B-VENT GAS FIREPLACES (MPB33/35/40/45) • CARE AND OPERATION INSTRUCTIONS
OPTIONAL REMOTE CONTROL SYSTEM
The remote control system provides remote
ON/OFF burner operation.
The receiver (wall switch) accepts commands
from the handheld remote control transmitter
to turn the flame on and off.
Use the slider switch
(
Figure 20
)
to set the
receiver to one of three positions:
•
ON (manually turns on the burner)
•
REMOTE (remote ON/OFF burner control)
•
OFF (manually turns off the burner)
Receiver (Wall Switch) Functionality
The Receiver is powered by four (4) AA
batteries. The receiver accepts commands via
radio signal sent from the transmitter. When
the system is turned on, an acoustic signal
(“beep”) is generated to indicate that the
Receiver is ready to receive commands from
the remote control.
Remote Control Functionality
When the batteries are installed in the remote
control and the side slider is in the position
shown in Figure A, the LED on the transmitter
illuminates each time the ON/OFF button is
pressed.
Initializing the Remote Control System
To program the transmitter to the receiver,
slide the wall switch to the REMOTE position
(see
Figure 20
)
and press the ON/OFF key on
the handheld remote control.
The system has an automatic learning model
that allows the receiver to synchronize with a
new transmitter in the event the transmitter
must be replaced. As soon as the receiver
receives the first correct command from
any remote control, it will beep (3) times to
confirm synchronization.
Turning ON the Appliance
When the ON/OFF key is pressed
(
Figure 21
)
,
the LED on the transmitter illuminates and the
remote control is switched on.
Turning OFF the Appliance
If the appliance and the remote control are
switched on, when the ON/OFF key is pressed
(
Figure 21
)
, the Remote control is turned off.
The receiver beeps (2) times.
Low Battery Detection (Remote Control)
The life of the remote control batteries
depends on many factors, including battery
quality and number of appliance ignitions.
When the transmitter batteries are low, the
LED light will be dim to alert of a low battery
condition before losing all power. As soon
as the depleted batteries are replaced, the
Transmitter will restart its normal operation.
Low Battery Detection (Receiver Wall
Switch)
If the receiver batteries are low, a triple acoustic
signal will be emitted by the receiver when it
receives a command from the transmitter
depressing the ON/OFF key. This is an alert of
a low battery condition before losing battery
power at all. As soon as the depleted batteries
are replaced, the acoustic signal from the
receiver confirms the reception of the ON/OFF
command from the transmitter.
Child Safety Lockout
With this function it is possible to deactivate
the remote control key (see
Figure 21
)
.
Backup Function
If the batteries of the Receiver are low, the
appliance can be switched on manually by
moving the slider switch on the Receiver to
the ON position (see
Figure 20
)
.
