e7w Smart Wall Plate (SWP) related issues
The e7w display shows SWP and you can’t use the e7w
If is permanently displayed and you cant use the e7w , the e7w has never made a connection with its
“Smart Wall Plate” (SWP) since batteries were installed into the e7w.
The e7w SWP is physically mounted to the wall or electrical box and the e7w thermostat body snaps onto the
SWP and is secured with 2 screws.
Spring loaded pins on the e7w make contact with a memory chip on the SWP that stores the e7w’s Room ID,
PAN ID and RF Channel after it has been entered during e7w installation. With this information stored in the
SWP, you should be able to attach a new replacement e7w to the SWP and the Room ID, PAN ID and RF
Channel stored in the SWP will be loaded into the new e7w and stored without having to enter Service
Parameter mode on the e7w to enter the values.
Important: ONLY the e7w’s Room ID, PAN ID and RF Channel get stored into the connected SWP. HVAC
control settings and other configurations of the HVAC controller partner of the e7w (ie X47) DO NOT get
copied to the e7w SWP. If you need to replace the HVAC controller partner, you should refer to applicable
installation/commissioning documentation for the HVAC controller.

If the e7w is constantly displaying SWP after attaching it to the SWP, perform the following troubleshooting
steps:
1. Un-screw the 2 captive screws at the bottom of the e7w that attach the e7w to the SWP and re-fit the
e7w to the SWP.
2. Make sure 2 tabs at the top of the e7w are fully inserted into the 2 slots at the top of the SWP, then
rotate the bottom of the e7w and push onto the SWP so the 2 tabs at the bottom of the SWP snap into
the slots at the bottom of the e7w.
3. Screw in the 2 captive screws to permanently mount the e7w.
4. Wait 10 seconds and see if the SWP indication clears and is replaced by a different indication.
➢If SWP cleared and a temperature value appears, the e7w read the stored Room ID, PAN ID and RF
Channel stored in the SWP and began operation. Raise and lower the displayed target temperature
and verify the rooms HVAC unit responds as expected.
➢If SWP cleared but 2 horizontal dashes appear , press the F/C button:
•If the 2 dashes clear, followed by all of the display icons appearing briefly , followed by a
temperature value , the e7w read the stored Room ID, PAN ID and RF Channel from the SWP and
began operation. Raise and lower the displayed target temperature and verify the rooms HVAC
unit responds as expected.
•If Parameter , rid and 2 horizontal dashes appear , the e7w is either a brand new and has never
been initialized with its Room ID , PAN ID and RF Channel , or the e7w was factory reset and has
never been initialized with its Room ID , PAN ID and RF Channel.
You must complete the initialization process. Refer to Appendix 1 of this document
5. If SWP continues to be displayed, repeat steps 1-4 again.
If SWP still continues to be displayed on the e7w after repeating steps 1-4, there is an issue with the SWP
or the e7w. The e7w is not able to establish communication with the SWP EEPROM chip. Remove the
e7w from the SWP and look at the SWP EEPROM board and the spring loaded pins on the e7w. Refer to
Figure 1 on the previous page that shows the EEPROM board and e7w pins.
Is the EEPROM memory board on the SWP missing , or the screw that attaches the EEPROM memory
board missing? Do the SWP pins on the e7w look damaged?

If any of the above are true and you want the SWP feature to work, you need to replace the SWP, the
e7w or both.
If you need to use the e7w immediately , or there is a guest in the room and the installed e7w needs
to work, manually force the e7w out of SWP missing mode by pressing and holding the F/C button for 5
seconds. The following should occur after pressing and holding the F/C button for 5 seconds:
➢If the e7w has previously been initialized, it will begin normal operation and you should see a
temperature displayed on the e7w. But, if the e7w subsequently has its batteries removed and
replaced, due to the issue connecting to the SWP, on startup it will again enter SWP mode and
display SWP.
➢If Parameter , rid and 2 horizontal dashes appear , the e7w is either a brand new and has never
been initialized with its Room ID , PAN ID and RF Channel , or the e7w was factory reset and has
never been initialized with its Room ID , PAN ID and RF Channel.
You will need to enter the Room ID , PAN ID and RF Channel as described in Appendix 1. But, if
the e7w subsequently has its batteries removed and replaced, due to the issue connecting to
the SWP, on startup it will again enter SWP mode and display SWP.
The e7w in a guestroom failed , you have no replacement or spare e7w’s , and you want to replace
it with an e7w from a different room until you can obtain a new e7w.
When the e7w that you are replacing was initially installed and the Room ID, PAN ID and RF Channel were
entered , this was stored in the SWP (Smart Wall Plate) attached to the e7w.
To install the e7w obtained from a different room onto the SWP:
1. Remove the failed e7w from the SWP.
2. If batteries are still installed in the replacement e7w obtained from a different room , you MUST
remove at least one AA battery to power down the e7w. Then, re-insert the any removed AA
batteries to power up the e7w.
The e7w should display SWP ( )
3. Attach the replacement e7w to the SWP in the room where the e7w failed . The instant you attach
the replacement e7w , it should read in the stored Room ID, PAN ID and RF Channel from the SWP ,
store it and begin normal operation.
4. If SWP cleared from the display and a temperature value appears, the e7w read the existing Room
ID, PAN ID and RF Channel stored in the SWP and began operation. Raise and lower the displayed
target temperature and verify the rooms HVAC unit responds as expected.
If after connecting the replacement e7w to the SWP , “SWP” appears and remains on the e7w display, the e7w
is not connecting to the SWP. Go to the “The e7w display shows SWP and you can’t use the e7w” section
on page 3 and follow the steps.

