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.

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.
