Introduction
The TS1 Series is ALCO's range of adjustable thermostats for
application in refrigeration and heat pump systems.
In these systems, thermostats serve control and monitoring
functions, such as space temperature control, high/low
temperature alarming or defrost termination. By operating a set
of electrical contacts, a temperature value is kept inside a
certain limit.
Several housing variants and sensors are provided in order to
suit a control to a specific application.
Housing variants
TS1 controls can be delivered in three main housing variants,
top operated, front operated and flush mounted.
Top operated controls have adjustment spindles at the top and
a display scale, indicating temperature setpoint and differential,
at the front. A knob which may be permanently plugged onto
one of the adjustment spindles comes with every control. Frost
monitors and room thermostats are derivatives of top operated
thermostats. They differ by their sensors and other features to
suit their particular target applications.
Front operated controls have an adjustment knob at the front for
the temperature setpoint with an approximate scale imprinted

the knob. In order to adjust the temperature differential, the
cover of the control must be removed.
Flush mounted controls are designed in a way that they can be
integrated into a panel or housing, for example into display
cases.
All of these three variants are available either with or without
off-switch, which cuts off power supply to the thermostat in off
position
Temperature sensing
TS1 thermostats sense temperature by means of a thermal
system, consisting of temperature charge, bulb, capillary and
bellows. The temperature charge changes its pressure based
on the refrigerant temperature to be sensed. The sensor is the
portion of the system which is in thermal contact with the
refrigerant, the capillary connects the sensor with the bellows
and the bellows contracts or expands depending on the
temperature, causing the thermostat to operate the electrical
contacts. An exception are capillary type of sensors, which do
not have a bulb, instead, their capillary serves as the bulb
directly.
