Cypress Wireless Communications

• Uses Cypress Semiconductor wireless
technology – first deployed over six years
ago, with over 25 million nodes in use today.

• Hybrid mesh networking that is fast, easy to
use, highly reliable and self-healing

• Allocate (1) Repeater for up to every (15)
WPTs

• Up to 225 WPTs with 14 Repeaters and 1
Hub are supported per GBC.

• (14 Repeaters + 1 Hub) X 15 WPTs =
225 Total WPTs

• The WPT network allows a total of (6) data
hops back to the Hub

• Think of a data hop as a repeater. If 3
repeaters are required for a WPT then
you have 3 hops.

2.4 GHz DSSS radios, +20dBm (100mW) peak output

NOTE: Do not use where cell phones or

WiFi are prohibited (i.e. hospital
operating rooms), or in environments
requiring temperature validation.

Cypress Confidential

Network Formation / Reformation

• The WPT network automatically form once the components are powered.
The components should be powered up as follows:

- Hub / server

- Repeaters

- WPTs

• As they are powered, Hub, Repeaters, and WPTs begin communicating
with each other and determining best communication routes.

• Network formation only takes a few seconds in most cases, but it can take
a few minutes for all devices to be “negotiated” into the network.

- For example, if a Repeater drops off the network it can take some time for the
network to “re-negotiate” a new path (self healing).

• Remember, WPTs only associate themselves with one device (directly
with the Hub, or with a Repeater)

Remember

• The WPT thermostats are zone control only

• The thermostat controls the terminal unit in the same exact way as the old Johnson or Honeywell
pneumatic thermostat.

• For terminal units having both heating and cooling controls (i.e fan coil unit, VAV w/ reheat),
consider using the WPT deadband thermostat.

• The WPT thermostat has an standard pneumatic thermostat built inside. Like any pneumatic
thermostat, this is a proportional control device only. The WPT does not have integral reset (PI
control) parameters.

14

Cypress Confidential

Thermostat Identification

Use the following guidelines for proper selection of the WPT model

1) Is the Thermostat to be retrofitted a Wall/Room Thermostat?

- Note: WPT does not replace the Remote Bulb thermostats

2) Is it a one-pipe (low air capacity) or two-pipe (high air capacity) thermostat?

3) Is the control action direct or reverse acting?

- Verify existing thermostat operation by adjusting the setpoint dial and noting the operation. This is
particularly important if there is no model number readily available on the thermostat.

- Direct acting: An increase in temperature above setpoint results in an increase in the branch line air
pressure.

Example:

Room temperature 72.0
Setting the setpoint to 55.0 (branch pressure increases)
Setting the setpoint to 85.0 (branch pressure decreases) Normally open heating valve

- Reverse acting: An increase in temperature above setpoint results in a decrease in the branch line air
pressure.

Example:

Room temperature 72.0
Setting the setpoint to 55.0 (branch pressure decreases)
Setting the setpoint to 85.0 (branch pressure increases) Normally closed heating valve

WPT Wireless Network Planning Overview

• Wireless network planning involves
selecting good locations for the
Repeaters and Hub

• Depending on the building, the
wireless range
and the number of Repeaters required
may differ

• More than one Green Box
may be used at larger sites. Each
Hub and its associated Repeaters
are considered a separate network.

Wireless Performance in Buildings

• Cypress wireless has been installed in many different types of sites
– low-rise office buildings
– high-rise commercial buildings
– industrial plants

• Typical wireless ranges for a single “hop” are:

• Repeaters allow for multiple “hops” which extend the communications range

of the system

Line of Sight

300 ft open halls
150 ft in open office floor
100 ft in corridors

Drywall / Paneling 100 ft, through five walls

Brick Walls 60 ft, through three walls

Ceilings 25 ft, through single ceiling

20

Cypress Confidential

Factors Reducing Wireless Range

• Wireless range is affected when metal obstacles are in the
line of transmission.

• A solid sheet of metal and some rebar reinforced concrete
present the greatest obstacles.

• Try to note the following objects and avoid them in the line of
transmission:

- Hollow lightweight walls filled with insulating metal foil

- Office equipment and furniture such as book shelves, file cabinets,
metal partitions, computer racks

- Metal reinforced concrete walls, pillars and columns

- Glass walls with metal coating

- Plumbing and electrical risers

- Elevator shafts and stairwells

- Mechanical and electrical equipment rooms

The bigger the metal obstacles in the transmission path, the shorter the wireless range.

21

Cypress Confidential

• Wireless Range Test Kit (RKIT)

- Tool for determining received signal strength indication (RSSI) between points

- Enhanced RKIT; Instructions printed on the RKIT devices; continuous updates
for 30 seconds

- RSSI levels (1-5)

• 3 - 5 (Acceptable quality)

• 1 - 2 (Poor quality, unacceptable)

• “--“ indicates no wireless coverage

- Avoid holding the RKIT near the antenna

• Influence from the body could adversely affect the radio range

• Antenna radiation patterns

Best practices

• When you have locations with multiple GBC make sure you use different

Network ID numbers on each GBC.

- Even buildings within 1000ft may receive crosstalk

• Many times the core will be cool only and perimeter will have cooling with

reheat requiring different thermostat types. Both should be checked.

• If a section of a building has been remodeled check thermostats to verify

type (direct acting or reverse acting).

• Locating the GBC in the center of the building close to power and a LAN.

