Honeywell T6380 Electronic Thermostats
APPLICATION
The T6380 series of electronic fan coil thermostats provide precision line voltage control of fan-forced Heating, Ventilating and Air Conditioning equipment. Models are available for the cooling-only, manual heat-cool changeover, or remote heat cool changeover systems. Hydronic source heat-cool systems may be two or four-pipe configurations with 0, 1, or 2 valves. Fan control options include constant, cycled, or user selectable “On-Auto” operations. Manual fan speed selection is standard. All models feature an “Off” switch.

INSTALLATION
MOUNTING
- Mount the thermostat on an inside wall 4’ to 5′ [1.5 m] above the floor. Do not mount where thermostat can be affected by drafts, radiant heat from the sun, or other sources of heat.
- T6380’s mount on NEMA standard 2″x3″ single gang flush or 2″x4″ surface mount electrical box, or on 4″x4″ box with mud ring adaptor (not provided).
WIRING
Internal schematic and external wiring connections are shown in Fig. 2a through Fig. 8c. Wiring connections may be made to the 8 position screw terminal block with 1- 14 AWG, or 2- 18 AWG, solid or stranded copper wires
OPERATION
As the temperature changes, the thermostat makes to open a valve and/or power a blower to provide heating or cooling. The speed at which the air is circulated is controlled by the FAN switch. Continuous (ON) or intermittent (AUTO) fan operation is determined by model number
CHECK-OUT
- Turn power on. Check out operation according to the SYSTEM switch present.
- SYSTEM switch OFF de-energizes valve and fan circuits
Models T6381B,: T6383B
- SYSTEM: HEAT – OFF – COOL Set the SYSTEM switch to HEAT. Rotate the thermostat knob clockwise to energize the heating valve and/or fan (fan auto/cycled mode).
- The system LED on the thermostat will light when the heating circuit is energized Set the SYSTEM switch to COOL. Rotate the thermo stat knob counter-clockwise to energize the cooling valve and/or fan (fan auto/cycled mode). The system LED on the thermostat will light
Model T6387A
- SYSTEM: ON -AUTO – OFF
- Set the SYSTEM switch to ON. The valve will operate on heating or cooling cycle depending on whether hot or chilled water is being supplied. The fan will run continuously.
- Set the SYSTEM to AUTO. The fan will cycle with the heating or cooling operation
Models: T6381A; T6383A
- SYSTEM: HI-OFF-MED-LO
- Set the SYSTEM switch to HI. Rotate the thermostat knob clockwise to energize the heating\cooling valve and/or fan ( constant or cycled fan). The system LED on the thermostat will light when the heating or cooling circuit is energized.
SETTING:
- The T6380 temperature scale is marked 55 to 90°F or 13 to 32°C, depending on the model. Set the dial indicator marker to the desired temperature.
CALIBRATION:
- T6380 thermostats are accurately calibrated at the factory under controlled conditions. Do not attempt to field calibrate this device.This thermostat has line voltage connections.
