LEDS
“ON” - LED ON - Unit ON
LED OFF - Unit OFF
“READY”- BLINKING LED - Unit initialization.
The display will count down the minutes until unit is ready.
During count down the right digit will flash.
The unit initialization occurs only the first time it is powered by
technician (connected to 24VAC line).
LED ON - Unit active.
JUMPERS
JP1 - Right pos. (24V) - Factory use only (always in right position)
JP2 - OPEN - Factory use only (always OPEN)
JP3 - OPEN - Converter configuration (see graph)
SHORT - Controller configuration (see graph)
JP4 - OPEN - Unit initialization time enabled (Default)
SHORT - Cancel 20 minutes initialization time.
Note: The sensor’s measurements are not accurate during the
20 minutes required for initialization.
JP5 - Left pos. (3) - Factory use only (always in left position)
CP1 - OPEN - Factory use only (always OPEN)
CP2 - OPEN - Factory use only (always OPEN)
INTERNAL TRIMMERS
All trimmers are for FACTORY CALIBRATION ONLY and should not be touched !
ON–OFF BUTTON
Use the ON–OFF button to turn the unit ON or OFF
When ON, the green LED “ON” will turn ON.
SET-POINT TRIMMER
Use the SET POINT trimmer to define the required level of air quality (range 1...98).
1 = DEMAND FOR CLEAN AIR, 98 = DEMAND FOR POLLUTED AIR
Special set point values (regardless of measurements):
0 = OUTPUTS FULLY OPEN, 99 = OUTPUTS FULLY CLOSE
ENVIRONMENTAL CONDITIONS
Operating temperature 0°C to 50°C
Storage temperature -20°C to 70°C
Relative humidity Less than 95% RH
Oxygen (O2) concentration 21% ± 1% (Absolute minimum level: more than 18%)
