nviSetPtOffset

SNVT_temp_p
-18 to 18 DDF (-10 to 10 K)
589.806 DDF (327.67 K) =
INVALID

0 (if bound but fails to be
received or at application
restart)

This input variable is used for binding third party nodes to
authorize them for setpoint shifting. nviSetPtOffset is stored in
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.

nviSpaceTemp

SNVT_temp_p
0 to 104°F (0 to 40°C)
621.806°F (327.67°C) =
INVALID

INVALID

(if bound but fails to be
received or at application
restart)

This input variable is the space temperature transmitted from
another Excel 10 controller or another node that has a tem-
perature sensor wired to it. If bound or has a value other than
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.

nviTest output1_cmd

BYTE
NORMAL_HC_MODE
OFF1_OFF2
ON1_OFF2
OFF1_ON2
ON1_ON2
TESTPOSITION


0
1
2
3
4
5

NORMAL_HC_MODE
(at application restart)

This input variable is used by factory test, OEM field test, field
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.

nviTest output1_test_pos

SNVT_lev_percent
0 to 100%

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.

nviTest output2_cmd

BYTE
NORMAL_HC_MODE
OFF1_OFF2
ON1_OFF2
OFF1_ON2
ON1_ON2
TESTPOSITION


0
1
2
3

5

NORMAL_HC_MODE
(at application restart)

Same as output1_cmd for output 2.





nviTest output2_test_pos

SNVT_lev_percent
0 to 100%

0 (at application restart)

Same as output1_test_pos for output 2

nviTest reheat_cmd

BYTE
NORMAL_HC_MODE
OFF1_OFF2
ON1_ON2


0
1
4

NORMAL_HC_MODE
(at application restart)

This input variable is used to test the reheat relay.
