YES
This configuration variable specifies whether the setpoint used is from
the knob on the wall module connected to the controller or from the
network via nciTempSetPts. If set to NO, all setpoints to be used come
from the network via nciTempSetPts. If set to YES, an additional option
set_pnt_knob must be set to specify type of setpoint adjustment (see
below).
OFFSET
This configuration variable specifies specifies the usage of the setpoint
knob on the wall module for the occupied setpoint. OFFSET specifies a
relative scale on the wall module where the setpoint is calculated by
adding the setpoint potentiometer value (± 5 K) to the appropriate
value of nciTempSetPts. ABSOLUTE_MIDDLE specifies an absolute
scale on the wall module. The setpoint knob directly determines the
center point of occupied cooling and heating setpoints. The respective
cooling and heating setpoint is determined by the setpoint knob
position adding or subtracting half of the user selectable ZEB defined
in nciSetPnts.<occ_mode>_cool or nciSetPnts.<occ_mode>_heat .
This applies to <occ_mode> OCCUPIED and STANDBY.
BYPASS_UNOCCUPIE
This configuration variable specifies the behavior of the override
D
button. BYPASS_UNOCCUPIED allows overriding the current
occupancy mode to OCCUPIED for a configurable bypass time, or
causing a permanent override to UNOCCUPIED. BYPASS allows only
the temporary override to OCCUPIED and canceling it.
LAST_WINS
This configuration variable specifies the priority of the local (wall
module push-button) or central (network interface) override. If
NETWORK_WINS is set and the network sends value NUL, then the
override button is active.
LED_OVERRIDE
This configuration variable specifies the display of occupancy and/or
override. LED_OVERRIDE shows the override from the bypass button
or from the network. LED_OCCUPANCY shows the effective
occupancy mode. LCD_DISPLAY is only used for T7560 Wall Modules.
The display shows the occupancy mode with different symbols, and the
override mode with flashing symbols.
