Display Does
• Make sure flat cable is properly plugged into the
Not Light
rear of the logic module. Refer to “Re-installing
logic module” in Special Instructions. If connec-
tor will not install easily, check for bent pins.
• On multi-volt models make sure the voltage
selector jumper is correctly installed and that
matching voltage is present at timer power
terminals. On 24V models make sure 24VAC
is present at timer power terminals.
Loads Not
• Check wiring. Note the load contacts are
Switching
isolated to allow you to switch loads with a
voltage different than the timer power. You may
have forgotten to add the appropriate connec-
tions required to power the load contacts. See
wiring examples.
• Check to ensure all breakers or disconnects
have been reset.
• Make sure load switches are in
Enable
position
for automatic switching.
• After a power interruption all loads will be Off
and will “catch up” to the present programmed
state as of midnight of the present day.
Schedules that turn On one day, then Off one
or more days later, need a redundant switch On
time at 12:00 AM. See “Load Controls” for
details.
• Make sure the
SET/RUN
switch is set to
RUN.
• Note that override intervals are not ended by
scheduled Off events. Override intervals may
only be ended by timing out, a power interrup-
tion, or by pressing the
ON/OFF
key.
• Review
SETUP
to see if timer could be following
a holiday program with no scheduled activity.

WARNING:
Connect 24 VAC 60 Hz only to 24V timer power
terminals.
NOTE:
To enable switching loads of a voltage different than the timer
power voltage, the outputs from this timer are isolated relay contacts. You
need to connect a source of power to the common (COM) terminals as
shown above. Do not mix solid and stranded wires under the same
terminal.
