1. Uvod
This manual provides detailed instructions for the installation, programming, and operation of your Intermatic ET1725C Electronic 7-Day SPST Timer. This device is designed to automate the control of electrical loads with precise, up-to-the-minute scheduling. It features battery backup for power loss, up to 14 ON/OFF set points per circuit, and automatic daylight saving time corrections.
The ET1725C is an upgrade from basic mechanical time switches, offering enhanced functionality and ease of use. Its contacts can be configured as two independently operated SPST, one simultaneously operated DPST, or independently pulsed SPST for contactor and bell ringing applications. It supports multi-volt operation from 120-277 VAC, 50/60 Hz.
2. Sigurnosne informacije
UPOZORENJE: Risk of electrical shock. More than one disconnect switch may be required to de-energize the equipment before servicing. Always disconnect power at the circuit breaker or fuse box before installing or servicing this timer.
Use 10-18 gauge copper conductors rated for at least 75°C (167°F) for all connections.

These diagrams illustrate connections for Timer Power, Line, Neutral, and Load terminals.
- ET1705-120 VAC-SPST: Connect Line and Neutral to Timer Power. Connect Line to terminal 1 and Load to terminal 2. Install jumper between terminals 3 and 4 if load voltage i ulazna voltage su isti.
- ET1715-SPDT (Load Switching): Similar to ET1705, but with additional load connections for switching.
- ET1725-240 VAC-DPST: Connect L1 and L2 to Timer Power. Connect L1 to terminal 1 and L2 to terminal 3. Connect Load to terminals 2 and 4. Configure jumper to "SIM" for simultaneous operation.
- ET1725-2x SPST: For two independent SPST loads. Connect L1/Neutral to Timer Power. Connect L1 to terminal 1 and L2/Neutral to terminal 3. Connect Load 1 to terminal 2 and Load 2 to terminal 4.
- ET1725-Pulse 2x SPST (Bell Ringing): For pulsed applications. Configure jumper to "PUL".
4. Podešavanje i programiranje
The ET1725C allows for flexible programming with up to 14 ON/OFF set points per circuit. The timer automatically adjusts for daylight saving time.
