SEQUENCE OF NORMAL OPERATION - HEAT MODE
1. When heat is required, the thermostat closes and energizes the combustion
air motor.
2. As the blower reaches approximately 90% of the normal RPM, the pressure
created by the combustion air motor causes the diaphragm in the pressure
switch to move, closing the contacts. This completes the electrical circuit to
the input of the module board and a 10 second warm-up period for the glo-
bar is established. During the warm up period, the glo-bar comes on for 7
seconds, then the valve opens. The glo-bar remains on another 3 seconds
after the valve opens and then goes off. When the valve opens, it will remain
open for 6 seconds. Gas will flow to the burner and be ignited by the glo-bar.
3. If the main burner flame is sensed, the burner will remain on until the
thermostat is satisfied. If the flame is not sensed, the gas valve closes and
the ignition sequence automatically repeated two (2) times. If the burner does
not light during this trial for ignition period, the unit will lock-out for one (1) hour
and then re-set automatically.
NOTE: If lock-out should occur, the unit can be re-set manually by breaking
the power to the unit. When power is restored, the ignition procedures can be
repeated. Should repeated lock-out occur, shut unit down and contact your gas
service agency.
4. After proof of ignition (burner lights and flame properly sensed) a circuit is
completed to the room air blower and the blower comes on.
5. When the thermostat is satisfied, the valve closes. The combustion air motor
will remain on for a 20 second purge cycle, then goes off. The room air blower
will continue to operate for approximately 90 seconds at which time the circuit
is opened and the room air blower goes off.
NOTE: If your unit is controlled by a wall thermostat, the ignition sequence is the
same as with built-in thermostat; however, the temperature setting and system
functions are selected at the wall thermostat. The "Fan" speed is controlled in the
same manner as with built-in thermostat.
B. COOLING MODE - Normal Operation (See Figure 11)
1. Depress "System" key pad until cool lamp is illuminated.
2. Depress "Fan" key pad until desired speed lamp is illuminated.
3. Set thermostat to desired setting by depressing temperature indicating arrows
until desired temperature is displayed.
4. If the thermostat circuit is closed at the setting chosen in Step 3, the cooling
cycle begins. NOTE: On initial start-up, the compressor will not be energized
for five (5) minutes even though the system functions have been properly
selected.
Whenever the outside temperature is below 65° and the humidity is high, frost
could form on the evaporator coil during extended cooling operation. To eliminate
frost formation, a de-ice switch in the compressor circuit will sense a frost
condition and open the compressor circuit. Upon temperature rise, the switch
will close and the compressor will again come on provided the thermostat is still
calling for cooling.
NOTE: This unit has a built-in 5 minute delay between compressor cycles. Any
time the compressor cycle is interrupted either manually, through thermostat, a
power interruption, etc., the compressor will not restart for 5 minutes.
C. OPTIONAL CARBON MONOXIDE (CO) DETECTOR (See Figure 25)
This Dynaline unit may be equipped with an integrated carbon monoxide (CO)
detector (System Sensor Model C01224T). To access the CO detector remove the
DL front. The CO detector is located on the left side of the unit and consists of the
detector and a power supply board. See figure 25. The system connected carbon
monoxide detector known as CO1224T was tested at a National Recognized Test
Laboratory and has been verified to perform in the detection of carbon monoxide
up to 12,000 ft above sea level. During this testing by the National Recognized
Test Laboratory the detector alarmed within the time specified by ANSI/UL 2034
for carbon monoxide concentrations of 70, 150 and 400 parts per million (ppm).

Alarm Test: Will send alarm signal to panel.
Hush feature / Alarm Silence: The audible alarm can be silenced for 5 minutes
by pushing the button marked "Test/Hush". The red alarm light will continue to
flash in temp 4 pattern. If carbon monoxide is still present after the 5 minute hush
period, the audible alarm will sound. The hush feature will not operate at levels
above 350 ppm carbon monoxide.
Trouble Feature: When the sensor supervision is in a trouble condition (e.g. such
as a sensor that has been tampered with, or the cell itself has prematurely dried
out due to environmental conditions, etc.), the detector will send a trouble signal
to the panel. The detector must then be replaced. The green LED turns off and
the red LED blinks every minute when the detector is in trouble.

