This conguration is the same as on the previous
page except for the addition of an SPST relay or
switch.
See Cooling and 3-Stage Reheat on page
35.
The switch or relay is driven by a night/unoccupied
setback/setup signal from other equipment not
shown. When the contact is closed (e.g., by a timer),
setback/setup mode initiates, changing the setpoint
by the oset selected in ADVANCE > SETBACK
menu. See Change Conguration on page 6 and
Unoccupied/Standby Setback on page 5.
NOTE: The night/unoccupied setback oset does
not apply to morning warm-up.
NOTE: This conguration requires the system fan
to be on during setback/setup mode.
NOTE: Triac outputs on the REE-5001 are for 24
VAC loads only. The phase side of the
transformer connects to the “common” side
of the load (contactors).
NOTE: See also the REE-5001 Installation Guide.
(See also the Cooling with 3-Stage Reheat and Night
Setback/Setup section with a CTE-5104 in the CSP-
5001/5002 Applications Guide.)
