24 VAC wiring and power specications
Follow all National and Local Building Codes when installing clocks.
All clocks should be connected to a single power source. If multiple power sources are needed to accommodate the
load of the clocks, all of the power sources should have the same rating and be installed on separate branch circuits.
Never install different size power sources on the same branch circuit.
• For installations where 24 VAC wiring exists: gauge/length of the wire and rating for the supply transformer should be
veried to ensure adequate current supply and voltage for all connected devices.
• For new installations: supply wire gauge should be determined to ensure an acceptable voltage drop based on
installed length from the supply transformer to the most distant clock to ensure minimum voltage (18 VAC) is
assured.
• Use two wire nuts, sized appropriately for the gauge of wire, to secure building supply wires to wires extending from
the clock power supply.

Set display settings
Levo Digital Clocks and Timers have a dip switch control panel that sets its display settings. To change the factory
default settings, from the back side of the clock remove the small rectangular access panel. Setting changes can be
made while the clock/timer is ON and changes will take effect within a few seconds.
NOTE
When power is rst applied to the clock/timer or the reset button is pushed, a decimal point will ash for
approximately three minutes while its receiver is turned on to search for a Transmitter signal. If the
clock does not receive valid time data from the Transmitter for 3 days, the red colon on the clock will
ash.
Set LED dimmer display
The LED display is set to 100% by factory default.
To dim the LED by 25%, set the OPTIONS, DIM switch 1 to the OFF position and DIM switch 2 to the ON position, as
illustrated below.
To dim the LED by 50%, set the OPTIONS, DIM switch 1 to the ON position and DIM switch 2 to the OFF position, as
illustrated below.
Page 11

To dim the LED by 75%, set the OPTIONS, DIM switch 1 to the ON position and DIM switch 2 to the ON position, as
illustrated below.
Set alternating time/date
To set the display of a to alternate between the current time and date, set the HR OFFSET- Time/Date switch (1) to the
ON position, as illustrated below.
Page 12

Set display to 24-hour time
To display 24-hour time, set the HR Offset - 12/24 HR switch (2) to the ON position, as illustrated below.
Set PM indicator
To enable the PM dot indicator, set the OPTIONS - PM DP switch (6) to the ON position, as illustrated below.
Set offset hours
The Clock/Timer displays the time received from the Transmitter. The hour offset is for application use when the clock/
timer is to display the time for another Time Zone.
By moving the appropriate “HR OFFSET” dip switch(s) and the direction (+/-) dip switch, any full-hour time can be
displayed. The “HR OFFSET” switch designates how many hours are offset from the current Transmitter Time Zone.
The clock reads the hour offset on start up, when the RESET button is pushed, and each time the clock receives data
from the Transmitter for the offset hours to go into effect.
Page 13

Set audible buzzer (timer models only)
The audible buzzer is only on the count-up and count-down timer function. To enable the buzzer feature, set the
OPTIONS - Buzzer switch (3) to the ON position, as illustrated below.
Set Programmable Timer mode (programmable timer only)
For Programmable Timer models, the timer schedule is congured in the Primex Event Scheduler Pro software to the
schedule ID controller 24. The schedule is downloaded from the Event Scheduler Pro to the system Transmitter,
allowing the Transmitter to broadcast the schedule.
To enable a programmable timer to receive the broadcast schedule from the Transmitter, set the PT/TC Switch (5) to
the ON position, as illustrated below.

Installation requirements
• Refer to the Important Safety Instructions before installing, operating or performing maintenance of clocks.
• Before installing, set the clock display settings [11].
• Clocks must be installed at a location within adequate transmission range of the Transmitter.
• Before installing, verify the Transmitter is operating properly and sending a signal with adequate building coverage.
Transmitter with Internal Antenna: transmits (broadcasts) synchronized time continuously to the system clocks and
devices.
Transmitter with an external antenna: transmits (broadcasts) synchronized time to the system clocks and devices
from the 39th to the 6th minute of the next hour and changes to a standby mode during the 7th to the 38th minute of
the hour (standard broadcast schedule). During initial power-up, the Transmitter transmits a signal for 8 consecutive
hours. After the 8 hour power-up period, the Transmitter reverts to its timed transmit schedule. Power-cycling a
Transmitter will set it into an 8 hour continuous transmit schedule.
• Any damage to the clock due to improper wiring voids the warranty. It is at Primex discretion as to whether damage
to the clock was caused by improper wiring.
