COMMISSIONING

Check that all cable sizes, circuit breakers and wire connections are correct before following below commissioning
steps:
1. Switch-on / Switch-off: press the ON/OFF lkey to switch the unit on/off.
2. Match the correct speed to ERV: Press MODE for 6 seconds to enter parameters setting and at this time the parameter
number is shown in the middle of screen, press button SEt to parameter No.21 (refer to parameters list in comming page) then
press MODE shortly to enter the parameter setting, default value "0" blink at the top right corner, press UP and DOWN buttons to
charge the value according to below table (ERV code Vs Models) then press button SET again to confirm setting.
In the same way it is possible to set other parameters, always present in the table (Eg: parameter n ° 23 to value 2 = 10 DC Fan
Control speed).
3. Reading the temperature and fan speed probes: press the MODE key briefly to pass to OA (outside air), RA (return air),
SA (supply air) or EA (expelled air). In SA or RA mode, modify the air speed by pressing the ▲ and ▼ keys.
4. Bypass function for free cooling: the bypass is activated between 19°C and 21°C (OA temperature); press MODE if you
want to see the temperature. If the value measured is within this gap, the bypass will be activated automatically. If the OA
temperature is not within 19°-21° C, say 18° C, then press button MODE more than 6 seconds to enter the parameter setting.
Press SEt button to switch to parameter number 02, default value 19 flashes shown at the top right corner,Then press MODE
button shortly to enter setting, by pressing ▲ and ▼ buttons and set the value to be "X", "X" should be less than 18° C (present
OA temperature) then press SET again to confirm. With the same way to set parameter number 03 value to be "Y", if "X" < OA
temperature < "X+Y". Then bypass will open automatically, after bypass open, user can adjust the values under para-meters 2
and 3 to make OA<"X" or OA>"X+Y", then bypass will close automatically. Please pay attention that bypass open/closed will
be around 1 minute delayed.
