The Marley M601W thermostat is adjusted using a large knob that allows for easy temperature control. These thermostats are built to adjust temperatures within 45 to 75 degrees Fahrenheit. Qmark thermostats have different ranges and switches for adjusting the temperature, as well as different temperature sensitivities.
Thermostats function by detecting the temperature in a room, typically by reading changes in thermometers built into them or inserted in strategic places throughout the house. If the Marley M601W thermostat is not working properly, the thermometer inside it may be obstructed or receiving poor detections.
Adjusting the temperature on a thermostat is sometimes done using manual switches and knobs, but many modern thermostats use digital pads for their input. Once the thermostat is programmed, use the pad to adjust the settings or to perform other functions for which the thermostat is designed. Some digital thermostats are programmable to adjust the temperature according to the time of day, or to provide different adjustments according to the heating or cooling requirements of a given room.
Some thermostats are built with controls not found in residential settings. Commercial thermostats may be built with pnuematic functionality, which adjusts the temperature according to shifts in air pressure instead of electrical signals.
