White Rodgers T7351F Office Building Zones, Heat Pumps, Equipment Protection, Web-Based Interface

Office Building Zones

•The T7350 is one of the only Honeywell thermostats that integrate with occupancy sensors for office zones that are normally unoccupied or partially occupied.

(T7350D, M, H and T7351F)

•T7350 Wall Modules, including the T7771, TR22, TR23 and TR24 models allow for setpoint-only adjustment with range stops, temporary override control or a combination of both to provide the end-users with flexibility to provide optimal comfort during occupied events. (T7350B, D,

M, H and T7351F)

•Customizable Recovery Ramp feature guarantees the exact temperature specified when the office opens.

(All Models)

Heat Pumps

•Outdoor Air Sensor automatically turns off heat pump equipment in cold climates. The T7350 is the only Honeywell thermostat that uses both an outdoor air sensor and indoor sensors/wall modules for heat pump control applications. (T7350B, D, H and T7351F)

Equipment Protection

•Discharge Air Sensor detects abnormally high or low dis- charge air temperatures and shuts down equipment

if limits are exceeded. (T7350B, D, M, H and T7351F)

Modulating Control —

Discharge Air Control

•By tuning the PID loop, optimal control can be achieved. 20K ohm duct sensors can be used in the wall module ter- minals for temperature sensing. The modulating output will control the damper position. (T7350M, H)

Modulating Control – Hydronic Boilers and Pumps

•Combine modulating control and on/off relay control.

The modulating output can control modulating actuator valves during the heating season and up to 2-stage conventional cooling during the cooling season. (T7350M, H)

•Ideal for split systems that have separate heating and cooling equipment and need both a modulating output and a conventional output. The fan relay can be config- ured for either conventional (plenum switch controls fan) or electric (thermostat energized fan on call for heat) applications. (T7350M, H)

•Various hydronic control applications are possible, including unit ventilators, fan coils or any other modulat- ing system. The modulating outputs support both direct and reverse acting signals. (T7350M, H)

Communicating Control

•Using the Honeywell Command Display S7760A, the

Honeywell LonStation™ front-end or the Honeywell XL15B Web Building Manager, a single user interface can be accessed to perform the following functions: (T7350H)

–Group Scheduling

–Group Override/Setback

–Trending (not supported with command display)

–Alarming (not supported with command display)

–Demand Limit Control (XL15B only)

–LonSpec™ Configuration PC Tool

–Web-Based Control (XL15B only)

–Dial-Up Control (LonStation only)

Web-Based Interface

•Using Honeywell’s WebStat® Controller in conjunction with the T7350H communicating thermostats allows for a single user interface to be used during system setup, commissioning, monitoring and troubleshooting. With the WebStat Controller, the following functions are enabled:

–Group Scheduling

–Group Override-Setback

–Trending

–Alarming

–Custom Graphics and Floorplans
