Set points should be kept near the values that appear on the unit nameplate.
Each unit is carefully sized to match the expected load, as specified in the original order.
Attempting to operate a unit far from rated conditions can have unexpected results, such
as excessive evaporation, condensation in unexpected locations, and other problems. If
set points must be changed, air-temperature set point and water-temperature set point
must be changed together.
NOTE: Unless the unit submittal data specifies special operating conditions, do not
attempt
to operate the unit at a space temperature below 78°F (25.6°C).
{
NOTE: In the image above and the discussion
at right, “bbb”, “ddd”, “eee”, and “ggg”
are placeholders.
Your screen will show the set points
for your unit.
NOTE: The test “Pool 2 Set . . . gggF” is
optional and may not appear on all units.
NOTICE

attempt to operate the unit at a space temperature below 78°F (25.6°C). See
further instructions below.
Risk of uncontrolled evaporation.
Improper changes to air and water temperatures can profoundly affect the
