DescriptionDescription
The TL Series provides protection against short cycling of a compressor. At the end of each operation, or
whenever power is lost, a lockout delay is initiated. This lockout delay prevents restarting of the compressor
until the head pressure has equalized. Compressor relay chatter due to thermostat bounce is eliminated by
use of optional one second delay on make. The TL Series should not be used with cooling anticipator resistors
or solid state switches. (See the TA Series).

interrupted, the output opens and remains open for
the lockout time delay. During this lockout time delay

*Power must be applied for at least 15 s to achieve a full lockout delay.
Less than 15 s will result in proportionally shorter delay periods.
NOTE: Cooling anticipator resistor or leakage may cause erratic
operation. See TA Series for use with 24 V AC systems that include
anticipator resistors or use solid state switches.
