Great Vintage Art Deco Sampsel Dual Setpoint Analog Clock Thermostat. If you are renovating an early Twentieth Century home and would like to incorporate a period item which also improves energy efficiency, I urge you to consider this thermostat. The clock circuit operates on a 24V 60Hz supply which is independent from the control contacts. Both the calibration and hysteresis are independently adjustable for each channel. In addition to it’s design purpose as a setback thermostat for heating control, it can also be configured as a heating and cooling thermostat. I will include the instructions with the item. An outstanding example of electromechanical design from the heyday of American manufacturing. International and next day options, see page for details. Any questions, please ask first. I respect your privacy, so if you prefer not to leave feedback I will also refrain. If you choose to do so, I will reciprocate.
