TP970 and TP9600 Series

Pneumatic Thermostats

SERVICE DATA

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, pilotbleed, 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

TP973A,B and TP9630A,B

The TP973A, B and TP9630A,B are one- or two-pipe bleedtype 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.

The TP972A and TP9620A are single-temperature, pilotbleed, 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).

OPERATION

TP970A,B and TP9600A,B

When using a TP970A or TP9600A (Fig. 1) in heating applications with a normally open valve, a fall in temperature lowers Branchline Pressure (BLP) to the valve. THis lower BLP provides proportional valve action matching the existing load requirements. When a TP970B or TP9600B is used in a cooling application, a rise in temperature causes the TP970B or TP9600B to lower BLP. The energy conservation models limit control temperature to a maximum (heating) or minimum (cooling) of 72F (24C).
