Bulletin TE-490W-QS
Series 490W Hydronic Differential Pressure Manometer is the most accurate
and easy to operate manometer on the market. By using wireless transducers and
a versatile handheld, a single operator can monitor and balance a hydronic system
in less time than traditional hydronic balancers. The Series 490W utilizes mobile
technology to communicate via a Bluetooth connection with the transducers to
monitor differential pressure and ow on up to three different valves. Being wireless
means there are no hoses to carry, snag on equipment or needing to be drained. The
490W includes Dwyer’s Hydronic Application Software that contains valve charts for
numerous manufacturers, which converts differential pressure to ow directly on the
screen.

OPERATION
Powering On/Off
To turn on the handheld, press and hold the power button. Wait approximately 15
seconds for it to fully power on. Swipe to unlock the unit.
To turn off the unit, either press and hold the power/sleep button and press Power Off
when prompted on the LCD or press the reset button.
Handheld Battery
The universal handheld utilizes an internal rechargeable battery. The battery symbol in
the top right of the screen shows the status of the battery.
TRANSDUCER BATTERY INSTALLATION
The unit is shipped with a CR2050 lithium battery installed. To replace battery, unscrew
black top cap from transducer. Tilt transducer to remove old battery. Install new battery
and replace top cap.
Low Battery Indicator
A weak battery can cause improper operation or inaccurate measurements. The unit
is supplied with a battery that can last up to 2 years, depending on usage. When
transducers are sent in for annual recertication, the battery will be replaced.
Battery life depends on its capacity, operating temperature and
signal transmission interval. When battery replacement becomes
necessary, use only a CR2050 or CR2032 type such as a Sony CR2050W or
CR2032W.
NOTICE
When the 490W is received, the handheld test instrument will only
have a partial charge. Be sure to fully charge before using. When
the battery is low, the battery symbol will turn red. When this occurs, use the included
USB charging cable and charging power adapter to recharge the unit.
NOTICE
The handheld test instrument comes factory paired to the included
wireless pressure transducers.

Discovering the wireless pressure transducer
In the Sensor Discovery screen press the scan button to connect to transducers.
Note: In this screen, up to three sets of transducers may be paired simultaneously
to read differential pressure or up to six transducers may be may be paired to read
single pressure.
Be sure the selected transducers’ MAC addresses have the
same maximum pressure. Each transducer is marked with a red
(high) and blue (low) band to distinguish which transducer is high or low. Once the
transducers are paired by MAC Address, select the High Side box for the transducer
which has the red band. Its paired transducer will automatically be set to the low side.
After the high and low transducers are marked, press the Selected box to choose
pairs to use.
NOTICE
The transducers will automatically go into low power/sleep mode
to conserve battery energy. The transducers exit low power mode
upon receiving communications from the Hydronic Application

Reading Differential Pressure and Flow
Data can be collected in the Flow Reading screen after the transducers connection
status indicates CONNECTED. The application converts differential pressure to ow
directly on the screen.
FCC RF EXPOSURE INFORMATION AND STATEMENT
The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device
types: S09 (FCC ID: ZHN-W63) has also been tested against this SAR limit. The
highest SAR value reported under this standard during product certication for use at
the ear is 0.430 W/kg and when properly worn on the body is 0.772 W/kg. This device
was tested for typical body-worn operations with the back of the handset kept 1.5
cm from the body. To maintain compliance with FCC RF exposure requirements, use
accessories that maintain a 1.5 cm separation distance between the user’s body and
the back of the handset. The use of belt clips, holsters, and similar accessories should
not contain metallic components in its assembly. The use of accessories that do not
satisfy these requirements may not comply with FCC RF exposure requirements and
should be avoided.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and (2)
This device must accept any interface received, including interference that may cause
undesired operation.
Note: The manufacturer is not responsible for any radio or TV interference caused by
unauthorized modication to this equipment. Such modications could void the user’s
authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio
or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try and correct the interference by one of more of the
following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected
• Consult the dealer or an experienced radio/TV technician for help
MAINTENANCE/REPAIR
Upon nal installation of the Model 490W, no routine maintenance is required. The
Model 490W is not eld serviceable and should be returned if repair is needed. Field
repair should not be attempted and may void warranty.
WARRANTY/RETURN
Refer to “Terms and Conditions of Sale” in our catalog and on our website. Contact
customer service to receive a Return Goods Authorization Number before shipping the
product back for repair. Be sure to include a brief description of the problem plus any
additional application notes.
Do not dispose of as unsorted domestic or municipal waste. Consult
retailer or local authorities for recycling information.
ZEROING THE TRANSDUCERS
In order for the transducers to be zeroed, place them near the location of the process
connection. Note: Be sure to zero transducers outside the process connection without
any pressure applied.
In the Hydronic app, press the “Zero” button (Ø) to zero the pressure readings. The
zeroing process will began by displaying a dialog box “Zeroing Please Wait”. Once the
dialog box disappears, the transducers can be connected to the process connection
to read pressure.
