Reliable Control Over Basic Air Conditioner Functions
Electro-mechanical rotary-knob switch assemblies provide conventional control over basic air conditioning functions. Both 115V and 230V switches are available. The standard design is an aluminum plate covered with a modern black plastic overlay with text and graphical representations of the various functions. Many different configurations are available:
Standard three-knob assemblies provide function selection (OFF-FAN-RUN), fan speed control, and a room thermostat with 10 ft. (3 m) capillary tube. For chilled water systems, a special thermostat on the air handler allows automatic changeover between heating and cooling modes.
Switches are also available for use with auxiliary heat modules, but an HRX type heat relay may be needed in certain cases.
