High/Low Selector Relay
If all 6 inputs are not used, and if the low (L) output is used,
connect the last used input to the remaining unused inputs.
This keeps the low (L) output from reading "zero".
If only the high (H) output is used, it is not necessary to
connect the unused inputs.
If either output (L or H) must operate valve or damper
actuators, use an R532-L volume-booster relay to
increase air capacity for that output on a 1:1 basis.
