Manufacturer: Johnson Controls

Description: PROP THERMOSTAT 50ft CAP

Category: Thermostats

Proportional and Two-Position
Remote Element Controllers

The T-8000 Remote Element

Thermostat is designed for

applications which require the

sensing element to be located

where extreme conditions do not

permit controller mounting, or

where operational adjustments

to the controller would be

inconvenient. This high volume

(output) instrument is ideally

suited for installations that

require the controller to be

mounted on a local control


The thermostat can be made to

function as a direct or reverse

acting instrument by changing

position of the patented sliding

control port. Repositioning the

control port will also change

sensitivity on proportional

models and differential on

two-position models.


As the temperature at the

measuring element increases or

decreases, the liquid in the

element expands or contracts at

a linear rate. This will cause the

system of flexure levers to open

or close the control port. For a

direct acting instrument, the

sliding control port should be

positioned above the mid-point

on the slider rail. For a reverse

acting instrument, the slider

control port should be positioned

below the mid-point on the slider

rail. The rail is marked DA

(Direct Acting) at the top and RA

(Reverse Acting) at the bottom.

Moving the slider upward from

the mid-point on the rail

increases sensitivity and

decreases differential for direct

acting applications. Moving the

slider downward from the midpoint

on the rail increases the sensitivity and decreases

differential for reverse acting



The T-8000 is designed for

surface mounting with barbed

fittings provided for air

connections. Position of the

measuring element will not affect

operation of the instrument.
