7. Troubleshooting
The product is consisted of a total of three LEDs
representing the three main boards present
within the product. The Home Transmitter board
(contained within the EN Module), the Spa Trans-
mitter board (contained within the CO Module) and
the Water Monitoring board (contained within the
CO module) The CO and EN module communicate
together via an RF link while the Water monitoring
board communicates directly to the CO transmitter
board since they are both contained within the CO
module. The Home Transmitter is responsible for
the Ethernet communications, the Spa Transmitter
is responsible for the spa communications and
the Water Monitoring board is responsible for
acquisition of water sampling.
Home Transmitter (EN Module) LED status
This module’s LED can show various status
conditions, as indicated below.
Rapidly flashing YELLOW color:
The Home Transmitter is in pairing mode when this
color is shown (the pairing switch was pressed). Until
a pairing successfully completes, the application
cannot connect to the spa. To complete the pairing,
you must turn off the spa (using its breaker), wait a
few seconds and then flip back the breaker to on.
The pairing will then occur within a few seconds.
If not, then the Spa Transmitter is either incorrectly
connected, out of range, or defective.
If the in.touch 3 modules were previously paired
and the pairing switch is accidently pressed, simply
unplug the Home Transmitter USB power cord and
re-plug it (thereby resetting the Home Transmit-
ter). The modules should then normally reconnect
together.
Once out of pairing mode, the Home Transmitter
will display another color.
For each of the following colors, the information
applies whether the LED is blinking or not. If the
LED is blinking, please also refer to the Blinking LED
section below.
RED color:
The Home Transmitter is not detecting a router.
Until this is resolved, the application cannot connect
to the spa.
Make sure the router is powered and working
correctly (i.e. test it using another computer or
device connected to the same LAN port you intend
to use). Make sure the Ethernet cable is correctly
connected at each end (LAN port on router end,
and the Home Transmitter.) If the problem still
occurs, try connecting with another cable.
If a computer (or other device) works fine on
the LAN port, and the cable is fine, then the home
transmitter is likely defective.
GREEN color:
The Home Transmitter is connected to a router (an
IP address was assigned), but the in.touch 3 server
is not reachable.
This is very likely a router configuration issue, so
refer to your router’s User Manual. It may be due to
Port 10022 being closed. Normally, this port is open
by default in commercial routers, but different
routers may have different behaviors.
If Port 10022 is confirmed as open, then some other
internal configuration is preventing the router from
accessing Internet. The server may also simply be
temporarily “offline” for servicing/maintenance,
so try again later. The problem can also be due
to the Internet connection (WAN), a router
misconfiguration, or your Internet Service Provider
(ISP) has issues with its network connection.
BLUE color:
This is the normal state of the Home Transmitter
LED. It has a full Internet connection, with access
to the in.touch 3 server. If your device and appli-
cation have access to the Internet (either via Wi-Fi
or cellular data such as 3G, 4G, or LTE), then you’re
good to go!
Spa Transmitter (CO Module) LED status
This module’s LED can show various status
conditions, as shown below.
Rapidly flashing YELLOW color:
The Spa Transmitter is in pairing mode when
this color is shown. This normally briefly occurs
automatically during power-up of the spa (i.e. right
after the breaker is flipped on). This could also
occur if the Spa Transmitter was never paired
(which is very unlikely, as they are shipped paired
from factory). Refer to the pairing section below
if your unit has not been paired, so you may
complete the process.