ID assignments

• WPT

- Useful to number per floor or area (1xxx = 1stfloor, 2xxx = 2ndfloor…)

- If possible, number in a clock-wise manner through the floor or some other
logical pattern to help with maintenance

• RWAL

- Left most digit doesn’t matter, but right most digit should be numbered with
the lower number closest to the Hub

• Repeaters with an ID ending with 1 will be discovered first

• Do not repeat the right most digit in a repeater ID number for a given network

36

Cypress Confidential

Troubleshooting Tips

Make sure there is no other Receiver with
the same RKIT ID in operation nearby.

Another Receiver with the
same RKIT ID is in
operation nearby.

Transmitter shows a valid RSSI
reading even though the Receiver
is turned off.

Make sure there is no other Transmitter
with the same RKIT ID in operation nearby.

Another Transmitter with
the same RKIT ID is in
operation nearby.

Receiver is flashing its override
indicator even though the
Transmitter is turned off.

Make sure the RKIT ID on both devices are
the same

RKIT ID mismatch.

Both Receiver and Transmitter are
in range, but they have no
communication after range test is
started, i.e. Transmitter always
displays “--“ and Receiver is not
flashing its override indicator.

Check the batteries.

No batteries inserted,
batteries inserted
incorrectly, or batteries
are low

Either Receiver or Transmitter
does not display battery icon after
pressing any buttons.

Installing the WPT – Step 1

Remove the existing thermostat and wall plate

(Figure shows 2-pipe thermostat. Procedure is the same for a 1-pipe thermostat.)

1. Remove the old thermostat cover (typically requires 0.050” or 1/16” Allen driver)

2. Remove old thermostat from wall base plate.

3. Unscrew wall mounting plate from wall.

4. Remove tubing from old thermostat bracket and HOLD ON TO THE TUBING. If it is tight it
will pop back into the wall and you will need to retrieve it.

5. HOLD ON TO THE TUBING and cut off tubing 1/2” back from the old thermostat bracket.
We want fresh tubing ends to fit onto the WPT tubing port.

6. If tubing is short you will need to extend the length by adding a coupler and a short 4 to 6
inch length of tubing. Don’t forget the internal spring in the tubing, this keeps the tubing
from kinking and closing the main air flow off to the thermostat.

7. HOLD ON TO THE TUBING. Now you are ready to install the WPT wall Bracket

75

Cypress Confidential

Installing the WPT – Step 2

Mount universal adapter plate, connect pneumatic lines to

WPT, mount WPT to wall, and install WPT cover plate

(Figure shows 2-pipe thermostat. Procedure is the same for a 1-pipe thermostat.)

1. HOLD ON TO THE TUBING Slide the tubing through the center of the large hole in wall mounting bracket. It is
important that the tubing has room to slide back into wall cleanly so it does not get pinched off as you mount
the WPT to the wall bracket.

2. HOLD ON TO THE TUBING and attach the mounting bracket to wall using existing anchors (if possible).

3. HOLD ON TO THE TUBING and place the tube with air blowing, on to the larger of the 2 fittings on to the back
of the WPT (the port on the left for a 2 pipe WPT). This is the main air inlet (supply line).

4. Place the 2nd tube onto the branch port (which should be blowing air) on the back of the WPT thermostat
(the port on the right).

5. DOUBLE CHECK THAT BOTH TUBES ARE PRESSED ALL THE WAY ON AND BOTTOMED OUT ON THE FITTING.

6. Slide the tubing back through the plate and into the wall.

7. Check to make sure the tubing slides into the wall smoothly and does not get kinked.

8. The WPT slides over the wall bracket at the top and catches allowing the WPT to hang and set into place and
secured with the 2 captured screws at the bottom. Do not over tighten the screws, just snug to tighten.

Verify HVAC operation using the WPT (DA)

1. Adjust WPT setpoint to 55 degree and wait and watch.

2. Check Branch pressure

• A direct acting thermostat will be in cooling mode and will build branch pressure (verify
pressure is at 15 lbs or higher)

• A/C actuator will start to open fully (at around 13 lbs)

• You should see the supply air temp drop to 65 degree or lower (check with an IR
temperature gun)

3. Adjust WPT setpoint to 85 degree and wait and watch.

4. Check Branch pressure

• A direct acting thermostat will be in heating mode and branch pressure will drop to 0
lbs.

• At around 5 lbs the heating valve should open and air temp should warm up.

• At 0 lbs the valve is open full and the supply air temp should warm to 90 degree or
higher (check with an IR temperature gun)

If branch pressure will not build on the WPT

• Loosen and lift WPT off wall bracket, as you pull away from wall look behind WPT
to check for kinked main air line.

• Remove branch line and place your finger over the port and repeat # 2 above.

• If pressure will build with your finger over the port, then there is a possible branch line
leak.

• If there is no pressure, then replace the WPT and return the unit

Calibrating the WPT – Step 1

1. Remove the front cover of the WPT and make sure that the WPT is
acclimated to the ambient temperature.

2. Turn on the air compressor

Notes

1. Acclimating the thermostat can take 30 minutes or more after attachment to the wall. The bimetallic strip is
very sensitive to body heat. Keep hands and breathe away from WPT to minimize calibration error.

2. The black throttling range adjuster has been factory set to the location marked on the lever. The factory
setting provides a Throttling Range (TR) of 4°F. This TR adjuster MUST NOT BE MOVED in order to ensure
proper operation and accuracy of the WPT. The throttling range is the amount of temperature change
required for the WPT to produce a full output change.

3. Single pipe WPT might take a longer time to respond during calibration. Please allow sufficient time to
calibrate the WPT accurately.
