Omron H5CR Timer Replacement Kit Instructions
CFSA Wiring Instructions
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. Remove the jumper wire labeled 51 on Cool Timer terminal 1 to Dry Timer terminal 4. Discard the
wire. (Leave the other 51 wire on Dry Timer terminal 4 alone.)
3. Add a wire labeled 51 to Dry Timer terminal 4 to the DTR relay terminal 13.
4. Locate the wire labeled 29 on Dry Timer terminal 6 and Unload Timer terminal 3. Remove the wire
from the Unload Timer terminal 3 and place it on UTR terminal 9.
5. Remove both wires labeled 55 on the Unload Timer terminal 1 and relocate both of the wires to the
CTR relay terminal 13.
6. Remove the jumper on the Cool Timer located between terminals 6 and 8. Discard this jumper.
7. Remove the jumper on the Unload Timer located between terminals 6 and 8. Discard this wire.
8. Locate the wire labeled 40 between Cool Timer terminal 7 and Unload switch. Move the wire from
the Cool Timer terminal 7 to UTR terminal 6. Leave the other end connected to the Unload switch.
9. Remove the wire labeled 40 between Dry Timer terminal 7 and Cool Timer terminal 7. Discard
this wire.
10. Remove the wire labeled 40 between Unload Timer terminal 4 and Dry Timer terminal 7. Discard
this wire.
11. Remove one of the wires labeled 38 (does not matter which one as long as it will reach) on the
Dry Timer terminal 1 and re-attach it the Unload Timer terminal 1.
12. Add a jumper labeled 38 from the Dry Timer terminal 1 to the Cool Timer terminal 1.
13. Add a jumper labeled 38 from the Cool Timer terminal 1 to the Unload Timer terminal 3.
14. Add a jumper labeled 38 from the Unload Timer terminal 3 to Unload Timer terminal 1.
15. Add a wire labeled 94 between Cool Timer terminal 6 and DTR terminal 9.
16. Add a wire labeled 94 between DTR terminal 9 and UTR terminal 12.
17. Add a wire labeled 95 between Cool Timer terminal 8 and DTR terminal 5.
18. Add a wire labeled 96 between Unload Timer terminal 6 and CTR terminal 9.
19. Add a wire labeled 96 between CTR terminal 9 and UTR terminal 10.
20. Add a wire labeled 97 between Unload Timer terminal 8 and CTR terminal 5.
21. Add a wire labeled 98 between UTR terminal 5 and Dry Timer terminal 7
22. Add a wire labeled 48 between UTR terminal 8 and Cool Timer terminal 7.
23. Add a wire labeled 100 between UTR terminal 13 and Unload Timer terminal 4.
24. Connect a white wire (neutral) to terminal #2 on the terminal strip or any AC neutral connection point
(white wire with label 2) and connect the other end of it to UTR terminal 14.
25. Add a wire labeled 2 between UTR terminal 14 and CTR terminal 14.
26. Add a wire labeled 2 between CTR terminal 14 and DTR terminal 14.
