2-channel timer. 1+1 normally open contact, potential-free 16A/250V AC. With astro function. Standby loss only 0.03-0.4 watts. From production week 26/19 with display lighting. Modular device for mounting on DIN-EN 60715 TH35 mounting rail. 1 division unit = 18mm wide, 58mm deep. With the patented Eltako Duplex technology (DX), the normally potential-free contacts can still switch at zero crossing when switching 230V AC 50Hz, thereby drastically reducing wear. To do this, simply connect the N conductor to terminal (N) and L to 1(L) and/or 3(L). This results in an additional standby loss of only 0.1 watts. By using bistable relays, there is no coil power loss and no heating as a result, even when switched on. Up to 60 timer memory locations are freely distributed across the channels. With date and automatic summer/winter time changeover. Power reserve without battery approx. 7 days. Each memory location can be assigned either the astro function (automatic switching after sunrise or sunset), the switch-on and switch-off time or an impulse switching time (which triggers a 2-second pulse). The astro switch-on or switch-off time can be shifted by plus or minus 2 hours. In addition, a time shift of up to plus or minus 2 hours influenced by the solstices can be entered. With control input (+A1) for central control ON or OFF with priority. Supply voltage and control voltage for the central control 8..230V UC. The timer is set using the MODE and SET buttons and a button lock is possible. Pressing MODE or SET switches on the display lighting. 20 seconds after the last MODE or SET button was pressed, the program automatically returns to the normal display and the display lighting is switched off. Setting the language: Each time the supply voltage is applied, the language can be selected within 10 seconds using SET and confirmed with MODE. D = German, GB = English, F = French, IT = Italian and ES = Spanish. The normal display then appears: day of the week, time, day and month. Fast forward: For the following settings, the numbers increase quickly if the Enter key is pressed and held down. Releasing and pressing again for a longer time changes the direction. Setting the time: Press MODE and then, under PRG (program), use SET to find the CLOCK function and select it with MODE. Under S, use SET to select the hour and press MODE to confirm. Repeat for M for minute. Setting the date: Press MODE and then, under PRG, use SET to find the DAT function and select it with MODE. Under J, use SET to select the year and press MODE to confirm. Repeat for M for month and T for day. MO (day of the week) flashes as the last setting in the sequence. This can be set with SET and confirmed with MODE.Set location (if the astro function is required): You will find a list of German cities at the end of the operating instructions. Press MODE and then use SET to search for the POS function at PRG and select it with MODE. For BRT, use SET to select the latitude and confirm with MODE. Likewise, use MODE to select the longitude at LAE and press MODE. Now use SET to select the time zone at GMT and press MODE to confirm. If required, a time difference of up to plus or minus 2 hours can now be entered for both channels at WSW (winter solstice) and SSW (summer solstice). Manual switching ON or OFF with priority: Press MODE and then use SET to search for the INT function at PRG and select it with MODE. For KNL, use SET to select channel 1 or 2 and confirm with MODE. Now use SET to switch between AUT (automatic), ON or OFF. After confirming with MODE, the switching position of the selected channel changes if necessary. If the switching state is to change automatically again when a time program is activated,