The e7w in a guestroom failed and you want to replace it with a new out of the box e7w
1. Remove the failed e7w from the existing SWP (Smart Wall Plate) attached to the wall or electrical box .
2. Remove the new e7w from the box. You should not need the new SWP provided in the box.
3. Insert the provided AA batteries into the new e7w. It should power up and display SWP ( )
4. Attach the new e7w to the existing, installed SWP.
5. The e7w should briefly display all characters on the LCD display, then display a temperature value.
This indicates it connected to the SWP and read in the stored Room ID, PAN ID and RF Channel.
If desired, you could enter service parameter mode on the e7w and verify the Room ID, PAN ID and RF
Channel values are correct. Refer to Appendix 2.
If SWP cleared from the display after attaching to the SWP , but 2 horizontal dashes appear instead
of a temperature value, press the F/C button and see if the temperature value then appears.
If so, go to step 6.
If the 2 horizontal dashes cleared but were replaced by “Paramater” “rId” and 2 dashes, the e7w
failed to read in the stored Room ID, PAN ID and RF Channel from the SWP and is expecting you to
enter the required Room ID, PAN ID and RF Channel.
The SWP was never actually initialized with a Room ID, PAN ID and RF Channel , and you must now
enter those values. Refer to Appendix 1: Setting the Room ID, PAN ID and RF Channel into the e7w
during Initialization. Then , return here and do Step 6.
6. Raise and lower temperature on the new e7w and verify it is controlling the room HVAC unit.

Rebooting the e7w back to Factory Default settings
It is possible to reboot the e7w back to its default Factory settings. Rebooting the e7w does the following:
➢Defaults its Room ID to 65535
➢Defaults its PAN ID to 0
➢Defaults its RF channel to 26
➢If connected to a SWP (Smart Wall Plate), erases any stored Room ID, PANID or RF Channel in the SWP
Cases where you would Factory Boot the e7w are:
➢You are not sure what the current settings are in the e7w and you want to default it back to known
factory settings
➢You have connected the e7w to what you think is a configured SWP, but the e7w Room ID, PAN ID and
RF Channel are not being set to the correct values that should be stored in the SWP.
➢The e7w is not functioning correctly, and it is possible that a factory boot will recover the e7w.
To Factory Boot the e7w :
1. Make sure the e7w is connected to its SWP
2. Enter Service Parameter mode on the e7
3. Press the Up or Down arrow buttons to go to the rSt (Reset) parameter
4. Press the MODE button to display the value.
5. Change the value to 255 using the Up or Down arrow buttons.
6. Press the FAN button to initiate the Factory Reboot.
7. The display will go blank, followed by “4” being displayed, followed by all LCD characters being
displayed, then finally 2 horizontal dashes. Upon pressing any button, “Parameter”, “rid” and 2 dashes
will appear, indicating the Factory Boot is completed and the e7w requires initialization where you
must enter the required Room ID, PAN ID and RF Channel.

