SETTING THE FAN SPEED
Depending upon type of ductwork, two types of speed settings can be chosen:
SETTING 1, for the fan kit with front or front/rear outlet with a short duct (factory setting for the series);
SETTING 2, for the fan kit with longer ductwork.
To change from one setting to another, after having turned on the fan in the AUTOMATIC or MANUAL mode, simply
press down on the "ON/OFF" and "-" buttons simultaneously (the acoustical signal in SETTING 2 consists of 2 beeps
followed by the beeps for the speed setting).
Again simultaneously pressing the "ON/OFF" and "-" buttons switches the system to the SETTING 1 mode (the
acoustical signal in SETTING 1 consists of 1 beep followed by the speed setting beeps).
Example:
if we are in SETTING 1 and at SPEED 3 and we hold the "ON/OFF" and "-" buttons pressed simultaneously to pass
to SETTING 2 we will initially hear 2 beeps which identify the new setting (SETTING 2) and then 3 beeps will be
heard which identify the speed setting (in this case SPEED 3).
To return to SETTING 1 simply press the "ON/OFF" and "-" buttons simultaneously again, in this case an initial beep will
be heard (SETTING 1) and then 3 beeps (SPEED 3).
Once having imposed the SETTING according to your type of ductwork, further modifi cations will not be needed.
When making the operating speed setting(V1 – V2 – V3 – V4), select the highest speed to bring the rooms to be heated to
the desired temperature; use lower speeds to maintain the temperature reached in the room.
SPEED 1
SPEED 2
SPEED 3
SPEED 4
NOTE: the layout indicates the voltage at which the unit operates, the airfl ow can vary depending upon the fi re box
and the type of ductwork.
IF THERE IS NO ELECTRICAL POWER
If electrical power is lost while in the AUTO mode, when power is restored, the fan will start at the speed it was at
before power was lost only if the probe detects a temperature greater than turn-on limit; should the temperature be
lower, the fan remains off and the unit shifts to the speed most recently set.
For the MANUAL mode also, upon restoring power, the fan will start at the speed most recently set.
