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. Free Priority Mail

Shipping to your eBay/PayPal verified

address. 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. I may have other listings, feel

free to check the "See other items" link at the upper right.


Thank you for your interest!