e7w display related issues
e7w display just shows a single temperature value with no Fan Speed or A/C Mode
Possible Reason:
The e7w has entered into “dormant” mode to conserve battery power. This is a normal operation of the e7w.
The e7w will automatically enter dormant mode after 4 seconds with no button presses or user interaction and
displays the guest selected target temperature.
The instant you press a button on the e7w , it will return to displaying A/C Mode, Fan Speed.
The e7w displays 2 dashes ( - - ) and when you try to use the e7w there is only rid , PAn and rF
options available
Possible Reason:
The e7w is brand new, fresh out of the box and has not been initialized yet , or it has been rebooted back to
factory settings and requires initialization. Refer to Appendix 1: Setting the Room ID, PAN ID and RF Channel
into the e7w during Initialization
e7w display is blank
Possible Reasons:
➢The 4 AA batteries are fully discharged and need replaced
➢One of more of the AA batteries is not fully seated and making sufficient contact with the battery
terminal
➢The e7w has been damaged or is defective

e7w Battery related Issues
A Battery symbol has appeared in the lower right corner of the e7w display in one or more rooms
The e7w displays the battery symbol when it has detected the voltage of the installed 4 AA batteries has
dropped below 4 VDC. Replace the batteries in the e7w with 4 new alkaline AA batteries. The low battery
alarm should clear within 1-2 minutes after replacing the batteries.
The actual battery voltage can be read from the e7w by entering Service Parameter mode and going to the
bAu parameter and viewing the displayed value. Refer to Appendix 6 of this document for details.
The value is 0 to 6 VDC scaled between 0 and 255. Take the displayed value, divide by 255 and multiply by 6
to get the voltage. A displayed value of 255 indicates 6VDC. A displayed value if 170 indicates 4 VDC
Note: Future versions of the e7w will display its battery voltage in a more user friendly fashion.
In addition to the Low Battery symbol appearing on the e7w display, if the hotel has an Inncom network
installed with an Inncom Server running INNControl 3 or INNControl 5, the room should appear in any
generated Low Battery reports and a “Device with Low Battery” indication should appear for the room in
IC3/IC5.

The Low Battery symbol has appeared in the lower right corner of the e7w display in a room, but
no “Device with Low Battery” indication has appeared for the room in IC3/IC5 Room View or no
Low Battery alarm occurred in IC3 or IC5 .
Possible Reasons:
➢The room the e7w is installed in is not correctly setup to communicate with the Inncom server. There
must be a device in the room configured as the room gateway that is communicating through an Edge
Router or B576 Floor Bridge to the Inncom server. The e7w must be set to the same Room ID, PAN ID
and RF Channel as that room gateway. Verify the Room ID, PAN ID and RF Channel set into the e7w
are correct for the particular room and perform a WAN test (see Appendix 7) from the e7w service
parameter mode to verify the Room Gateway for the room is online with the server. Verify you can
Ping the room gateway device address using the e7w Pn6 (Ping) parameter (see Appendix 8).
➢It can take time before the low battery condition of the e7w gets reported to the server.
The e7w only reports its battery state after the e7w connects to its Smart Wall Plate following battery
insertion and every 18 hours. It sends a “Device Information” message that includes its battery state
that is routed through the Room Gateway to the Inncom server. This message reports the e7w
battery status as normal (> 4VDC) or low (< 4VDC).
Therefore , if the voltage of the 4 AA batteries drop below 4VDC during normal operation, the next
every 18 hour Device Information message sent by the e7w will report a low battery condition, and
the Low Battery indication for the room in IC3 /IC5 will be set and a low battery alarm will occur.
I replaced the batteries in the e7w, but there is still a low battery indication for the room in IC3/IC5
Possible Reason:
➢The e7w was not correctly connected back to the SWP (Smart Wall Plate) after replacing the batteries.
Verify the e7w is fully connected to its SWP. The e7w would be displaying “SWP” if it was not fully
connected to the SWP.
1. Un-screw the 2 captive screws at the bottom of the e7w that attach the e7w to the SWP and re-fit
the e7w to the SWP.
2. Make sure 2 tabs at the top of the e7w are fully inserted into the 2 slots at the top of the SWP, then
rotate the bottom of the e7w and push onto the SWP so the 2 tabs at the bottom of the SWP snap
into the slots at the bottom of the e7w.
3. Screw in the 2 captive screws to permanently mount the e7w.
4. Wait 10 seconds and see if the SWP indication clears and is replaced by a temperature value. This
indicates the e7w connected to the SWP. The low battery indication should clear for the room in
IC3/IC5 within 1-2 minutes.
If the low battery indication in IC3/IC5 does not clear, it is possible the message sent from the e7w
to the server reporting its battery state after inserting the new batteries and connecting the e7w
to the SWP did not reach the Inncom server. It is only one sent one time after connecting the e7w
to the SWP following battery replacement, and then is sent every 18 hours.
