One Channel Electronic Time Switch

The FM1D Series Timers are compact electronic 24 hour/ 7 day time switch module with heavy duty relay contacts for switching low or line voltage loads. Applicable for time of day control of pumps, fans, heaters, HVAC control circuits, lighting, machinery and many other types of commercial, industrial, and agricultural equipment.

The FM1D Series features large keys with unique “circular pattern” for easy programming, an easy-to-read LCD display and capacitor backup

to retain program memory during power outages.

INSTALLATION & WIRING:

Note: Although the FM1D models contain some degree of spike and electrical noise protection, as with all electronic devices, these units can be affected by electrical noise. Therefore, it is recommended that they be powered from a voltage source that has no switching devices or inductive loads connected.

1. Check the input and output ratings marked on the unit to make sure this product is suitable for your supply voltage, load, and application.
