TP970 and TP9600 Series
Pneumatic Thermostats
75-7134-1
GENERAL
The TP970 and TP9600 Series Pneumatic Thermostats are
one-, two-, or three-pipe, proportioning thermostats with
bimetal elements. They are suitable for controlling dampers
and/or valves in HVAC systems.
APPLICATION
TP970A-D and TP9600A,B
The TP970 and TP9600 are single-temperature, pilot-bleed,
two-pipe thermostats. The TP970A and TP9600A are used for
heating (Direct Acting [DA]), the TP970B and the TP9600B for
cooling (Reverse Acting [RA]), and the TP970C and D for
heating/cooling. There are TP970A and B models with Limited
Control Range (LCR) for energy conservation. The TP970C
and D have a wide throttling range capability, allowing an
adjustable Zero Energy Band (ZEB) between heating and
cooling operations.
TP971A-E and TP9610A,B
The TP971A-E and TP9610A,B are two-temperature, pilot-
bleed, two-pipe thermostats for DAY/NITE operation, with
automatic switchover from mainline pressure. The TP971C is
a three-pipe thermostat for unit ventilator DAY/NITE
application.
TP972A and TP9620A
The TP972A and TP9620A are single-temperature, pilot-
bleed, two-pipe thermostats with cooling/heating cycles and
automatic switchover from mainline pressure. The
TP972A2143 is designed specifically for replacing Johnson
cooling/heating thermostats (see SPECIFICATIONS section).
TP973A,B and TP9630A,B
The TP973A, B and TP9630A,B are one- or two-pipe bleed-
type thermostats for heating or cooling applications.
TP974A
The TP974A is a pneumatic space temperature sensor for
either one- or two-pipe applications. It is suitable as a remote
temperature indicator or as the sensor for a receiver
controller.
TP978A-E
The TP978 is a dual-element bleed-type thermostat used in
dual one-pipe applications, suitable for use with variable
volume systems. These thermostats may be used to control
separate heating and cooling actuators in sequence, with a
Zero Energy Band (ZEB) for energy conservation. The
heating setpoint is limited to 73F (23C) maximum, and the
cooling setpoint is limited to 77F (25C) minimum. Heating and
cooling are available in both DA and RA configurations.
Except for the TP978E, there are no upgraded replacements
for the TP978.
TP979A-E
The TP979 contains two cooling/heating, DAY/NITE
thermostats. They are one- or two-temperature, two-pipe
thermostats for independent proportioning control of heating
and cooling.
