3. Operating manual
3.1. Installation and putting into operation
The clock is installed depending on the type of installation. At the rear gripping,
you have to mount the console with four screws to desired position. Respect proper
console rotation. Slip-on the console as the clip at the rear side of the clock is
located from the outside and mount with applied screws M6. Mount in desired
elevation angle and finalize the screws.
Obr.2: Rear gripping
Obr.3: Terminals in gripping console
The side gripping is possible to a vertical column or a wall. Mounting to a column
is possible with steel (rostfest) mounting stripes. Use at least two stripes that are
placed to jags in upper and lower part of the console. To achieve higher stability,
you can use up to 5 stripes. Stripes are firmly finalized and fixed by clips. The

column diameter shouldn’t be smaller than 100mm because of placement of the
socket for cables.
Obr.4: Side gripping to a column
After mounting the clock, connect the power supply and put the temperature sensor
to an adequate place. With the internal version of clock, there’s a supplied power
supply SSZ02 with protection IP65 in the box. If you can put the power supply
close to the clock, connect the power supply cable directly through the terminal to
the output connectors (13.7V/1.5A). Remove the cover, put the power supply cable
to the terminal and connect the blue wire to the –jack and the red (brown) wire to
the + jack. Connect the network power supply 230V/50Hz to the main terminal.
Mount the power supply cover and finalize screws and both terminals. If you have
to place the power supply further from the clock, you can use the applied
installation box with terminal and jacks and extend the power supply cable to
proper length (max. 10m).
!!!Warning: the clock can be supplied by DC in range of 12÷30V. Supplying by
other DC can cause malfuction or even destroying of the clock. In no case, do
not connect the clock to AC 230V/50Hz.
For exact temperature measurement, the proper place of the sensor is very
important. Put the sensor into a proper position to avoid direct sunlight, wind and
objects that produce heat. It’s recommended to put the sensor into supplied white
plastic pipe and mount it with stripes.
!!!Warning: you must remember that the clock shows the temperature in place
of the temperature sensor. This temperature can be different from the place of
the clock.

!!! Warning: controlling of the double-sided clock is possible only from the front
side. If the clock is gripped at the side, you have to stay in front of the clock and
the console must be at the left side. The controller range is app. 20m. The solar
radiation reduces the operating range and you have to step closer. We
recommend to set up the clock at lower solar radiation.
