APPLICATIONS
The FM/1 series of time switches are designed for control of
heating, ventilating, air conditioning, refrigeration, lighting,
security, circulating pumps, spas or any electrical load requir-
ing 24-hour or 7-day scheduling.
WIRING
Verify input voltage stated on back of unit. Use 1/4” quick con-
nects and make connections in accordance with the wiring
diagram shown and applicable code requirements. When
using 24V units, it is important to use transformers that will
supply the required 24 volts AC to terminals 1 & 2.
MOUNTING
The standard FM/1 units can be flush mounted (mounting kit
with screws available) or surface mounted inside a panel. A
printed circuit board mounting base is also available. An
indoor or outdoor enclosure is available for stand-alone
mounting. In addition, unit is also available in DIN housing for
flush or surface mounting (see MIL72, Digi 20 or Digi 42 data
sheets). Optional clear plastic dust cover is available.
Terminal Connections
Contacts shown in “Off” position (trippers pushed inward)
“On” position (trippers pushed outward) will close contacts 3 & 4
