Bird X Peller FM/1 Series Time Switches Instruction Manual
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 requiring 24-hour or 7-day scheduling.
WIRING
Verify the input voltage stated on the back of the unit. Use 1/4” quick connects 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, the unit is also available in DIN housing for flush or surface mounting (see MIL72, Digi 20, or Digi 42 datasheets). An optional clear plastic dust cover is available.

TIME SETTING
TO SET THE CURRENT TIME (AND DAY OF THE WEEK ON 7-DAY UNITS), TURN THE MINUTE HAND CLOCKWISE. DO NOT SET THE TIME BY ROTATING THE “OUTER” DIAL.
Turn the minute hand clockwise until the day of the week (7-day timer) and the time of day on the outer dial is aligned with the triangle marker on the inner dial (two o’clock position). For example for a 7-day program dial Monday 10:30 AM. Turn the minute hand clockwise until Monday 10:30 AM is aligned with the triangle on the inner dial. The hour and minute hand will show exactly 10:30. For Example for a 24-hour program dial 10:30 AM. Turn the minute hand clockwise until 10:30 AM is aligned with the triangle on the inner dial. The hour and the minute dial will show exactly 10:30.
PROGRAMMING
7-Day (SW, QRW Models)
The weekly program dial reflects the seven days of the week and AM/PM imprints for each day. The time switch is programmed by pushing the captive trippers to the outer ring position for the entire period that the load is to be turned “ON”, i.e., two hours for each tripper on the 7-Day dial. When the tripper is pushed to the inside, the switch is in the “OFF” position.
24-Hour (ST, QRT Models)
The 24-Hour dial has quarter-hour divisions and AM/PM indications. The time switch is programmed by pushing the captive trippers to the outer ring position for the entire period that the load is to be turned “ON”, i.e., fifteen minutes for each tripper on the 24-Hour dial. When the tripper is pushed to the inside, the switch is in the “OFF” position.
OVERRIDE SWITCH
AUTOMATIC MODE
In order to operate the time switch module in the automatic mode, the manual switch must be in the center position (automatic) – see diagram.
MANUAL MODE
With the manual switch selector lever, the selected programs can be overridden. In the lower position, marked “O”, terminals 3 and 5 are permanently closed. In the upper position, marked “I”, terminals 3 and 4 are permanently closed (see diagram).
