Time Clock

Setting the Time Clock
The time clock must be programmed for the unit to operate. If
not programmed, the unit may not run in the correct occupied/
unoccupied state until timing instructions are received from the
time clock.
Note: Power must be supplied to the unit for the time clock to
be set.
The following procedure covers:
• setting the time format
• setting the current time and day
• setting the program ON / OFF settings (events)
• pre set program selections
• deleting programs
• daylight savings setting
• overriding programs (manually)
The time clock is located behind the access door of a unit
ventilator.

programming during Daylight Savings Time, one hour
should be subtracted from times needed (see

For example, if the Daylight Savings Time is 2:30, the time
setting for the clock should be 1:30.
