Cooling With 3-Stage Reheat And Night Setback/Setup - KMC Controls CTE-5202 Application Manual

Cooling with 3-Stage Reheat and Night Setback/Setup

This configuration 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 offset selected in ADVANCE > SETBACK
menu. See Change Configuration on page 6
Unoccupied/Standby Setback on page
NOTE: The night/unoccupied setback offset does
not apply to morning warm-up.
