The cover and faceplate design makes the thermostat adaptable to any decor. The thermostats have a sturdy steel cover with a tawny silver finish. The faceplates are dark brown and light brown with aluminum numbers and graduation marks.
The liquid charged sensing element's design achieves maximum sensitivity to ambient air temperature changes. See Figure 2. The element, together with a highly efficient diaphragm and leverage mechanism, operates a totally enclosed Pennswitch contact unit. The thermostat features a close differential and dependable switching action without the use of heat or cool anticipators.
The thermostats are more versatile without anticipators. You can use them on heating or cooling over a wide range of current loads, either on 120 V or 240 V systems.
All types are available on special order with concealed adjustments for the temperature setting and selector switch. All thermostats are equipped with Allen head cover screws.
These thermostats have a concealed high temperature stop with adjustments in 2°F (1.1°C) increments between 68°F and 80°F (20°C and 27°C).
