SpaceTemp is the space temperature sensed by another node and is

(SNVT_temp_p)

14 to 122

typically bound to SpaceTemp of another node having a space temperature

Degrees C

sensor. If SpaceTemp has a value other than SI_INVALID it is used as the

(-10 to 50)

sensed space temperature by the node rather than using any local hard-

wired sensor. If the value is outside the allowed range of -10 to 50 degrees

C (-18 to 90 degrees F), then the node uses the value of the nearest range

limit. When SpaceTemp is not bound to another node, SpaceTemp may be

used to fix the sensed temperature. A management node may write a value

other than SI_INVALID, causing the node to use SpaceTemp instead of the

hard-wired sensor. An application restart or power failure causes the fixed

sensor value to be forgotten and SpaceTemp to be returned to

SI_INVALID.

SpaceTemp is the sensed space temperature from the locally wired sensor.

SpaceTemp is typically bound to SpaceTemp of another node which may

not have its own space temperature sensor but control the same space.

(-10 to 50)

The reported space temperature includes the offset correction

Config.SpaceTempZeroCal. If the space temperature sensor is not

connected or is shorted, or if SpaceTemp is bound to another node, then

SpaceTemp is set to SI_INVALID.

OdTemp allows one outside air temperature sensor at a node to be shared

(SNVT_temp_p)

-40 to 122

by many other nodes. When OdTemp is not SI_INVALID, then any local

Degrees C

sensor is ignored by the local control algorithm and OdTemp is used

(-40 to 50)

instead. If the value is outside the allowed range of -40 to 50 degrees C (-

72 to 90 degrees F), then the node uses the value of the nearest range

limit.

OdTemp allows the local outdoor temperature sensor to be shared with

other nodes and is typically bound to OdTemp on other nodes. If the local

sensor is configured by Select, OdTemp is periodically sent on the network.

If the local sensor is not configured or currently showing an error, the value

is SI_INVALID.

OdHum allows one outdoor humidity sensor at a node to be shared by

sensor, is ignored by the local control algorithm and OdHum is used

instead. If the value is outside the allowed range (10 to 90 percent), then

the node uses the value of the nearest range limit.
