The specifications given in this publication do not
include normal manufacturing tolerances. Therefore,
this unit might not exactly match listed specifications.
This product is tested and calibrated under closely
controlled conditions; minor performance differences
can be expected if those conditions are changed.
Models: See Table 1.
Dimensions: See Fig. 1.
Finish (color): Trident White.
Batteries: No batteries required.
Table 1. T7350 Thermostat Features.
a
All models are down-selectable and can be configured to control fewer stages than the maximum allowed.
b
One extra stage (of either heat or cool) can be configured using the auxiliary relay.
c
Heat pump applications for these models have a maximum of two heat stages and two cool stages.
Mounting Means:
Mounts on subbase.
Subbase Mounts On:
Wall: Using two 5/8 in. long #6-32 screws (included).
Outlet Box: Using sheet metal screws.
Throttling Range for Modulating Outputs:
Automatically adjusts based on heat/cool stages. Manually
adjustable with TStatSpec software or PDA.
Clock Accuracy (at 77° F [25° C]): ±1 min./month (30 days).
Minimum Stage Operation Time (fixed):
Minimum On
Heat: 1 minutes.
Cool: 3 minutes.
Minimum Off (Cool and Heat Pump): 1 minute.
Electrical Ratings:
Power: 24 Vac, 50/60 Hz.; 20 to 30 Vac, 50/60 Hz.
Input:
Temperature: 20K ohms.
Humidity: 0-10 Vdc.
Outdoor: 3000 PTC.
Discharge Air: 20K ohms.
Occupancy Sensor: Dry contact switching 30 Vdc at 1 mA.
All Relay Outputs (at 30 Vac):

Default Settings: See Table 2.
Loss of Power: The thermostat maintains programmed times
and temperatures for the life of the product. Clock and day
information is retained for a minimum of 48 hours.
NOTE: To achieve the 48-hour power-loss clock retention,
the T7350 must be powered for at least 5 minutes.
Communicating Model T7350H:
Connection Terminals for the LonWorks Bus.
Network jack for quick access by personal computer based
tools.
Communications service-pin pushbutton to simplify startup.
