Individual CVE ECO 2 RFT ventilation systems can be
controlled either by a three speed hard wired switch or
by a wireless three speed RFT.
Radio frequency (RF) operation switch
The RFT (radio frequency) operation switch
(transmitter) can be used as a 3-position mode switch
with timer feature for the CVE ECO 2 RFT ventilation
unit. This operation switch can be used to set the
ventilation unit to one of the three ventilation modes
(capacities): The modes are:
•
Mode 1 - Low mode.
•
Mode 2 - Medium mode.
•
Mode 3 - High mode.
The low mode is used at night, the medium mode
during the day when there are people at home and the
high mode when cooking, showering or bathing.
The switch also has a timer. The ventilation unit can
be switched to high mode for a predetermined time
by pressing the timer button. The timer automatically
switches the ventilation unit to low mode after the time
has elapsed.
The length of time set for the timer is determined by the
user. Press the timer button once to set the ventilation
unit to high mode for 10 minutes. Press the timer
button twice to set the ventilation unit to high mode for
20 minutes. Press the timer button three times to
set the ventilation unit to high mode for 30 minutes.
If the operation switch is used by choosing mode 1, 2 or
3 while the timer is in operation, the timer is switched off
and the ventilation unit operates in the chosen mode.
