CP-U49A Multi-Voltage DPDT Time Control
Product Brief
The CP-U49A is a versatile, electro-mechanical time control that can be configured for multiple supply voltages: 120VAC, 208VAC, 240VAC, and 277VAC. Voltage selection is made via a dip switch. This time control is housed in a NEMA 3R indoor and outdoor enclosure. It is designed for controlling lighting, heating, air conditioning, pumps, motors, or general electrical circuits in residential, commercial, industrial, and agricultural settings. The switch rating is DPDT.

Input Voltage Dip Switch Setting
Caution: Dip switch voltage selection must be finalized prior to applying power to the time control. Do not apply power before setting the correct input voltage using the DIP switch. Determine the input voltage and set the dip switch according to the diagram below.
Diagram showing DIP switch configurations for 120VAC, 208-240VAC, and 277VAC.
NOTE: The factory default setting for the DIP switch is for 277VAC input voltage.
Caution: Do not check circuits by sparking wires to terminals, as this may damage the timer.
If loads are connected to both NC (Normally Closed) and NO (Normally Open) contactors, both contacts are derated to 67% of the above values.
LED Indicators Function
- Power LED (Red): Illuminates when power is applied to the timer.
- Status LED (Green): Illuminates when power is applied to the loads.
Installation
Warning: Before wiring or service, power to this time control and the equipment it controls must be turned off. Turning off the time control only will not prevent a shock hazard. Installation should be performed by a licensed electrician only. Read all instructions carefully before installing this product.
Choose appropriate knockouts (KO's) according to the cable, wire size, and direction. Optional external mounting tabs are provided.

Remove the protective cover panel in the time control housing by pressing the clip at the bottom of the cover panel.
DIP Switch Configuration
WARNING: Failure to properly configure the DIP switch will result in damage to the unit and void the warranty. Before installing and wiring the time control, the proper configuration must be selected as per the DIP switch diagram.
Operating Instructions
Once the Time Control is installed and power is applied, the timer's dial will rotate clockwise, maintaining time. The pointer on the dial indicates the current time.
- Locate the segments around the outer edge of the timer's dial. Each segment represents 15 minutes and can be pushed down and away from the edge of the dial (using a small slotted screwdriver or similar instrument) to set the load "ON" period. Segments that have been pushed down can be pushed back up by hand. Ensure all segments are pushed up before programming. To set a time period for the device to be ON, push down all segments that fall within that time period. For example, to turn a device ON from 10 PM to 2 AM, push down the segments for 10 PM and 2 AM, and all segments in between. You may need to turn the dial clockwise to access the desired segments.
- Rotate the timer's dial clockwise until the pointer indicates the current time of day. Note: Nighttime hours (6:00 PM to 6:00 AM) are highlighted with a colored background.
- Set the override switch to the AUTO position.
- To manually override the timer program and control the output load:
- Set the override switch to OFF (center position) to turn the load OFF.
- Set the override switch to ON (bottom position) to turn the load ON.
- This is a Time Control and should not be used for power disconnect. Turn power off at the main panel before servicing this switch or the equipment it controls.
- In case of power failure, reset the time of day as explained in step 2.
Override Switch Function
- AUTO: Programs are active; the timer functions according to the scheduled program.
- OFF: Always off; the timer is in override "OFF" mode until the switch is set to ON or AUTO.
- ON: Always on; the load remains "ON" until the override switch is reset to OFF or AUTO.
