T775P with one T775S module: 8 relay
outputs (8 stages).
T775P with two T775S modules: 12 relay
outputs (12 stages).
NOTE: The last output is available to be used as the
pump output. For example, a T775P with one
expansion module provides 8 outputs, and
the last output (#8) is available for use as the
pump output. See “1.3.5. Setup Last Output”
If # of stages = 1, 2, or 3 then, pump = 4.
If # of stages = 4, 5, 6, or 7 then, pump = 8.
If # of stages = 8, 9, 10, or 11 then, pump =
12.
