8Product Overview Condair TE
3 Product Overview
The Condair Ceiling Mounted Evaporative Humidier is a ceiling-embedded cassette humidier that directly
humidies the room. Each unit is installed inside the ceiling (or in an open ceiling) with a decorative cover
that can be opened and closed easily for maintenance. Each unit operates independently and provides
reliable performance that is not a󰀨ected by the system settings of the air conditioner (temperature, air
ow, etc.).
Figure 1: Components
3.1 Functional Description
Supply water passes through the supply header and is dripped evenly across the Humidication module.
Water drips downward through the media. Supplied air passes through the cassette where it evaporates
water on the surface of the media to create humidied air. Water that has not evaporated continues to
ow down the media where it picks up any dust and other debris, and drips onto the drain pan.
Figure 2: Functional Description
When operation is initiated via pressing of the operation button or an external command signal input,
when the humidistat is turned ON, and in other such situations, the fan will remain OFF at the start of
humidication operations and water will be continuously supplied to wet the humidication module which
washes away odour-causing elements and similar brought in via the supply water. This initial supply
water intake process lasts for 10 minutes.
After initial supply water intake, the unit will switch to intermittent water supply (time sharing system, or
TSS), the fan will begin operating and humidication will start.

Product OverviewCondair TE
When operation is ceased via pressing of the operation button, an OFF external command signal input,
or similar, water supply will be stopped and only the fan will continue operating. After the humidication
module has been dried by the fan in this manner, the unit will automatically shut o󰀨.
Drying operation of the humidication module takes approximately 2 hours. Generally, the drying process
activates for 2 hours after the unit stops humidifying. However; if the humidier operates continuously
for 24 hours without a 2-hour drying period, the drying process will activate automatically.
3.1.1 Remote Controller
The humidier must be used with the remote controller. The remote controller contains a humidistat, and
is used to control up to ten units at once. For more information on the remote controller and how to use
it to humidify the space, refer to “Operator Interface” on page 10.

5 Operation
PersonnelQualications
The humidier must only be operated by personnel who are adequately qualied, well trained and are
authorized by the customer.
Safety
Certain operations of the unit may require the user to access the control cabinet or plumbing cabinet,
which may expose the user and equipment to the hazards described in chapter 2 on page 5.
5.1 TurningONtheHumidier
Important! Following the start of humidier operation, continuous water supply with no fan operation
is carried out for 10 minutes to wet and clean the humidication module, after which intermittent water
supply and fan operation begins.
When restarting the humidier after a long-term shut-down, carry out the maintenance procedures and
checks described in “Maintenance” on page 21.
To turn ON the humidier:
1. Press the Power button on the remote controller. The water supply will turn on for 10 minutes while
the fan will remain o󰀨. After 10 minutes, fans will activate.
5.2 TurningOFFtheHumidier
Upon stopping operation (via remote controller), the Humidier will turn on the fan to dry the media inside
the unit. Note that turning o󰀨 the humidier does not stop power from owing through it. Remove the
power source before performing any maintenance.
For long term shut down, refer to “Decommissioning” on page 34.
To turn OFF the humidier:
1. Press the Power button on the remote controller. The unit will stop humidifying (solenoid valve closed)
and after a brief delay (standby), the fans will activate for 2 hours before deactivating.
5.3 FindingtheHumidierthatActivatedanAlarm
Any alarms present in the humidier group will be indicated on the remote controller. Humidiers with
an alarm will make beeping noises (via instructions below) to indicate that it is the unit with the problem.
To nd the problematic humidier:
1. Press the FIND button on the remote control. The humidier (that is sending the alarm signal) will
beep for 30 seconds.
2. Once the humidier is found, press the FIND button again to stop the beeping.

