2.2 USING THE PLATINUM MAIN CONTROL (CONT’D)

DEHUMIDISTAT OVERRIDE SELECTION

In the operating modes MIN, MAX, 20 MIN/H and RECIRC, the user can select a

dehumidistat override so that if the relative humidity (RH) in the house exceeds the RH

setting previously stored, the ventilation unit will exchange in high speed until the

target indoor RH setting is reached.

An air exchanger is not a dehumidifier, but it can change the indoor relative humidity

by bringing in drier or more humid air from outside during non heating season. The

dehumidistat override function is useful to reduce indoor RH when the outdoor air is

cool and dry during the heating season. Select a target RH between 30% and 55%

according to your comfort. When outdoor relative humidity is high (e.g. in summer),

turn off the override by pressing OK until the RH display disappears.

When the dehumidistat override is activated, the AUTO indicator will

appear on LCD screen to show that the actual mode is being overridden.

Also, the relative humidity appears (if it was not shown, see example

beside). Once the target humidity level is reached, the unit goes back

into its original operating mode and AUTO disappears from LCD screen.

NOTE: If the actual mode is MAX, only the relative humidity level appears on

screen; AUTO label will not appear.

To engage the dehumidistat override, press OK. The actual indoor RH and the %HUM

label appear on LCD screen.

NOTE: If the actual RH is less than 20%, then the humidity indicator will display

“LO”, and if the actual RH is greater than 80%, then the humidity ndicator

will display “HI”.

To turn off the dehumidistat override, press OK again. The RH and %HUM display will

disappear from LCD screen.

POWER FAILURE

After a power failure, the wall control returns to its original operation mode. All settings

are kept in memory.

RESETTING MAINTENANCE INDICATOR: Press simultaneously on both arrow

buttons, Maintenance indicator will disappear from LCD screen.



AND

MAINTENANCE INDICATOR

The maintenance indicator is represented by an M in

a rounded triangle, at the top of the house (see

beside). If this indicator is flashing, perform the

semi-annual maintenance, and if it is not flashing,

perform the annual maintenance (refer to Section 3).
