L6190A, B, C
AQUASTAT CONTROL
APPLICATION
The L6190 aquastat thermostat is sensitive water temperature
thermostat designed for surface mounting on domestic hot
water cylinders or pipe work.
The L6190 is delivered complete with mounting strap that
makes installation rapid and easy, since draining the system or
tapping the cylinder or pipe work is not required.
The SPDT switching action is accomplished by a snap action
micro switch actuated by the liquid in the temperature sensing
element.
The L6190 aquastat thermostat confirms with the following
EC directives:
Low Voltage Directive 73/23/EEC
Electro Magnetic Compatability Directive 89/336/EEC
Compliance with the EMC directive regarding emission can
only be determined in the application.
