THE FLEXIBLE CONTROL
• Emerson TS1 Temperature Controls are designed to sense space
or surface temperature in cooling or heating applications for
cycling and alarm applications.
• Maximum application flexibility is provided by using a heavy-
duty 24-amp single pole double throw (SPDT) switch and
temperature ranges and power elements designed for specific
applications. The parts package includes a lockplate and knob,
which allows the user to lock both the range and differential
screws or the range or differential screw with a knob on the
unlocked screw.
FEATURES
• SPDT switch allows control of heating as well as cooling
applications.
• Heavy-Duty 24 Amp SPDT Switch allows the handling of most
loads directly without the use of a contactor.
• Non-Ambient Sensitive.
• 10 ft. capillary to provide maximum application flexibility.
• Standard accessories include mounting bracket and knob with
lockplate.
SAFETY INSTRUCTIONS
1. Read all Instructions thoroughly. Failure to comply can result
in control failure, system damage or personal injury.
2. Do not install in Hazardous Locations.
3. Disconnect electrical power before installation. Do not reapply
power until control installation is complete, wiring connections
secured and cover is in place.
Ambient Temperature Range: -58°F to +158°F
Temperature Range: See Control Label On Box

INSTALLATION INSTRUCTIONS
1. Cover Removal—Loosen cover screw and lift cover up.
2. Mounting—Mount the control in a protected area with the
included mounting bracket and screws, or on a flat surface
from the front.
CAUTION: If other screws are used, use 8-32 screws that
do not penetrate into the control more than 1/8’’.
3. Temperature Sensing Charges – Type & Application:
Three basic types of sensing elements are used on the TS
Series of controls, Vapor, Adsorption and Liquid.
Vapor Charge – Sensor Type A, E, P
These sensing elements always sense from the coldest point
on the capillary, coil, bulb or power element head. For proper
operation, it must be ensured that this coldest point is at the
sensor portion, which is exposed to the temperature to be
sensed. The sensing location should be at least 4°F (2 K)
colder than the other parts of the thermal system.
In order to avoid unwanted effects of heat transfer, e.g. from
a cold wall, Emerson vapor charged thermostats come with
an integrated bellows heater, which is rated for 230 V
applications. For other applications the heater must be
disabled, alternatively, a bellows heater with a different rating
may be available.
In addition to the bellows heater, room thermostats are
supplied with an insulation console for the same reason.
Vapor charges respond faster to temperature changes than
adsorption and liquid charges.
Adsorption Charge – Sensor Type F
Adsorption charged sensor types operate on the basis of a
temperature dependent adsorption material, which is located
inside the bulb only. Therefore these sensor types always
respond to temperature changes at the bulb only. This makes
them suitable to applications where it is not always defined
which part of the thermal system the coldest point is (cross
ambient applications). An example for such applications is
defrost control. Adsorption charges are slower in response to
temperature changes than vapor.
Liquid Charge – Sensor Type C
Liquid charge sensors of type 'C' always sense from the
warmest point of the thermal system. This condition must
always be ensured. The sensing location should always be
warmer than 4°F (2 K) than other parts of the thermal system.
4. Capillary Handling
• Sharp bends or kinks must be avoided in the capillary. Do
not allow capillary to rub and abrade against any moving
surface. Avoid any excessive handling or reforming to
minimize work hardening of the copper.
5. WARNING: Before making electrical connections, check with
a voltmeter as there could be more than one power source.
4. Electrical Connections – Make certain the load to be
connected is within the electrical ratings of the control.
• All wiring should conform to National Electrical Code
and local regulations. Use 14AWG or larger copper
conductors ONLY. See Switch Connection Diagrams later
in this installation instructions sheet.
• The terminals are of a clamp design. Loosen the terminal
screws with a Phillips head or small screwdriver, insert
approximately 3/8’’ stripped wire and tighten.
NEMA CLASS I – Mount the control body in an area
protected from the weather, water or excessive moisture,
dirt, dust and corrosive or explosive atmospheres.
