Installation and Setup Instructions
WARNING
Risk of Fire or Electric Shock
• Disconnect power at the circuit breaker(s) or disconnect switch(es) before installing or servicing.
• More than one circuit breaker or disconnect switch may be required to de-energize the equipment before servicing.
• For plastic enclosures, bonding between conduit connections is not automatic and must be provided as part of the installation.
• Installation and/or wiring must be in accordance with National and Local Electrical Code requirements.
• Use #14-#8 AWG wires, rated at least 105°C - COPPER conductors ONLY.
• If the power disconnect point is out of sight, lock it in the OFF position and tag it to prevent unexpected application power.
• Make sure there is no wire insulation under the terminal plate on the time switch connector. Firmly tighten terminal screws.
• For outdoor locations or wet locations (rain-tight), conduit hubs that comply with requirements of the UL514B (standard for fitting conduit and
outlet boxes) are to be used.
• Do not remove insulator that is covering terminals.
• Do NOT exceed maximum current carrying capacity.
• KEEP DOOR CLOSED AT ALL TIMES when not servicing.
NOTICE
• Do NOT touch circuit board components, contact can create a static discharge, which can damage these electronic components.
Description
This document explains the setup and configuration of the Intermatic ET2825 2-Circuit
Electronic Astronomic 365/7-Day Time Switch. The ET2825 time switch automatically
switches loads according to the entered weekly schedule. The time switch can support up
to 48 fixed ON and 48 fixed OFF events (96 total) and up to 4 Astro events. Each fixed
event can be applied to any combination of circuits and days.
The time switch features an LCD and panel-mounted control buttons to set, review, and
monitor the time switch functions, including setting date and time, schedule creation,
enabling or disabling Daylight Saving Time (DST) and configuring DST switchover dates.
Follow these instructions to complete the installation and programming of the ET2825 time
switch.
Federal Communications Commission (FCC) Notice for ET2000 Series Time Switches
This device complies with part 15 of the FCC rules. Operation of this device is subject to the following two conditions: (1) This device
may not cause harmful interference, and (2) This device must accept any interference, including interference that may cause
undesired operation. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses and radiates radio frequency energy and, if
not installed and used in accordance with instructions, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference that requires the user to correct at his or her own expense.

- Page 2 Installation Snap out catch Tilt top forward Follow these instructions to install the time switch. Open the time switch enclosure door. Remove and retain the screw that secures the plastic insulator. Lift the left side of the plastic insulator and pivot away to expose the terminal strip. Press the latch at the top of the enclosure and pull out the mechanism from the enclosure.

- Page 4 Initial Setup The following sections provide instructions for the initial setup of the time switch. Setting The Output Configuration The time switch output configuration enables users to control multiple loads simultaneously (SIM), independently (IND), or with a 2-second pulse (PUL). Output circuits are configured in pairs. In PUL mode, an ON event or manual override, causes circuit #1 to turn ON for two seconds, then OFF.
- Page 5 Enable/Disable Daylight Saving Time and Setting Daylight Saving Time Rule Configure the time switch to automatically adjust for Daylight Saving Time (DST). If DST does not apply to your region, disable the option as directed in this procedure. Follow this procedure to enable/disable the Daylight Saving Time feature, and if applicable, set the DST rule.
- Page 6 Setting Astro Zone and Time Zone The astronomic feature of this time switch provides a sunset ON event and a sunup OFF event for each circuit (see “Setting Astronomical ON/OFF Events”). These ON and OFF events automatically adjust to the actual change in sunset and sunup times in the geographical location (Astro zone) that is set in the following procedure.
- Page 7 Setting Sunup and Sunset Offset Times from Astronomic Sunup and Sunset Times Normally, the time switch’s sunup and sunset times match the actual occurrence of sunup and sunset (astronomic sunup and sunset times). In some cases it is desirable to change the time switch’s sunrise and sunset times so circuits turn on or off either before or after an actual sunup or sunset.
- Page 8 Setting Astronomic On/Off Events Access the Astro Events screen to configure Astronomic ON/OFF events for each individual circuit. For each circuit one Astronomic ON event (at sunset) and/or one Astronomic OFF event (at sunup) can be enabled for selected days of the week. Follow this procedure to set Astro ON/ OFF Events (if no astronomic events need to be set press MODE to move to the next mode selection).
- Page 9 Setting Fixed Timed Events Access the Fixed ON/OFF screen to set fixed switching times. Odd-numbered events are for ON switching and even-numbered events are for OFF switching. These events can be enabled for selected days of the week. Follow these steps to set fixed time events (if no fixed events need to be set press MODE to move to the next mode selection): Press MODE to advance until SET FIXED ON/OFF EVENTS and ON@ icons appear on the display (if this selection is not already active.
- Page 10 Setting Holidays There are 50 Holiday blocks that can be programmed along with a single schedule for each block. For each block there will be a start date and an end date. Within each block one scheduled “on” event and one “off” event can be programmed. Holidays are recognized by an H on the display.
- Page 11 Clearing Time Switch Memory During a “Clear Time Switch Memory” operation, the time switch resets all programmed settings to their factory default value. The following occurs: • After a brief period of time the time switch model number appears, followed by the USB Boot Loader version, EE Boot Loader version, the firmware revision and finally the Reset Reason Code.
