Timing Diagram
Mode Of Operation
• "Delay on make / Delay on break"
• Ideal for use in compressor staging
and to stagger-start multiple rooftop
units. Helps to reduce power surges.
No need to wait for the 5 minute delay
typical with delay on make timers.
* Delay on make time is proportional to selected delay on
break time.
• Upon application of power, the delay on make
period begins. Once the delay is complete,
the unit energizes.
• Lockout Timer: upon application of power, the
load is energized. Upon opening thermostat
or loss of power the load is de-energized and
the delay period begins. The compressor will
not start again during the delay period.
