SCPTnvType nvoRSVal
{SNVT_nv_type}
{}
{SNVT_temp}
Indicates nvoRSVal type.
For use with LonMaker and other tools.
SCPTminDel-
taTemp
nvoRSVal
{SNVT_temp_p}
{1.0...327.66}
{5.00}
Minimum deviation required to send out the network vari-
able.
SCPToffset[0] nvoRSVal Same as nvoRSVal Reference temperature point to adjust the offset
SCPToffset[1] nvoRSVal Same as nvoRSVal
Temperature value to output when the reference tempera-
ture set at SCPToffset[0] is input.
Offset = SCPToffset[1] – SCPToffset[0]
SCPTdefScale nvoRSVal
{SNVT_lev_percent}
{80.000...120.000}
{0.0}
Gain applied to SCPToffset[0]
SCPTsetpoint[0] nvoRSVal Same as nvoRSVal
nvoRSVal lower range temperature
SCPTsetpoint[0] < SCPTsetpoint[1]
SCPTsetpoint[1] nvoRSVal Same as nvoRSVal
nvoRSVal upper range temperature
SCPTsetpoint[0] < SCPTsetpoint[1]
SCPToffset nvoRSPVal
{SNVT_lev_percent}
{-163.840...163.835}
{0.0} nvoRSPVal zero (offset) adjustment.
Added to the calculation result with SCPTsetpoint[0,1] and
SCPTgain.
SCPTgain nvoRSPVal
{SNVT_muldiv
(mulplier,divisor)}
{0...32000,10000}
{10000,10000}
nvoRSPVal span (gain) adjustment.
Gain = Multiplier / 10000 (Divisor is fixed at 10000.)
Applied to SCPTsetpoint[0,1].

• nvoRSVal Offset Adjustment Example • nvoRSVal Gain Adjustment Example
nvoRSVal outputs 26°C
with the input 25°C.
SCPToffset [0] = 25.0
SCPToffset [1] = 26.0
nvoRSVal outputs 25°C with the input 25°C.
nvoRSVal outputs 36°C instead of 35°C
with the input 35°C.
SCPToffset [0] = 25.0
SCPToffset [1] = 25.0
SCPTdefScale = 110.0%
(36 – 25) / (35 – 25) = 1.1 = 110%
