3.2 Functional Description
Combustion
The combustion system consists of a fully modulating forced-draft combustion air blower(s), a negative
pressure regulated gas valve(s), and a premix burner(s). On a call for humidity, the blower is energized
to purge the system. During this time the control software performs diagnostic checks of the safety
systems – the air proving switch (not shown), the over-temperature switch and the external vent, as
well as the blowers. If the air proving switch is open, the warning message "AP Open Warn" appears, and
escalates to the fault message "AP Open Fault" if three consecutive warnings occur. At the same time, if
the over-temperature switch is open, the fault message "Over-Temperature Fault" appears. In addition, if any
of the blowers fail to operate during this time, the fault message "Blower Not Operating" appears. When the

13
Product OverviewCondair GS xxxxxxx_A_EN_1905_Condair-GS_OM
functions of the safety systems have been veried successfully, the gas valve(s) opens and the gas-
air mixture is pushed through the burner ports into the combustion chamber(s). The spark-igniter(s) is
simultaneously activated to ignite the gas-air mixture.
If a ame is not sensed by the ame sensor(s), the above sequence is repeated after 15 seconds. The
sequence is repeated upto a maximum of three times, after which the ignition control module(s) locks out
and the fault message "Ignition Fail" appears. If a ame is sensed by the ame sensor(s), the gas valve(s)
remains open and combustion continues. The gas valve(s) continues to maintain a constant air-to-gas
ratio independent of the blower speed or external conditions.
On the CS models, the hot ue gases pass through the primary heat-exchanger then the secondary
heat-exchanger, where it is cooled further before it exits through the exhaust vent. The heat recovered
by the secondary heat-exchanger is used to warm up the feed water. On the standard-e󰀩ciency model,
the hot ue gases pass through the primary heat-exchanger and exit through the exhaust vent.
Water Management
The humidier is equipped with a ll box and a oat chamber that monitors the water level in the tank.
The combination ll box is connected to the tank and to the oat chamber. The ll box is supplied with
water from the water supply, and from the secondary heat exchanger in CS models. A vacuum break
valve is used tprevent siphoning in the drain connection.
In the CS model, a secondary heat-exchanger promotes higher e󰀩cencies. This is achieved by using
the heat from the exhaust to pre-heat the cold ll water entering the ll box. Water from the ll box then
enters the bottom of the tank.
The oat chamber is connected to the top and bottom of the tank to monitor water levels with reference
to the low operational pressure inside the tank. The oat chamber and its control board consists of two
magnetic oats (one is a backup) that measure the water level. These levels correspond to 3 LEDs on
a display panel and are monitored by the control software.
Water Levels:
L5 (yellow LED) — high water level
L4 (green and yellow LED) — intermediate water level
L3 (green LED) — middle water level
L2 (green and red LED) — intermediate water level
L1 (red LED) — low water level
On initial start-up, the dual ll valves ll the tank and the oat chamber. A start-up test monitors the water
level as the tank and oat chamber lls, and ensures proper functioning of the unit.
Note: A fault message "Float Level" may appear at any time. This indicates an invalid combination of
readings from the control software (for example, if L5 and L1 LEDs activate at the same time).
1. The water level reaches the backup oat, then the main oat.
2. As water lls the oat chamber and reaches the L1 level, the control software performs a test to
verify proper functioning of the dual ll valves and the drain pump.
a. Water enters the oat chamber via the tank. The ll valves will allow water to ll the tank and
raise the water level in the oat chamber to L5.
b. The drain pump energizes to lower the water level to just below L3.
Note: The water levels should appear in ascending then descending order; L1, L2, L3, L4, L5, L4,
L3. A fault message "Fill Check Fault" appears if the water level does not rise to level L5. A fault
message "Drain Check" appears if the water lvel does not drop below the level L3.
3. When the test is complete, the dual ll valves activate and the water level should rise to level L3.
4. If a demand signal is present, the humidier begins the combustion sequence.
5. The drain pump and dual ll valves maintain the water level between levels L2 and L5.

14 Product Overview Condair GSxxxxxxx_A_EN_1905_Condair-GS_OM
If Float Check is enabled during steam production, the control software will activate the drain sequence
every 24 hours (adjustable to any time of day) to verify proper functioning of the oats, dual ll valves,
and the drain pump.

Table 4: Status Icon Descriptions
Icon Description
The icon appears to the left of the operating status message or the maintenance/fault message when
the system is working normally.
Warning
The icon appears to the left of the maintenance/fault status message when a maintenance reminder
or a condition with a "Warning" status is active. The humidier will continue to produce steam when
there is a demand (unless the warning relates to a control signal).
A condition with a "Warning" status is active. Typically, these conditions are of a temporary nature,
or conditions that cannot cause damage to the system. Depending on the condition, the Condair GS
humidier may be stopped or remains operable (unless the warning relates to a control signal). If the
cause of the condition clears on its own accord, the warning message is automatically reset. If the
condition becomes worse, a fault message may be triggered.
When a warning message is active, the status LED turns yellow in color.
Fault
The icon shown appears to the left of the maintenance/fault status message when a condition with a
"Fault" status is active. The humidier stops producing steam.
A condition with a "Fault" status is active. Typically, these are conditions which prevent further opera-
tion of the humidier, or conditions that can cause damage to the system. When a fault condition
occurs, the Condair GS humidier stops steam production immediately.
When a fault message is active, the status LED turns red in color.
4.2.3 Maintenance and Fault Status
The Service/Warning/Fault status area of the Home screen (refer to Table 5 on page 17) shows mainte-
nance reminders, warning and fault status messages along with associated status icons. This eld also
allows access to the "Service Menu". When a maintenance reminder, warning or fault status message is
active, the list of current faults/warnings can be accessed directly from this eld to view additional details.
The general maintenance reminders and alarm messages displayed in this area are described in Table 5,
and the status icons are described in Table 4. Refer to ""Warning and Fault List" on page 60 .
Table 5: Maintenance/Fault Status Descriptions
Message Description
Service info No faults conditions present.
Maint. Warning This maintenance reminder appears when the Service Interval time set in the control software
has elapsed. The unit can continue to operate for another 200 hours, after which a corre-
sponding fault message appears and the unit stops operating.
Perform the required scheduled maintenance, then reset the service reminder in the Service
menu. Refer to "Maintenance Procedures" on page 50.
Warning A condition with a "Warning" status is active. Depending on the warning condition, the hu-
midier will continue to produce steam when there is a demand (unless the warning relates
to a control signal).
In addition, the status LED turns yellow in colour.
Fault A condition with a "Fault" status is active. Depending on the fault condition, the humidier will
not produce steam until the fault condition is cleared.
In addition, the status LED turns red in colour.
