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.
Terminal Connections
Contacts shown in "Off" position (trippers pushed inward)
"On" position (trippers pushed outward) will close contacts 3 & 4
