CanbeconfiguredusingHoneywell’slineof10Kohmand
20Kohmcommercialsensors,supportingthefollowing
applicationsthatresidentialthermostatsdon’t:
• TemperatureAveragingNetworks
Because commercial thermostats can be configured
toa20Kohmnetwork,temperatureaveragenetworks
of anywhere from 1 to 9+ sensors can be deployed.
Combinationsof10Kohmand20Kohmsensorsare
use to create the averaging network. The most popular
sensorsaretheTR21andTR21-A(averaging)10Ksensor
andtheTR21andTR21-A20Ksensor.

Unit Vent

• CanbeprogrammedtocontrolASHRAECycle1unitvent
applications.
• Unitventoutside-airdampercanbeprogrammedthrough
theEconomizerfeature.Whentheunitventisonand
occupied, the thermostat will enable the economizer
relay to keep the outside air damper at the maximum
percentage opening. Only maximum percentage
opening is available; the thermostat will not modulate
the damper. When the unit vent is unoccupied, the
thermostat will close the damper.
• RangeStopfeaturecanbeconfiguredtoprogramalow
limit setpoint to prevent equipment damage from freezing.

Commercial Codes

• Complywithcommercialbuildingcodesandmeetthemost
rigorousstandard,California’sTitle24.
• Noholdbuttonisavailable,sothethermostatremains
in permanent schedule.
• Overridebuttonallowsthetenanttooverridean
unoccupied mode for up to 4 hours and can be configured
foranexactoverridesetpoint.Dependingonthepartial
lockout level deployed, a user may override to an exact
setpoint or be given a setpoint range to choose from.
• Pre-OccupancyPurgeandEconomizerfunctionsallow
the building owner to meet all HVAC ventilation codes for
commercial buildings.

Lighting Load Reduction (TOD)

• Commercialbuildingsarefrequentlyautomatedtoturnoff
lighting loads. Lighting loads can use even more energy
than HVAC systems in commercial buildings, and 79%
of commercial buildings have off-hours lighting load
reductioncontrol.Byusingthetime-of-dayrelay(TOD)
in conjunction with a lighting control system, users can
automatetheirlightingloads.(NotavailableonMultiPRO™)