14 Operation Condair TE
5.4 TurntheFanHigh/Low
The fan in the humidier runs on two speeds, high and low.
To toggle the fan speed between high and low:
1. Press the Fan button on the remote controller. Toggle this as necessary while the product is operating.
5.5 Turning OFF the Fan
The fan activates periodically during 24 hour operation of the humidier, as well as after humidier shut
down, to dry the media in the humidier. Drying improves hygienic operating conditions, so it is strongly
advised to AVOID SHUTTING OFF THE FAN prematurely and allow the humidier to dry properly.
To turn o󰀨 the fan:
1. Press the Stop button on the remote controller.
5.6 ConguringtheHumidier
5.6.1 Increasing/DecreasingtheWaterSupplyVolume(DIPSwitchSettings)
The solenoid valve opens and closes to allow water to periodically enter the humidication module. The
ratio between ON and OFF will depend on the water quality and the DIP switch setting DS1.
Your water supply may contain minerals, such as calcium and magnesium, and the air may contain
dust and other debris. If there is a large quantity of contaminants in the air and water, it is important that
they are washed away more frequently. Thus, the Condair Ceiling Mounted Evaporative Humidier will
require extra supply water volumes to do this.
Another reason one would want to increase the water supply volume would be because the air intake is
dry, such as during the heating season. With an increase in dry air, the formation of scale is increased,
so increasing the water supply volume can help alleviate this.
To change the water supply volume:
1. Remove power to the humidier. Failure to do so will prevent the settings from saving on the unit.
2. Adjust the DIP Switch DS1 settings on the humidier. Refer to Table 4 on page 14. The DIP switch
can be found on the control unit (refer to Figure 5 on page 12).
After changing the water volume settings, water supply should remain open for 10 minutes before
entering normal operation.

OperationCondair TE
5.6.2 Enabling Interlocking Operation with External Equipment
This setting allows operation with external equipment, such as an air conditioner. Ensure that the humidier
has been set up for use with the remote controller with built-in humidistat. By default, interlocking operation
(external equipment) is NOT enabled.
Interlocking operation is possible by connecting the remote controller to the humidier main unit’s L1
and L2 terminals. Refer to the installation manual for wiring details.
To enable interlocking operation:
1. Toggle the external equipment contact to OFF.
2. Turn o󰀨 the humidier and ensure the power indicator lights are o󰀨.
3. Press and hold the side button on the remote controller for 3 seconds. The power light will illuminate
green.
4. Press the STOP button on the remote controller. This will turn dryer mode indicator light ON or OFF.
• Turn ON the drying mode indicator light to enable interlocking operation with external equipment.
• Turn OFF the drying mode indicator light to disable interlocking operation with external equipment.
5. Press the side button 2 times to save the setting. The high indicator light will illuminate orange for 3
seconds. When the remote controller powers o󰀨, the process is complete.
Note:
Interlock operation, under normal circumstances, will allow you to operate the humidier with external
equipment with commands issued via external control signal input.
When the external equipment is OFF, the unit operation with the remote controller and the external
control signal input are invalidated. In such circumstances, the power and humidier lights on the remote
controller will blink for 3 seconds upon pressing the power button.
5.6.3 EnablingExternalSignalOutputs(DIPSwitchSettings)
External operation signals come from terminals 1 and 2 of the main unit. For a remote controller, this
means the power LED, and the humid. LED (if this setting is enabled).
This setting will allow you to output the operation signal to the humid. LED on the remote controller when
the unit is humidifying (humidier is ON and the humistat is also ON). This setting is useful for status
monitoring to check whether humidication is actually active, as opposed to simply being powered on.
Under default settings, only the operation signal is output (power LED) when the humidier is operating
and humidifying (i.e. the humid. light remains o󰀨). The default setting is useful for remote monitoring, to
prevent accidental forgetting of pin toggling.
To enable this setting, you must change the DIP switch settings on the main humidier’s control unit.
Remove power to the unit before making the change. Failure to do so will prevent the unit from saving
your changes.
Refer to the table below to see the DIP switch setting.

