Cooling with 3-Stage Reheat and Night Setback/Setup

This conguration is the same as on the previous

page except for the addition of an SPST relay or

switch.

See Cooling with 3-Stage Reheat on page

24.

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.
