The TAC1 Series was designed to delay the operation of a compressor relay. It eliminates the possibility of relay chatter due to half-wave failure of the output. It connects in series with the load relay coil and provides a delay on make time delay each time input voltage is applied. It can be used for random start, anti-short cycling, sequencing, and many other applications. It is an excellent choice for all air conditioning and refrigeration equipment.
UL Approved for Air Conditioning & Refrigeration Equipment
The T2D Series provides protection against short cycling of compressors and other motors. At the end of each operation, a lockout delay prevents restarting the compressor or motor until the delay is completed. 24 V AC models can be used with thermostats that include a cooling anticipator resistor. Can be connected in series with the load for delay on make operation.
Lockout Delay - Prevents Rapid Recycling of Compressor
Random Start Delay - Helps Prevent Low Voltage Starting
Delay on Make Timer - Optional Two Terminal Series Connection
Totally Solid State 1 A Output
24 V AC - 230 V AC in 2 Ranges
Bypass Timer
TAC4 Series (Interval)
HVAC/R Timer
The TAC4 is a bypass timer that provides a closure across the low pressure switch during compressor startup. Its time delay circuit is totally solid state including the normally closed output. The molded housing with encapsulation, the single hole mounting, and 0.25 in. (6.35 mm) termination makes the TAC4 easy to use, rugged, and reliable.

Redundant Circuitry Eliminates Chatter Problems
Lockout Timer
TA Series
HVAC/R Timer
The TA Series prevents rapid recycling of a compressor. A lockout delay is started when the thermostat opens, or input voltage is lost. Eliminates tripped circuit breakers or blown fuses caused by a locked rotor during short cycling. The TA will not allow the compressor to start when the line voltage is low. Chatter of the compressor relay is eliminated. Because of the fast initiate time, bounce of the thermostat will not be transmitted to the compressor relay coil. A 30 second delay provides anti-reversing protection for scroll compressors.

Lockout Timer
TL Series
HVAC/R Timer
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).

CT Series
HVAC/R Timer
The CT Series combines a delay on make and delay on break time delay into one unit and may be used to control fan delays in heating and/or cooling equipment. The CT includes bypass circuitry to allow it to operate with cooling anticipators ≥ 3000 ohms. It is designed to operate in 24 V AC control circuits. Several CT modules may be combined to provide sequencing ON of any number of loads and sequencing OFF of the same loads, such as electric heating elements.
