            Frequently Asked Questions

            hide show

            what is the maximum amount of settings which can be achieved with the CCT15854?

            56 settings

            Video: CCT15854 Programming Schedules

            Are there instructions available for the CCT15854 timer?

            Please find attached instructions for the CCT15854 Din rail mount timer.


            Instructions for Merlin Gerin timer CCT15837 or CCT15854

            See the attached installation instructions for both timers.


            Is the battery inside the CCT15854 timer replaceable?

            No. Unfortunately, the battery can not be replaced as it is soldered on the PCB.

            What is the new code for the CCT15837 timer?

            The new code is CCT15838, but the CCT15838 only has a N/O contact not a C/O contact like the previous version.

            Why is there a voltage present at the terminals of the open contact of an IHP digital time clock.?

            The new generation programmable time switches (CCT15720, CCT15721, CCT15722, CTT15723, CCT15850, CCT15851,CCT15852, CCT15853, CCT16650 and CCT15652) integrate the O-crossing technique. This is an electronic procedure enabling the circuit to be opened at zero current, which enables the electromechanical contact to be operated off-load.

            This is used to avoid the inrush currents of certain loads, particularly lighting.

            This solution involves a low leakage current traveling through the electronics which generates residual voltage at the contact terminals, even when open. This can cause problems when very low loads (small relays, LEDs, etc.) are operated, as the receiver may be "held on" by this spurious voltage. 

            For this type of application (low load), a conventional electromechanical programmable time switch should be used.

            Is the CCT15837 still available for Purchase?

            No, the CCT15387 has been superceeded by the CCT15838. This only has 1 N/O contact.

            What is a CCT15284

            It is an IC2000 - twilight switch

            What is the replacement for CCT15837 ?

            The replacement is the CCT15838 Which has higher load ratings but is a N/O contact instead of a C/O
            (see attached file)

            Does the CCT15837 time clock have a backup battery

            Yes the CCT15837 does have a backup battery

            What is the replacement for the 4TCD / 4TCD1 ?

            4TCD is 7 day Clipsal timer  , made obsolete and has a Schneider Equivalent of  CCT15854.
            Please see attached data sheets on both the products for more details.