End of Life Timer Feature: When the detector has reached the end of its life, the
trouble contact will open. This indicates that the CO sensor inside the detector
has passed the end of its life and must be replaced. This detector's lifespan is
approximately six years from the date of manufacture. The green LED turns off
when the detector is in trouble. Periodically check the "Replace by" sticker located
under the detector cover. The detector must be replaced by this date. Order a
replacement CO Detector number 233207 from the installer of the PTAC or the
selling dealer.
CAUTION: Airborne dust particles can enter the detector. Suburban recommends
the installation of Dynaline units with System Sensor carbon monoxide detectors
after construction or any other dust producing activity.
TESTING
Detector must be tested after installation.
Test the detector as follows:
1. A test button is located on the detector housing (see Figure 25).
2. Use the tip of your finger to press and hold the test button.
3. If the sounder beeps and the LEDs light up after 1-4 seconds, the detector is
operational.
If detector fails the above test method, its wiring should be checked. If the detector
still fails after rewiring, it should be replaced.
Resetting the CO detector:
This Dynaline unit with integrated CO detector is equipped with a manual reset
button located at the plate immediately to the left of the CO detector. The manual
reset button is identified by a label on the plate. When the test/ hush button
on the CO detector is depressed the detector will audibly alarm, the green LED
will extinguish and the red LED will flash. Power to the DL gas valve will be
interrupted and the gas valve will close.
detector, it will be necessary to depress the manual reset button to reset the CO
detector and allow the DL unit to reopen the gas valve circuit.
What to do if the carbon monoxide detector goes into alarm:
Should the CO detector go into alarm mode due to the detection of CO the power
to the gas valve will be interrupted and the gas valve will close. Do not ignore the
alarm and shutdown. Immediately move to a spot where fresh air is available,
preferably outdoors. Find a phone in an area where the air is safe and call your
building manager and ask them to have the Dynaline unit and/or other fuel burning
appliances in the dwelling checked for proper operation. Do not return to a room
or dwelling where the CO detector continues to alarm. After the cause of the
alarm is determined and corrected, it will be necessary to depress the manual
reset button to reset the CO detector and allow the DL unit to reopen the gas
valve circuit.
DETECTOR REPLACEMENT
WARNING!
Remove Power before replacing detector.
This detector is manufactured with a long-life carbon monoxide sensor. Over time
the sensor will lose sensitivity, and will need to be replaced with a new System
Sensor carbon monoxide detector. This detector's lifespan is approximately six
years from date of manufacture. Periodically check the detector's replacement
date.
Using a small, flat screw driver, push in the small tab located on the
underside of the detector. Once the snap is loosened, lift the bottom end of the
cover up and unhinge the top to remove the cover. With the cover removed
removed, refer to the sticker placed on the inside of the detector. The sticker
will indicate the date that the detector shall be replaced.
equipped with a feature that will open the trouble relay once it has reached the
end of its useful life. If this occurs, it is time to replace the detector.
CAUTION: This carbon monoxide detector is designed for indoor use only. Do
not expose to rain or moisture. Do not knock or drop the detector. Do not open
or tamper with the detector as this could cause malfunction. The detector will not
protect against the risk of carbon monoxide poisoning if not properly wired. The
detector will only indicate the presence of carbon monoxide gas at the sensor.
Carbon monoxide gas may be present in other areas.
This carbon monoxide detector is NOT:
• Designed to detect smoke, fire or any gas other than carbon monoxide
• To be seen as a substitute for the proper servicing of fuel-burning appliance or
the sweeping of chimneys
• To be used on an intermittent basis, or as a portable alarm for the spillage of
combustion products from fuel-burning appliances or chimneys.
Carbon monoxide gas is a highly poisonous gas which is released when fuels are
burnt. It is invisible, has no smell and is therefore impossible to detect with the
human senses. Under normal conditions in a room where fuel burning appliances
are well maintained and correctly ventilated, the amount of carbon monoxide
released into the room by appliances should not be dangerous.
