7-day Solar Programmable Wall Switch
The TI072 programmable wall switch has been designed to control lights and motors:
nCut power at the circuit breaker to avoid electric shock.
oRemove the existing switch. (For a 3-way installation, identify and label the wire that is connected to
the “common” screw.)
pInstall the new switch.
qApply power at the circuit breaker.
SINGLE-SWITCH INSTALLATION
EXISTING 3-WAY INSTALLATION
Connect the LOAD wire on the TI072 to the “common” wire, which you identified when removing the old
switch. Connect the NEUTRAL wire to the neutral (white) wires. Connect the LINE and 3 WAY wires to the
two remaining wires. At the other 3-way switch, connect the jumper wire between the “common” screw and
the screw where the LINE wire of the TI072 is connected.
NEW 3-WAY INSTALLATION
The TI072 will turn the lights on at sunset and turn them off at 11:00 pm by default. If these settings are
appropriate for you, you only need to set the time and date (see shaded zone in the menu flowchart sheet).
If the switch’s sunset time does not correspond to the actual sunset time, see sections 5.3.3 and 5.3.4.
5.1 Mode Menu
You can use the Mode menu to select one of the three modes of operation (see sections 5.1.1 to 5.1.3).
5.1.1 Manual Mode
In Manual mode, the TI072 operates like a regular switch. To turn the lights on or off, briefly
press the main button. The icon appears when the switch is in Manual mode.
5.1.2 Automatic Mode
In Automatic mode, the TI072 turns the lights on or off according to the set programs (see
Section 5.4). The icon as well as the current program number are displayed.
5.1.3 Random Mode
In Random mode, the TI072 has no specific times to turn the lights on or off. This mode is
designed to give the impression the house is occupied during your absence. It is similar to the
Automatic mode except there is no fixed program. The programs are automatically set to
different times by the TI072 every day. The icon appears when the switch is in Random mode.
The first “On” program occurs at sunset. Each “On” program lasts between 1 hour and 1
hour and 30 minutes; each “Off” program lasts between 15 and 30 minutes. The last “Off”
program occurs between 10:30 pm and midnight.
5.1.4 Temporary Override
When the TI072 is in Automatic or Random mode, you can press the main button at any time to override the
default state for the current program. The light will turn off if they are on and vice versa. The icon (On or Off)
of the new state flashes to indicate that the state is temporary. The new state is maintained until you press
the main button again or till the next “On” or “Off” program.
5.2 Time Menu
The time display flashes on the screen when the time has not yet been set or after a 4-hour power outage.
Use the Time menu to select the time format (12-hour or 24-hour) and to set the clock and date.
NOTE: The date is used to determine the sunset and sunrise times.
