Programmable Timers provide automatic, timed operation of
HVAC and lighting equipment. Closely spaced timing intervals
operate equipment only as needed. Timers have either a
synchronous clock motor or a regulated quartz oscillator for
accurate timing. Timers are flush mounted on panel door or
mounted on an accessory rail inside the panel.
Trippers:
24-hour model - 4 pair
7-day model - 9 pair
Approvals:
UL Listed
CSA Certified
Dimensions In Inches (Millimeters):
/i‘, Accessory rail mounted standard; optional flush mounting (panel door)
available.
,/& The program spacing (slots) in the outer rim allows interval settings of 15
minutes (24-hour Timer) or 1 hour (7-day Timer). However. tripper
thickness requires a minimum interval setting of 30 minutes or 3 hours for
the 24-hour or 7-day Timer, rcspcctively.

The 7-day Programmable Timer dials are subdivided into the
seven days of the week, and AM and PM, for each day in onehour increments. The 24-hour model dials are subdivided into
AM and PM in 15-minute increments, The switching time
from ON to OFF or OFF to ON is determined by the location
on the dial edge of the on/off trippers. The on/off indicator
(upper right from dial) allows visual checking of the automatic
tripping status as well as manually tripping the timer contacts.
Optional standby battery (quartz models only) maintains
correct programming time for up to 50 hours in case of power
failure.

In a typical application, the Programmable Timer starts a fan
system for day operation (e.g., ON at 7:00 AM) and then later
returns the fan to the night mode (e.g., OFF at 6:00 PM). The
second switch will control the EP relay to keep the damper
shut during night operation.

Programming
Setting
The Timers are programmed as follows:
To set the Timer, remove clear plastic dust cover and turn knob
in center (minute hand) clockwise to the correct time and day
of the week (7-day models).
Remove clear plastic dust cover.
Insert a green tripper, labeled 1, into the slot of the outer
rim at each time the equipment is to turn ON.
Insert a red tripper, labeled 0, into the slot of the outer rim
at each time the equipment is to turn OFF.
NOTE: Always use red and green trippers in pairs.
Replace dust cover.
N
imer gears only turn the center knob
clockwise. Do NOT turn outer rim by hand.
NOTE: For proper Timer operation, the arrow on the dial
between one and two o’clock must point to the
correct time and to the day of the week (7-day
models) on the outer rim.
When changing from Daylight Savings Time to Standard
Time, it may be easier to remove power from Timer motor for
one hour (7-day models) than to reset the time.
