hand" mode.
Power off theprocessor, press + key and keep it pressed giving power on:
HAnd messagge will be displayed (release now + key).
Push + until is displayed number required to be handed (see table relays

"N° Relay") and push MAX VENT for activing relay.
Pushing again + for increase relay number previous relay is disactivated. You can
press MAX VENT for a least two seconds to escape and return to the Run Mode.

*2) This set is a relative set reffered to temperature setted on°C VENT key.

For example if is setted °C VENT=25.0° and r.HEA=-0.5° heating command (HEAT)
will start at 24.5° (25.0°-0.5°).
Heating will be OFF after 0.2° (value d.HEA).

*3) tEnP =0 : °C Temperature range.

tEnP =1 : °F Temperature range.

*4) You can correct the readings on the sensor (+ or -).
*5) Four different mode of ventilator initial start-up optionally settable (step from 0 to 1

speed).

tYPE=1 : 0 to 1 step become in normal mode.
tYPE=2 : 0 to 1 step become with a momentary 10 seconds at speed 2.
tYPE=3 : 0 to 1 step become with a momentary 5 seconds at speed 3.
tYPE=4 : 0 to 1 step become with a momentary 5 seconds at speed 4.
Options 2, 3 , 4 permits to make an easy opening of shutter models ventilators.
