DVA4136 Series Direct Vent Gas Fireplace
10010270
Main Flame Modulation
The main flame modulation will use the step motor on
the main gas valve.
The control of the main flame level will be from a button
on the handheld transmitter. When the FLAME MAIN
button is pressed, the main flame setting level will flash
on the LCD display and the user can select desired
setting from highest to lowest with 6 different levels via
the UP and DOWN buttons. If no adjustment is made
within 7 seconds, the control will exit the function setting
mode and the LCD display will return to the normal
view.
To allow for proper burner ignition the main flame will
come on to the number 7 level, or the highest. After
5 seconds that system will turn the flame level to the
last position before turning off. This will have to be
in all modes of the operation,
Manual, Thermo, and
Program.
Rear Flame Modulation
We are looking to control a second burner separately
from the main burner. The control will use our step
motor with a block valve that would have 4 levels from
high to completely off.
The control of the main flame level will be from a button
on the handheld transmitter. When the FLAME REAR
button is pressed, the rear flame setting level will flash
on the LCD display and the user can select desired
setting from highest to lowest with 4 different levels via
the UP and DOWN buttons. If no adjustment is made
within 7 seconds, the control will exit the function setting
mode and the LCD display will return to the normal
view.
To allow for proper burner ignition the rear flame will
come on to setting level 3, or the highest. After 5
seconds that system will turn the flame level to the
last position before turning off. This will have to be
in all modes of the operation,
Manual, Thermo, and
Program.
Countdown Timer
The timer function is like the 1001LCD in that you will
have up to 3 hours of countdown time for the fireplace
to run and can be operated in both Manual and Thermal
modes.
Once you have pressed the timer button the "TIMER"
name under the clock will start to flash at 10 minutes
as the start point. The user can change the time from
10 minutes to 180 minutes, 10 minutes segments. If no
adjustment is made within 7 seconds, the control will
accept the 10 minute setting, exit the function setting
mode, and the LCD display will return to the normal
view.
• Pushing "TIMER" button, you can set the flashing
clock with the "TIMER" under the clock area.
• You can press the "up" or the "down" to set your
desired TIMER segment.
• Once the timer is set to the desired number of
minutes the number will flash for another 7 seconds
and then go into the timer setting and start to count
down.
• The user can press the "SET" button and the system
will immediately start the TIMER function.
• If the "TIMER" button is pressed again while
the timer is counting down the "TIMER" will be
terminated.
• If the OFF mode is activated the "TIMER" will be
terminated. OFF is OFF in all cases.
Thermo Mode
Selection of the THERMO or Thermostat mode with
the MODE button will light the smaller SET window of
numbers. The first SET number will be 45° F, and with
UP or DOWN keys you can SET the temperature that
the user would like the room to maintain.
Once the SET temperature is correct, within 5
seconds of time, the appliance will operate to that Set
Temperature.
The flame ICON and ON & THERMO will be on the
LCD screen. At this point the appliance will be burning.
The user will not have to operate the "SET" button to
set the temperature. But if the SET button is pushed, it
also completes the process for setting temperature.
You can use DOWN or UP buttons to obtain a new
desired temperature. Simply use the UP and Down
buttons to set the new temperature and the appliance,
within 5 seconds, will turn ON or OFF and will still show
THERMO on the LCD screen
Another short push of this MODE button will cancel the
THERMO function. In another words, a short push of
MODE button will de-activate THERMO function, and
the appliance will be OFF.
The new CFM control will have an additional feature to
the thermostat control with flame modulation as the set
temperature is obtained.
The outline of the turn down will be based on the
degrees under the setting temperature. The coding will
be like the following.
Set Temperature will be from 45° F to 99° F
The flame modulation will have six levels from highest
to lowest on the main fireplace burner, that is controlled
with a step motor on the gas valve. The rear burner will
be control separately with another set of wires coming
that same module. Another step motor and block valve
will be used to operation this separate rear burner
within this system.
