SuperPro CHRONO-B1 Analogue Interval Timer

SuperPro CHRONO-B1 is an interval timer

• Input voltage / Max. amperage: 230V / 10Amps
• Max. output amperage: 10Amps at 230V AC
• Range in On Time mode: from 15 seconds to 5 hours
• Range in Off Time mode: from 15 seconds to 13 hours
• Timing accuracy: +/-5% of the set time
• Weight / Dimensions: <0.5 kg / 78*90*135 mm

The built-in photocell determines 3 operating modes - (1) "day" - during the light period, (2) "night" - during the dark period, or (3) continuous - regardless of lighting.
The time intervals are set using the two rotary knobs. Three illuminated indicators show the current operating mode.

Installation:

• Plug CHRONO-B1 into a standard 220V outlet. For permanent mounting, the lug at the top of the housing can be used.
• Plug in the device (or devices) whose switching will be controlled. Make sure the maximum current (10 A, or about 2200W) is not exceeded. If you need to control device(s) with higher power, use a relay.

Operating mode:

• Before using the timer, you must set the operating mode ("day", "night" or continuous). The built-in photocell (on the left of the housing) switches modes when the lighting changes. Select the mode using the two rotary knobs. The timer must be connected to the mains.
• To select "DAY" mode: turn both knobs fully to the left. After a few seconds, the light indicators will start flashing, then only the DAY indicator will remain lit.
• To select "NIGHT" mode: turn both knobs fully to the right. After a few seconds, the light indicators will start flashing, then only the NIGHT indicator will remain lit.
• To select CONTINUOUS mode: turn the left knob fully to the left and the right knob fully to the right. After a few seconds, the light indicators will start flashing, then both DAY and NIGHT indicators will remain lit.

Setting time intervals:

• Once you have set the operating mode, you can adjust the rotary knobs to the desired time intervals. Observe the device's operation during the first few cycles and fine-tune it as needed.

Questions and answers:

How do I know whether the photocell is working?

• The photocell operates with a 30-second delay so that it is not activated by accidental brightening or darkening. The green "DAYTIME" indicator on the right side of the housing will light up when the photocell is in day mode.

Can I connect more than one device to the timer?

• Yes, as long as the maximum current (10 A, or about 2200W) is not exceeded. For continuous use, it is recommended that the load be up to 75% of the maximum permissible value.

The time interval does not correspond to the dial markings?

• Due to the wide range of time intervals, a relatively small turn of the knob can considerably change the duration of the time interval. For maximum accuracy, use a stopwatch to set the intervals.

The timer does not supply power?

• Check whether power is being supplied to the timer. If the timer does not work, contact your distributor.

Does the timer only work sometimes?

• Check the operating mode. Check whether light reaches the photocell (and vice versa).
