T6380, T8380 SERIES
Electronic Fan Coil Thermostats
The Um and T8380 Series
of electronic Ian coil ihcrmoslals
provide precision ON-OFF control
of fan-forced heating, ventilating
and air conditioning equipment.
There are models for
cooling-only, heating-only, and
heating-cooling fan coil systems
with manual or remote heat-cool
changeover.
llydronic Ian coil systems may
be four- or two-pipe configuration
iitted with zone or VC Series valves.
f-an control options include
constant, cycled, or user selectable
“ON-.UTO” operation. Manual Ian
speed selection is standard. .Ml
models can turn the system off.
✓ Electronic tcmpcraiurc sensing provides energy-
elTiciem. precision operation for imixiinum comfort.
✓ Adjustment ranges 55® to 90®F or 13® lo 32®C.
✓ Optional scalcpiatc nxarked "Cool Warm" available.
✓ Easy-to-use set point knob.
✓ LED system status indicator.
✓ Contemporary white sculpted styling.
✓ Rugged molded iheniioplaslic housing with
captive mounting screws, mounts on single-gang
NEMA-siandard (U.S.) electrical box.
✓ Optional range stops and cover locking kit available.
✓ Vertical or horizontal mounting configurations.
✓ .Available for line or low-voltage control.
✓ Suitable for electric heat and inductive loads such as
valves, relays, contactors, compressors, and fans.
^ Screw terminal block wiring.
^ Three level fan speed selection.
^ System OFF disconnects all connected loads.
