The T-4000 Series Pneumatic
Room Thermostats provide
individual space temperature
control in all types of heating and
cooling applications. By producing
a proportional output signal, these
thermostats modulate controlled
devices in response to load
changes in the space. This
imposes the least demand on
mechanical heating and cooling
apparatus. A variety of high
volume output and low volume
output controllers are available to
meet the functional requirements of
any control system. Auxiliary
devices are available to perform
functions such as two-position
action, high-low pressure selection,
sequencing, etc.

All models feature an output test
connection which can be used for
service and calibration.

The T-4002 is a single temperature
thermostat available in direct and
reverse acting models.
The T-4003 submaster thermostat
can be reset from a remote location
or in accordance with a reference
temperature variation. An increase in
master pressure from a remote
source will increase (direct
readjustment) or decrease (reverse
readjustment) the set point of the
direct or reverse acting model
The T-4054 energy manager
heating-cooling room thermostat
features an adjustable deadband of
0 to 30F° (0 to 16C°) between
heating and cooling set points This deadband encourages
energy conservation and prevents
energy waste by eliminating
heating and cooling overlap.
The T-4506 is a dual temperature,
dual dial thermostat designed to
provide individual day and night
or two set point temperature
control. The set point change is
accomplished with a change in
supply pressure. A 15 PSIG
105 kPa) supply represents the
lower element and a 20 PSIG
(140 kPa) supply represents the
upper element. The action of
both elements is the same. A
change in either set point does
not affect the other set point. On
day-night applications with
20 PSIG representing the night
set point, an optional manual
indexing switch is available to
restore the day temperature of the
individual thermostat without
affecting the other system
thermostats. The indexing switch
can be unlatched manually or
will automatically reset with the
day cycle.