Remote starting and stopping via external control signal input (external command control) is possible.
However, even with this type of operation, remote controller installation is still required.
When using both a remote controller and external control signal inputs to start and stop the humidier,
the system utilizes second-Input priority. External control signal input types include steady-state input
and instantaneous input, with steady-state input signals used as default.
To enable external control signal input (remote starting and stopping):
1. Remove power to the humidier. Failure to do so may prevent changes from saving.
2. Connect control wires from the external controller to terminals 4, 5, and 6 on the main humidier
terminal block.
3. Set DIP switch 3 pin 1 ON or OFF for your conguration.

when operating and an OFF signal when stopping.
Pressing the remote controller’s power button when the
humidier operation is stopped will start operation, and
pressing it when the humidier is already operating will stop
operation.
Due to the use of second-input priority, contact must be
switched from ON to OFF in order to enable forced oper-
ation stoppage via ext. control signal input. Similarly, the
contact must be switched form OFF to ON in order to enable
forced operation start.

5.7 ConguringtheRemoteController
5.7.1 Address Setting
Address setting is required when connecting the humidier main unit(s) and remote controller.
The remote controller’s automatic address setting function detects the number of connected humidier units
(to the remote controller) and completes initial settings. The remote controller has been pre-congured
with address settings for a single humidier.
To perform address setting:
1. Supply power to all humidier units. All lights on the remote controller will blink for ~5 seconds. After
5 seconds, the lights will shut o󰀨 EXCEPT the alarm light. The alarm light will remain on.
2. On the remote controller, press the and hold the FAN button and the STOP button for at least 3
seconds. Address setting will begin. This process may take up to 2-3 minutes.
During address setting:
• The high fan and low fan light will blink at 2 Hz (2 times per second) for one minute. After one
minute, the lights will turn o󰀨.
• The humidication light will blink at half-second intervals for a total equal to the number of units
connected (ex. Unit will blink 3 times if there are 2 units connected to the main humidier - 3 units
total). This process repeats three times. After completion, the humidication light will turn o󰀨.
After address setting, all lights will turn o󰀨, including the alarm light.
3. Press the power button to turn on the humidier(s). The power and humidication light will turn on,
and the fans in the humidier will activate (after a 10 minute delay). The default setpoint is 40% RH.
After address setting, you may check the number of units connected to a single remote controller.
This will allow you to determine if there is a disconnected humidier.
5.7.2 AlarmSettings(formultipleunits)
When using a single remote controller to control multiple humidier units, alarm signals will be output
individually from each humidier unit via terminals 1 and 3.
Alarm signals are output when a unit’s safety protection function activates. Refer to chapter 7.2 on page 29
for more details about troubleshooting alarms.
Refer to the installation manual for details on installing external alarm outputs.
5.7.3 Selecting a Humidistat to Use
By default, humidity level detection is carried out by the humidistat built into the remote controller. Settings
must be changed to enable humidity level detection using an unsupplied humidistat.
To enable/disable an external humidistat:
1. Ensure that all lights on the controller are o󰀨.
2. Press and hold the side button on the remote controller for 3 seconds. The power light illuminates
green.
3. Press the fan button to toggle between the high and low fan light.
• The low fan light will enable an external humidistat.
• If the low fan light is o󰀨, the humidistat in the remote controller will be used.
4. Save the setting by pressing the side button 2 times. The high fan light will illuminate orange for 3
seconds. The remote controller powers o󰀨 once this process is completed.

5.7.4 Changing the Humidity Setpoint with the Remote Controller
The set humidity level can be adjusted in 5% increments between 35% and 70% RH.
The default setting is 40% RH. To check the current setpoint, refer to section 5.8 on page 18.
To change the humidity setpoint:
1. Turn o󰀨 the humidier and ensure that the power light is o󰀨 on the remote controller.
2. Press and hold the side button on the remote controller for 3 seconds. The power light will illuminate
green.
3. Press the side button 1 time. The power light turns o󰀨. The humidication light will illuminate green.
4. Press the FAN, STOP, or FIND button on the remote controller to toggle the lights on the remote
controller. The humidity setpoint corresponds to the light combinations in Table 6 on page 18.
5. Once the humidity level is set, save the setting by pressing the side button 1 time. The high fan light
will illuminate orange. The remote controller powers o󰀨 when the process completes.
