Time Providers
The clocks can use either a battery backed RTC module or a WiFi module. If you install both, the RTC will be
used only when the WiFi unit is not available!
Real Time Clock
By default, the clock comes with a Real Time Clock (RTC) module which provides a battery backed time
source that remembers the time even when the clock is not powered up.
WiFi Time Providers
More up to date is a WiFi real time provider, which logs into your home WiFi network and periodically
retrieves the time from Internet time sources. These are accurate to 1 second, and auto adjust for Daylight
Savings Time. You configure once, and then the module remembers the configuration forever.
Additionally, the WiFi time module gives you a easy to configure interface, which you can use to set up the
clock using a tablet, phone or computer.
Overview
Normally the clock is in “Time Display Mode”, which will show the time. If you press the button for differing
lengths, different things will happen.
“Short Press”
(less than 1 second): A temporary display will be shown for 5 seconds. This is useful if you
want to know the date, for example. The options here are given in the section “Temporary Display Mode”
“Medium Press”
(more than 1 second): The clock will go into “Setting Mode” to allow you to change
settings. If you have the WiFi module, you can change settings using a browser.
“Long Press”
(more than 8 seconds): The clock will go into “Tube healing mode”.
Read the section on
“Tube healing Mode” before using this mode.
This mode can damage your tubes if you don’t use it
correctly!
