INSTALLATION INSTRUCTIONS
FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
This Hydraulic-Action temperature control is readily ap-
plicable for many types of commercial or industrial heat-
ing applications.
The speed of response of the temperature sensitive
element makes it particularly applicable to warehouses,
factories, garages and similar installations.
TYPE 2A37
HEATING
TEMPERATURE CONTROL
Adjustable Differential
When the temperature in the controlled area rises, the
fluid in the coiled element expands, causing the contacts
in the switch mechanism to snap open, turning off the
heating system.
As the air cools in the controlled area, the fluid in the coiled
element contracts. When the temperature drops to the
control setting, the contacts snap closed turning on the
heating system.

Summary
2 INSTALLATION The control may be mounted in any location provided thatthe temperature and humidity of the air in which it islocated will not cause a condensation on the switch parts. 1. The control should be mounted approximately six feet from the floor. 2. If the electric conduit goes to a warmer ...
3 SETTING THE CONTROL The movable indicator points to the temperature at whichthe contacts open. The fixed indicator points to the tem-perature at which the contacts close. The differencebetween these two indicators is the differential. To set the control: 1. Use a screwdriver in the adjusting slot ...
