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

**Equivalent to NEMA 1/4 horsepower rating for a hermetically-sealed motor. Allowable load must be determined from fan nameplate ratings .
†North American national electrical codes require all ungrounded conductors to electric resistance heating to be broken at the thermostat OFF setting. The 208V and 230V resistive ratings are not UL approved. The 230V rating is site-approveable in Canada on 416V 4-wire Wye distributed systems. The non-inductive rating for 230V “a.c. mains” with one ungrounded conductor is 6.0A.
