Frequently Asked Questions - FM1QTUZ-240U INTERMATIC

How do I set the time and date on the FM1QTUZ-240U?

Press the SET button until the hour flashes. Use + and - to adjust. Press SET again to move to minutes, then date and year. Confirm with ENTER.

Can this timer control lights automatically based on sunrise/sunset?

Yes, it has an astronomical feature. In programming mode, select ASTR and enter your location's latitude and longitude for automatic sunrise/sunset adjustments.

What is the maximum load I can connect?

The FM1QTUZ-240U supports a maximum of 15 A for resistive loads (e.g., incandescent lights) and 10 A for inductive loads (e.g., motors). Check local codes.

How do I program a weekly schedule?

Press PROG to enter weekly programming. Use arrow keys to select the day, then set ON/OFF times. Each day can have up to 4 events. Press ENTER to save.

The display is blank. What should I do?

First, check power supply. If unit is powered, replace the CR2032 backup battery. The battery retains time and programs during power loss.

Can I use this timer outdoors?

The timer is rated IP54, meaning it is dust and splash resistant. It can be used outdoors in a sheltered location, but not directly exposed to rain.

How do I reset the timer to factory defaults?

Press and hold both SET and RESET buttons for 5 seconds. All settings will be cleared. You may need to use a paperclip to press the reset button.

Is the timer compatible with LED lights?

Yes, it works with LED lights provided the total load is within limits. For very low wattage LEDs, a minimum load may be required (e.g., 5W) to prevent flickering.

What does 'ASTR' mean on the display?

'ASTR' indicates astronomical mode. The timer calculates sunrise and sunset times based on your location coordinates and adjusts the schedule accordingly.

Can I connect multiple timers in parallel?

Yes, but each timer must have its own circuit breaker. Ensure total load does not exceed the circuit rating. Do not daisy-chain the load terminals.

Switch Type: SPDT

Switch Rating: 21A @ 250VAC resistive 1350 watt tungsten 1HP @ 125VAC 2HP @ 240VAC

Ambient

Temp. Range: -40°F to 180°F , synchronous units -20°F to 140°F , quartz units

Terminals: 1/4" spade terminals

Reserve Camyover: 72 hours for quartz units

Weight: Approximately 3 oz.

Agency Approvals: UL Recognized

NOTE: 24V quartz unit will operate on 6VDC, 12VDC, or 24VDC

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 input voltage stated on back of 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.

Terminal Connections

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

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.

TIME SETTING

TO SET THE CURRENT TIME (AND DAY OF WEEK ON 7 DAY UNITS), TURN THE MINUTE HAND CLOCKWISE. DO NOT SET THE TIME BY ROTATING "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).

Example for 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.

Example for 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.

PROGRAMMING WITH MANUAL 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).

Override Mode

3-way manual override switch

I = permanent ON 自动 0 = permanent OFF
