0 (if bound but fails to be
This input variable is used for binding third party nodes to
received or at application
authorize them for setpoint shifting. nviSetPtOffset is stored in
restart)
RAM and will be initialized to zero after application restart or
power failure. If nviSetPtOffset is bound and fails to be received
periodically as configured with nciRcvHrtBt, it will be reset to zero.
INVALID
This input variable is the space temperature transmitted from
(if bound but fails to be
another Excel 10 controller or another node that has a tem-
received or at application
perature sensor wired to it. If bound or has a value other than
restart)
INVALID, then it is used as the sensed space temperature instead
of the wired wall module's temperature. nviSpaceTemp may be
set to a value other than INVALID using a LNS tool when
nviSpaceTemp is not bound to set the temperature to a fixed
value.
NORMAL_HC_MODE
This input variable is used by factory test, OEM field test, field
(at application restart)
installation, and field testing to manually command the physical
output 1 when the node has been put into manual mode
(nviManualMode = MODE_MANUAL).
NORMAL_HC_MODE: output 1 remains in its current position
OFF1_OFF2, ON1_OFF2, OFF1_ON2, ON1_ON2: set the
individual triacs ON or OFF
TESTPOSITION: sets output based upon output1_test_pos.
0 (at application restart)
This input variable is used for the TESTPOSITION of the
output1_cmd and is based upon the configured runtime/cycle
time.
NORMAL_HC_MODE
Same as output1_cmd for output 2.
(at application restart)
0 (at application restart)
Same as output1_test_pos for output 2
NORMAL_HC_MODE
This input variable is used to test the reheat relay.
(at application restart)
