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 affect-
ed 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.
2. Disconnect supply power prior to installation to
prevent electrical shock.
3. Install in accordance with all applicable
National and Local electrical code requirements.
MOUNTING OPTIONS:
The standard FM1D models may be surface
mounted inside a panel or flush mounted with FM-FU
mounting kit, available from Intermatic. Indoor NEMA
1, and outdoor NEMA 3R enclosures are available
for stand-alone mounting. Consult Intermatic catalog
or price sheet for various options.
FM1D20A and FM1D50A models are available
with screw terminals and din rail mounting.
FM1D20E and FM1D50E models are available for
flush mounting and include a protective housing.
All models include a clear plastic snap on dust
cover.
