4. Use of the ALARM function
The multifunctional clock is equipped with an
alarm with buzzer and relay contact output.
When time alarm is selected, the buzzer will
sound and the relay will be activated, until a key
is pressed. The temperature alarm function will
only activate the relay output. (Relay : N.O.
1A/24V max. see drawing). A red LED in the up-
per right hand corner of the display will indicate
its operation. This allows you to hook-up an ex-
ternal device, or a relay which can handle bigger
voltages/currents.
Attention : When the countdown function is used, the relay will also be activated,
when the target date is reached, until a key is pressed. Therefore, take care when
using both functions.
5. Troubleshooting
The remote control operation indicator flashes when a button is pressed, but the clock
does not respond.
Check the battery of the remote control. If doubt, replace.
Check and see if the receiving indicator, located in the lower right hand corner of the
display, lights when a button is pressed. Interference from other transmitters operating
on the same frequency or influences from electrical fields or metals can disturb trans-
mitter/receiver performance or limit operating range. If necessary, move the unit to a
less affected location.
The unit suddenly stops operating, apparantly for no reason.
When the temperature sensor measures a too low temperature, it shuts down the unit.
Move the unit to a warmer location.
