Remote Sensing

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.

•Room Temperature Control

Performed via a sensing network using the following sensors:

–Wall Sensors: TR21-A (10K) for averaging only, TR21 (20K), C7189U1005 (10K)

–Flush Mount Sensors: C7772A1012 (20K)

–Button Sensors: C7041P (20K)

•Duct Return Temperature Control Performed using the following 20K sensors:

C7041B/C7041C/C7770A/C7041J

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™)
