Jewenwils Outdoor Digital Timer Box

Product Illustration

The Jewenwils Outdoor Digital Timer Box is depicted as a rectangular enclosure with a hinged front cover. When opened, the interior reveals a central timer module with a digital display and control buttons. Below the timer module are two indicator lights: a Load Indicator and a Power Indicator. On the sides and bottom of the enclosure, there are circular knockouts for electrical conduit connections. The overall design suggests a robust, weather-resistant build suitable for outdoor electrical control.

Installation Instructions

1. Read Important Safety Information below before beginning installation.
2. Open the outer cover by pressing the clip.
3. Remove the interior protective cover by removing the two screws holding the cover in place. (Refer to Figure 1, which shows the interior protective cover being removed from the timer box, indicated by two arrows pointing away from the cover.)
4. Select the knockouts to be used. If using the 1/2" knockout, carefully cut off the inner ring of the rubber plug with a knife. (Refer to Figure 2, which illustrates a tool cutting the inner ring of a knockout plug.) If using the 3/4" knockout, remove the entire rubber plug. (Refer to Figure 3, which shows a knockout plug being completely removed from the enclosure.)
5. Place and mark the timer box in the desired mounting position. Install two screws at the mark and partially drive into place. Attach the Timer Box by placing screws over keyholes, then tighten screws.
6. Remove the screw to demount the motherboard. (Refer to Figure 4, which depicts a screw being removed from the top right of the timer module, allowing the motherboard to be demounted.)
7. Wire in accordance with national and local codes (see wiring diagrams below). Use copper wire AWG 8-18 suitable for 90°C (194 °F). Tighten all connections to a minimum of 10.6 lb. in. torque.
8. Grounding: Connect all grounding wires to the grounding lug at the bottom of the enclosure.
9. Reassemble the motherboard and interior protection cover.
10. Close the outer cover.

Important Safety Information

⚠️ WARNING: Risk of Fire or Electric Shock. Read instructions thoroughly before installation and preserve for future reference.

Disconnect power at the circuit breaker and test if power is off before installing (or servicing) the Timer Box (more than one circuit breaker or disconnect switch may be required to fully disconnect power).

Wiring must be in accordance with all national and local electrical code requirements. Inspect all terminals and wires with a voltage meter before touching. The maximum total load to be controlled must not exceed the Timer Box capacity.

The Timer Box enclosure does not provide grounding between conduit connectors. When metallic conduit is used, you must also install grounding type bushings and jumper wires in accordance with National Electrical Code (NEC) requirements.

Timer Box Terminal Designations

A diagram of the Timer Box terminals shows a layout with two switches, S1 and S2, and various connection points. The terminals are labeled as follows:

• T: Timer
• L: Line
• N: Neutral
• COM1: Common Terminal 1
• NO1: Normally Open 1 (Isolated Contact)
• COM2: Common Terminal 2
• NO2: Normally Open 2 (Isolated Contact)

Below the diagram, the legend defines the terms:

• L = Line
• N = Neutral
• NO = Normally Open
• COM = Common Terminal
• J = Jumper Wire
• T = Timer

Timer Box Typical Application Wiring Diagrams

Note: The Timer Box is capable of being configured for 120 VAC, 240VAC, or 277VAC.

*J1 & J2 are jumper wires for the timer power supply.

120VAC Application Controlling One 120VAC Load

This diagram illustrates the wiring for a single 120VAC load. The L (Line) and N (Neutral) inputs connect to the timer. A jumper wire (J1) connects the Neutral terminal to COM1. The load is connected between NO1 and the Neutral line. The timer's power supply is derived from the 120VAC input, with N connected to the timer's N and L connected to the timer's L. The load is controlled via the NO1 terminal.

120VAC Application Controlling Two 120VAC Loads

This diagram shows the wiring for two 120VAC loads. Similar to the single load setup, L and N inputs connect to the timer, and a jumper wire (J1) connects Neutral to COM1. Load 1 is connected between NO1 and Neutral. Load 2 is connected between NO2 and Neutral. An additional wire (A) connects COM1 to COM2. Note: The wire connecting COM1 with COM2 should use the same gauge as the load wire.

240VAC Application Controlling One 240VAC Load

This diagram details wiring for a single 240VAC load. L1 and L2 inputs connect to the timer. A jumper wire (J1) connects L1 to COM1, and another jumper wire (J2) connects L2 to COM2. The 240VAC load is connected between NO1 and NO2. The timer's power supply is derived from L1 and L2.

277VAC Application Controlling Two 277VAC Loads

This diagram shows wiring for two 277VAC loads. L and N inputs connect to the timer. A jumper wire (J1) connects Neutral to COM1. Load 1 is connected between NO1 and Neutral. Load 2 is connected between NO2 and Neutral. An additional wire (A) connects COM1 to COM2. Note: The wire connecting COM1 with COM2 should use the same gauge as the load wire.

Hot Water Heater Typical Wiring Diagram

This diagram shows a typical wiring setup for a hot water heater. A 120VAC hot water tank is connected to a circuit breaker box. The Timer Box is integrated into the circuit. The 120VAC lines from the circuit breaker (L1 and L2, forming a 240VAC dual-phase supply) connect to the Timer Box. Jumper wires J1 and J2 are used within the timer box to supply power to the timer module. The hot water heater's 120VAC lines are then routed through the timer's NO1 and NO2 terminals, allowing the timer to control the power to the hot water tank. The diagram indicates both 120VAC and 240VAC connections from the circuit breaker to the timer and the hot water tank.

IMPORTANT: Please refer to the INSTALLATION INSTRUCTION SHEET. The Timer Box must be installed before programming.

Operating Instruction

1. Reset

Before programming, all settings should be reset. Use a paper clip or ball pen to poke the reset hole identified by "R" under the "R/RECALL" button. Refer to Figure 1 (for operating instructions), which shows a digital display initially showing "88:88:88" with all days of the week (MO TU WE TH FR SA SU) and "PROG AUTO" indicators. After a few seconds, the display resets to "00:00" with only "MO" and "AUTO OFF" visible, indicating a successful reset.

5. Switching Mode Indication

The actual mode is shown on the display as "ON", "AUTO ON", "OFF", or "AUTO OFF" together with the time of day. Press the "ON/AUTO/OFF" button to adjust to the desired setting mode.

6. Manual Override Setting

As an independent programming, it is possible to advance to the next switching command at any time by continually pressing the "MANUAL" button, as shown by the sequence: AUTO OFF → ON → AUTO ON → OFF.

• ON = Always ON;
• OFF = Always OFF;
• AUTO ON = Timer is ON currently and ON/OFF program is activated.
• AUTO OFF = Timer is OFF currently and ON/OFF program is activated.

7. Daylight Saving Time (DST)

Press and hold the "CLOCK" button for 3 seconds to advance the current time by 1 hour; a "+1h" icon will appear on the display. Press and hold the "CLOCK" button for 3 seconds again to decrease 1 hour, and the "+1h" icon will disappear. Refer to Figure 8, which shows a display initially set to "TH 8:00" and then, after pressing the CLOCK button, changing to "TH 9:00" with a "+1h" indicator, illustrating the DST adjustment.

8. Power Back-up Feature

In the event of a power outage, the timer will retain its settings for an estimated 3 months if the power backup is fully charged.
