Honeywell T6051A1057 specifications Application, Installation, 95-6979-l

APPLICATION

The T4051, T6051, and T6052 are heavy duty. line

voltage thermostats used to control fan coils, fans, motor

starters, valves, contactors, and circulator motors in

heating and/or cooling systems.

The	T4051	A is	for	heating	only	control.	The	T4051	B
‘IS for	cooling	only	control.		The	T4051D	is for	electric
‘heat	applications		and	is	used	without	a	subbase.

The T6051A may be used in heating only systems,

cooling only ‘systems, combination heat-cool systems

,(changeover must be provided), or as a series 60 con-

troller for valves and motors.

: The T6052A is for two stage heating or two stage

jcooling systems. The T6052B is for one stage heating-

cooling systems with automatic changeover.

The 0651 Subbase may be used with the thermostats

bo provide system switching at the thermostat location.

iRefer to applicable specification sheet for additional mformation.

~Electrical ratings for the heavy duty thermostats are

given in Table 1.
