Do you have a question about the Intermatic PB314EK and is the answer not in the manual?

The Intermatic PB300E Series Time Controls are 24-hour electronic timer replacement/upgrade kits designed to fit and replace most PB series Intermatic and other brand mechanical or electronic timers. These kits are suitable for various applications, with two models available: the PB313EK for 120 V. 50-60 Hz clock supply voltage and the PB314EK for 240 V. 50-60 Hz clock supply voltage. The timers are completely enclosed and feature a replaceable lithium battery to retain memory for up to three years. The kit includes all necessary hardware for installation.

Function Description:

The PB300E Series timers allow users to program up to eight ON/OFF periods per day, providing automated control over connected loads. The timer features a digital display showing the current time and programming status. It includes dedicated buttons for setting the clock, programming ON/OFF times, and overriding automatic operation. An indicator LED illuminates when the timer is connected to a power source and its contacts are closed. The timer can operate in ON, AUTO, or OFF modes, selected via a dedicated button.

Important Technical Specifications:

Models: PB313EK (120 V. 50-60 Hz) and PB314EK (240 V. 50-60 Hz)
Rating: 16A Resistive, 8A FLA
Contact Configuration: Single Pole, Double Pole
Power Consumption: 8 VA
Battery Type: CR2032 (1.5V Lithium)
Battery Life: 3 Years Minimum
Number of Programming Periods: 8 On/8 Off
Minimum Interval: 1 minute
Dimensions: The timer has a front face of approximately 2.362 inches by 2.362 inches, with a depth of about 1.102 inches.
Terminals: Features .250 male quick connect terminals for load and clock supply connections. An independent clock supply is indicated.

Usage Features:

Setting Time of Day: To set or change the time, users press and hold the CLOCK key while pressing either the HOUR or MINUTE keys until the desired time is displayed. Releasing the CLOCK key sets the time. To clear the entire memory, the reset port can be used.
Programming ON/OFF Times: Pressing the TIMER key enters program mode. The display will show "1 ON -- --". Users then press HOUR and MINUTE keys to select the first ON time, followed by another press of the TIMER key to set the first OFF time. This sequence is repeated for up to eight ON/OFF times. After programming, pressing the CLOCK key and then the SELECT key repeatedly until the indicator bar is above "AUTO" returns the timer to automatic operation.
Reviewing Program: Pressing the TIMER key repeatedly allows users to review the programmed ON/OFF times. Pressing the CLOCK key returns to the time of day.
Canceling/Changing Program: To modify a specific ON or OFF time, press the TIMER key repeatedly until the desired period appears, then set the new time as described above.
Overriding Automatic Operation:
- One-time Override: Pressing the OVR. KEY will temporarily override the current program. The timer will resume automatic operation with the next opposite setpoint.
- Permanent Override: Pressing the SELECT key moves the indicator bar to the desired ON or OFF position, keeping the timer in that state until the indicator bar is repositioned above "AUTO."
Installation: The manual provides detailed instructions for replacing old timers with four 1/4 inch tabs, two clock supply leads and two 1/4 inch load tabs, or other non-Intermatic timers. It emphasizes identifying and marking leads before installation and ensuring the load is within the timer's capacity.

Maintenance Features:

Battery Replacement: The timer uses a CR2032 lithium battery, which typically lasts a minimum of three years. A "Blank Display" symptom often indicates a discharged battery, requiring replacement.
Troubleshooting: The manual includes a troubleshooting guide for common issues:
- Blank Display: Possible causes are a discharged battery or a defective timer. Corrective actions are to replace the battery or the timer.
- Timer Not Responding to Programming: This may occur if the memory is full, requiring a press of the reset port to clear memory.
- Timer Not Functioning as Programmed: This could be due to the timer being in the wrong SELECT mode, in which case the SELECT key should be pressed to move the indicator bar over to AUTO.
- Timer is ON at All Times: This indicates the timer is in ON mode or is defective. The corrective action is to adjust the mode or replace the timer.
Warranty: Intermatic Incorporated offers a one-year limited warranty, covering defects in material or workmanship. The warranty specifies conditions for repair or replacement and excludes damages from misuse, unauthorized repair, or exceeding product cost. Warranty service is available by returning the product to the dealer or mailing it to an authorized service center.
