Occupied 
Cool & Heat 
Setpoints 

network Input 
SNVT_temp_p 

nviSetpoint 

 

This input network variable is used to allow the occupied 
temperature setpoints only to be changed via the network from a 
single analog value. (Note: the Unoccupied setpoints are not 
changed). The corresponding heating and cooling values are 
derived from the minimum deadband configuration value 

 

Default Null Value: 621.81°F (327.67°C or 0x7FFF) 

 

Ex. If the minimum deadband configuration value = 2 °F and 
nviSetpoint = 70°F. 

• 

The resulting Occupied heating setpoint will equal 69 °F which is 

derived from 70 °F minus ½ the minimum deadband configuration 
value of 2 °F 

The resulting Occupied cooling setpoint will equal 71 °F which is 
derived from 70 °F plus ½ the minimum deadband configuration 
value of 2 °F 

 

This input network variable is used to set the time and date of the 
Space Comfort Controller.
