Configuration parameters
nciIVAVtime, nciItimeHeat
The parameters holds the integral time for the cooling and hea-
ting sequence gain. Default value 900 s (15 min).
nciSpaceTempOfst
The parameter is used for adjusting the temperature setpoint.
Default value 0.0 °C.
nciMinFlow, nciMaxFlow
The parameters are used for setting the minimum and maxi-
mum flow allowed. Default values 0 l/s and 65535 l/s.
nciMinFlowHeat, nciMinFlowStand
The parameters are used for setting the min. flow allowed at active
heating (only relevant for applications with electrical reheat but
without a fan) and standby respectively. Default value 0 l/s.
nciFlowOfstSlave
The parameter is used for adjusting the flow of the slave con-
troller (see section 5.3.8). Default value 0 l/s.
nciCO2PerVolt
The parameter is used for setting a conversion factor for the
signal from the carbon dioxide sensor to a concentration in
ppm. Default value 200 ppm/V.
nciSpaceCO2Low, nciSpaceCO2High
The parameters are used for setting the air quality control li-
mits (se section 5.3.3). Default value 400 and 1000 ppm.
nciHeatPrimMin (only TAC Xenta 102-VF)
The parameter is used for setting the smallest heating valve
opening allowed (se section 5.3.6). Default value 0%.
nciInstallType
The parameter is used only at free-standing operation and is set
to show that the node should define its own address (see section
8.5.3).
nciSndHrtBt
The parameter is used for determining how often the nvo’s,
which are transmitted continuously on the net, should be sent
(see section 8.3).
nciRcvHrtBt
The parameter is used for determining how long time max. the-
re may be between updating those nvi’s, for which the control-
ler expects continuous updating (see section 8.3).
