It is a clock with ate an thermometer with Type 7 segment outputs. Especially suitable for isplays: CD-23, CD-24, CD-53 an CD-54.
Select a functioning solely as a clock or combination with the ate an / or temperature, with a justable flash.
Supports be configure to isplay temperature in Celsius or ahrenheit.

POWER : 12VDC power supply we recommen Cebek ref. FE-123, which a apts to the nee s of the circuit. A positive an negative
input clamp.
Install a fuse an a switch for the protection an safety, as reflecte CE stan ar s.
Battery input : The mo ule has an input for 12 VDC battery. In case of loss of power supply, the circuit will switch to this entry
consumption, ensuring the maintenance an monitoring of operations of the circuit.
While the mo ule will serve as input battery to minimize the consumption, turn off the isplays, using only the minimum functions to
continue operations mo ule. Once power is restore , the isplays light up again without losing the continuity of operation.
The input circuit has no battery charging, so you shoul perio ically check the status of it.
At installation, connect the positive an negative battery to the correspon ing input of the mo ule. Observe the polarity in icate .
Connection page PROBE : The cable length between the probe an the basic circuit is ecisive for optimum accuracy. The maximum
istance that the mo ule supports, is 100 cm. For this connection I use shiel e cable, using the mesh connecting the terminal with
the groun symbol. For istances less than 40 cm. You can use stan ar cable.
Do not change, alter or a just the variable resistor circuit in icate as "Sensor A just", otherwise estabilize the factory settings an
therefore cause the temperature error.
PUSH INSTALLATION : Install two buttons at the entrances: ENTER an SELECT. The istance of the cable shoul not excee 50 cm.
UNCTIONS. SETTING TIME AND TEMPERATURE CORRECTION : To start time setting, press an hol Press the "Enter" an then
turn the power circuit. After 3 sec. the two isplays of the minutes start blinking an you can release the button "Enter".
The two isplays that remain unblinking, (h), are those that may change. Per-click Enter, it will increase by one. If you keep Enter
presse briefly, the increase will occur progressively faster.
To finish setting the time an start the minutes, briefly press the "Select", the correspon ing isplays the minutes be fixe an you can
mo ify the same way as on the hour. Complete setting the hour an minute, a new press on Select will isplay temperature correction
appear.
Accor ing to the ifferent con itions where the CD-26 gets installe an while the mo ule is factory set, a small margin of error may
occur between the actual temperature an collecte by the isplay. To correct this error, you can increase or ecrease to 5 egrees
base circuit temperature.
After setting the minutes, as we specifie above, when press Select only illuminate the isplay units, in icating that the isplay has
entere temperature correction. I factory is set to zero. Each press of Enter, will increase by one egree. From 5, each press will
ecrease a egree to get back to zero.
Finally a last-click Select recor the changes in the circuit an return the mo ule to normal isplay ata.

OPERATION. SAMPLING O TEMPERATURE: The mo ule has been esigne especially to isplay ambient temperatures, in
which the changes occur at a low spee . For this reason the circuit will wait for the temperature probe is stable for a short time to
isplay on the isplay, making it unsuitable for in ustrial controls, or places with fast.
BEHAVIOR O LEDS. The mo ule has several LEDs to in icate its operating status. The Scale LED will illuminate whenever you
select a time greater than 4 sec flashing. The Time an Temp LEDs alternately light when the isplay shows the time or temperature
