Omron H5CR Timer Replacement Kit Instructions
CFAB 150-320 Wiring Instructions
NOTE: These wiring instructions are only good for models built after 4/99 and shown in Figure 2 on Page 4
and Figure 3 on Page 5 . If you have the older version, you will need to refer to the wiring schematic
labeled pre-99 in Figure 5 on Page 10 and Figure 6 on Page 11 .
1. Install each new timer one at a time. Make note of what wire numbers are on each terminal of the old
H5CR timers. Then when you install the new H5CX timers, replace the wires back onto the same
numbered terminal they were on with the old timers. We will move these later but it is important that
we know where they are so there is less confusion on the rewiring of this circuit. (NOTE: There is no
terminal 10 on the new H5CX timers, so the jumper between 8 and 10 on all timers can be safely
removed and discarded.)
2. Locate the wire labeled 35 between Unload Timer terminal 1 and Cool Timer terminal 4. Disconnect
the wire from the Unload Timer terminal 1 and move it to the CTR relay terminal 13. (NOTE: If the
wire is not long enough, replace it with a longer wire.)
3. Remove the wire labeled 80 on Dry Timer terminal 6 and Unload Timer terminal 3. Discard the wire.
4. Locate the wire labeled 80 on the Unload Timer terminal 3 to the Reset switch and relocate the wire
from Unload Timer terminal 3 to the Unload Timer terminal 1. Re-label both ends of this wire as
wire 32.
5. Add a jumper between Unload Timer terminal 1 and Unload Timer terminal 3. Label this wire as
wire 32.
6. Locate the remaining jumper wire labeled 80 on the Dry Timer between terminals 6 and 8, remove
the wire label 80 sticker on this jumper and discard. Leave the jumper between 6 and 8 on the
Dry Timer.
7. Remove the jumper labeled 81 on the Cool Timer located between terminals 6 and 8. Discard
this jumper.
8. Remove the jumper labeled 82 on the Unload Timer located between terminals 6 and 8. Discard
this jumper.
9. Remove the wire labeled 83 between Dry Timer terminal 7 and Cool Timer terminal 7. Discard
this wire.
10. Remove the wire labeled 83 between Cool Timer terminal 7 and Unload Timer terminal 7.
Discard this wire.
11. Locate the wire labeled 83 between Unload Timer terminal 7 and Unload Timer terminal 4.
Discard this wire. Leave the other 83 wire on the Unload Timer terminal 4.
12. Locate the wire labeled 33 on the Cool Timer terminal 1 and attach it to terminal 13 of the DTR relay.
(If the wire is not long enough, replace the wire with a longer piece between DTR terminal 13 and
5CR terminal 8.)
13. Add a wire labeled 83 from Unload Timer terminal 4 to UTR terminal 13.
14. Add a wire labeled 32 between Dry Timer terminal 3 and Cool Timer terminal 1. (NOTE: This will
place three (3) wires labeled 32 on terminal 3 of the Dryer Timer.)
15. Add a wire labeled 32 between Cool Timer terminal 1 and Unload Timer terminal 3.
16. Add a wire labeled 85 between Cool Timer terminal 8 and DTR terminal 5.
