*1. The total error including the repeat accuracy, setting error, variation due to voltage change, and variation due to
temperature change is ±0.01% ±0.05 s max.
*2. The time given for memory protection is the calculated time of when power is not being supplied (including during
storage) at an ambient temperature of 25°C. The timer functions and set program are backed up by a lithium battery
that is built into the Time Switch. These will be lost if the life of the battery expires. If the lithium battery is replaced
(if the PCB is replaced), the stored contents will also be lost.

(H5S-W[]2)
Yearly 2-circuit Models
(H5S-Y[]2)
Yearly 4-circuit Models
(H5S-Y[]4)
Weekly timer
operation

Controls the output according to the set time of ON and OFF.
Min. setting unit: 1 min
Multiple-day operation also possible.

Weekly pulse-output
operation

Output turns ON for a fixed period (pulse width) at the set ON time.
Pulse width: 1 to 59 s (in 1-s increments), or 1 to 60 min (in 1-min increments)
The pulse width can be set for each step.

Weekly cyclic
operation

Repeatedly turns ON and OFF during the period from the cyclic start time to the stop time.
Independent ON- and OFF-time settings are possible.
Min. setting unit: 1 min (The ON time width and OFF time width can each be set to between
1 minute and 11 hours 59 minutes.)
(The timer operation repeatedly turns the signal ON and OFF for the time widths specified by
the ON time and OFF time during the period from the day of the week and time that are set
for the cyclic start time to the day of the week and time that are set for the stop time.)

Yearly timer operation Adds a yearly timer operation to the weekly timer program.
For details, refer to About Yearly Programs on Data Sheet.
Yearly pulse-output
operation
Adds a yearly pulse-output operation to the weekly
pulse-output program.
For details, refer to About Yearly Programs on Data Sheet.
Temporary holiday
setting
Sets temporary holidays (non-operating days) without having to revise the existing program.
For details, refer to Setting Temporary Holidays (Weekly) and Setting Temporary Holidays
(Yearly) on Data Sheet.
Day override operation Executes the operation for
one day temporarily on
another day in the 7-day
period starting from the
current day.
For details, refer to Day
Override Operation on Data
Sheet.
Program check Consecutively displays the days and times when the output is set to turn ON and OFF over
the course of one week in the sequence in which the Time Switch is to operate.
For details, refer to Program Check Function on Data Sheet.
Checking the settings Consecutively displays the times when the output is set to turn ON and OFF for one day in
the sequence in which the Time Switch is to operate.
For details, refer to Checking the Settings on Data Sheet.
Forced ON/OFF
operation
Allows the output to be forcibly turned ON/OFF by the Output ON/OFF Switch regardless of
the control output setting.
Override and automatic
return operation
Allows the control output to be maintained in the ON (or OFF) state until the next OFF (or
ON) time. This operation is controlled by using the Output ON/OFF Switch and Write Key.
When completed, the Time Switch automatically resumes the previously set operation.
For details, refer to Override and Automatic Return Operation on Data Sheet.
Summertime (DST)
adjustment
Switches the current time from “current time” to “current time + 1 h” for daylight savings
time. Yearly models also offer automatic switching to daylight savings time.
For details, refer to Manual Summer Time (DST) Adjustment on Data Sheet.
Time counter/total
counter display
Displays the total elapsed time and total count of external
input. It also displays a warning when a set value is entered.
For details, refer to Time Counter/Total Counter Display (F2,
F3, F4) on Data Sheet.
Time adjustment input Allows the time to be set to 00 min 00 s at the same time as
an external input is applied.
For details, refer to Time Adjustment Input Function (F2) on
Data Sheet.
Manual operation on
recovery from power
failure
Allows the output state to be specified following recovery
from a power failure.
For details, refer to Manual Operation on Recovery from
Power Failure (F2) on Data Sheet.
Bank switching Allows two groups (banks) of
programs to be registered and
switched by external input.
For details, refer to Bank
Switching (F2) on Data Sheet.
Season switching Allows weekly programs to be automatically switched in
response to seasons throughout the year.
For details, refer to Season Switching/Period of Season
(F8/F9) on Data Sheet.
Power OFF settings Allows the display to remain lit even when the power is turned OFF, and settings to be made
for all functions except Override and Automatic Return Operation.
The display illumination will turn OFF when there has been no operation for 2 min. The
display will light again when any key other than a slide switch is pressed for at least 1 s.
No output will be generated.
