Description
Zone setpoint temperature
Upper temperature bound on deviation from configuration
parameters setpoint during Occupied Mode
Lower temperature bound on deviation from parameter setpoint
during Occupied Mode
Defines upper temperature limit in Unoccupied Mode;
HVAC equipment remains off while the zone temperature is
between the upper and lower limits
Defines lower temperature limit in Unoccupied Mode;
HVAC equipment remains off while zone temperature is
between the upper and lower limits
Room thermostat override duration (240 minute maximum
duration); after time limit expires, room thermostat goes into
regularly scheduled mode
Comfort Zone upper delta during Override Mode
Comfort Zone lower delta during override Mode
CH: To change the radio channel number; default = 11
GI: To change the device network group ID; default = 111.111
DI: To change the unique thermostat device ID; default = 71.40
1: Occupied
2: Unoccupied
Temperature range around setpoint, to prevent HVAC from
chattering
Maximum temperature allowed in zone; fail-safe feature
applicable to all zones
Minimum temperature allowed in zone; fail-safe feature
applicable to all zones
