Honeywell INNCOM e7w Troubleshooting Manual page 4

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?
