7. Appendix A: Adding a Timer Stage
Adding a timer stage to the RBU-27 SE can save fuel costs. Rather than running fans continuously, adding a timer
ensures that they are used only when needed.
The following diagram illustrates a system consisting of a timer wired to the RBU-27 SE relays coils.
Figure 15: Backup Unit with an External Timer
The following diagram illustrates a system consisting of a timer and coolers wired to the RBU-27 SE relays coils. By wiring
the unit to a timer, the RBU-27 SE becomes a four level cooling controller:
o Cool 1 on timer for minimum ventilation during cold/baby bird conditions
o Cool 1 on full time
o Cool 1 and 2 on full time
o Cool 1, 2 and 3 on full time
