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.

High Volume Output
Thermostats

The high volume output
thermostats feature pneumatic
feedback and volume
amplification to provide fast and
accurate proportional response.
All models feature an output test
connection which can be used for
service and calibration.

A variety of covers (see Page 3)
and mounting accessories (see

Pneumatic Control Manual 717.1

Model Descriptions

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
respectively.

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 (see
Fig. 1). 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.

The T-4516 is also a dual
temperature, dual dial thermostat
for individual day and night
control or weekend setback.
Functionally it is similar to the
T-4506; however, it features an
additional output air terminal
which can be used as an on-off
switchline pressure. The manual
indexing switch is standard on
this thermostat. Depressing the
switch exhausts the switchline
pressure and restores day
operation of the individual
thermostat without affecting other
system thermostats. The switch
can be unlatched manually or will
automatically reset with the day
cycle.

The T-4756 is a dual temperature,
dual dial heating-cooling
thermostat which accomplishes
mode switchover between direct
and reverse actions, with a change
in supply pressure from 15 to
20 PSIG (105 to 140 kPa). An
energy conservation model is
available with factory stops to limit
the set points to 75°F (24°C)
maximum for heating and 75°F
minimum for cooling. This model
is furnished with WARM and COOL
dials.

Low Volume Output
Thermostats

The low volume output
thermostats employ a ball type,
force balance control port to
provide proportional feedback and
stable control. These thermostats
are electrically non-conductive
and allow test probe access
without removal of the cover.
Attractive low profile

covers are included with these
thermostats.

Model Descriptions

The T-4100 is a single
temperature thermostat. The unit
features exposed or concealed
set point adjustment and a
standard Fahrenheit and Celsius
thermometer. With the use of a
remote restrictor, this instrument
requires only one air connection.

The T-4110 is a single temperature
thermostat designed specifically for
mounting in ceiling terminal units.
This thermostat may be located
within a room air sampling
chamber, return air grille, or is
available with an optional
protective cover which incorporates
an aspirator feature to be powered
by the duct air pressure when
mounted in a diffuser. Available in
direct or reverse models, the unit
features a long flexible plastic
lever, connected to its set point
adjuster, which extends through the
ceiling or diffuser allowing
adjustment from inside a room.

The T-4600 is an energy manager
heating-cooling thermostat which
features two outputs and
individually adjustable
sensitivities and set points for
heating and cooling. Available in
dual direct, dual reverse, or direct
and reverse action models, the
independent set points can result
in a deadband to encourage
energy conservation and prevent
energy waste by eliminating
heating and cooling overlap
(see Fig. 2).

Note: All dual temperature
thermostats come equipped with
element identification labels
indicating the function of the
element.

Installation

Thermostat installation
procedures vary between the
high volume output and low
volume output units. Various
accessories are available (see
Table 1) to facilitate mounting
room thermostats on virtually
any wall surface. For a
complete list of accessory
repair parts, refer to Installation
Data T-4000-A.8.

All thermostats can be mounted
horizontally or vertically; air
connections are made with 5/32 in.
O.D. polytubing to barbed fittings
furnished on the units. Only high
volume output thermostats that do
not have manual indexing switches
can be concealed mounted with the
use of an aspirator wallbox and
flush wallplate. Other accessories
can be used for ceiling suspended
mounting. Several kits are also
available for converting existing
thermostats. For complete
mounting instructions, refer to
Installation Data T-4000-A.

Adjustment

The procedure for set point and
sensitivity adjustment depends on
the type of thermostat and method
of mounting. For detailed adjusting
instructions, refer to Adjustment
Data T-4000-B.
