A device which senses "air or floor" temperature, controls operation of the heating source, and maintains the room temperature within the living space. Because of the effects of the heating system, the settings with hydronic radiant panel are 3-5°F lower than with forced warm-air for the same comfort level.

A device which automatically maintains a pre-determined temperature in an appliance. Thermostats can be of the "immersion" pattern where the actuating components are immersed in fluid whose temperature is to be controlled or of the "contact" pattern where the actuating components sense the fluids temperature through the wall of the container. The thermostats used in Dux electric units are of the "contact" type. Thermostats can be "snap acting", ie. operate from full-on to full-off and vice versa, or "modulating", operating gradually from full-on to a minium by-pass flow and vice versa. Some thermostats combine a modulating function from full onto low-fire, then snap action to off. The "differential" of snap-action thermostats is the temperature difference between the opening and closing functions. In the case of the thermostats used in Dux electric units the "differential" value is marked on the thermostat as "DIFF..".

An automatic device actuated by temperature changes designed to control the gas supply to the burner(s) in order to maintain temperature between predetermined limits, and in which the thermal actuating element is an integral part of the device: 1. Electric Switch Type: A device which senses changes in temperature and control electrically, by means of separate components, the flow of gas to the burner(s) to maintain selected temperature. 2. Graduating Thermostat: A thermostat in which the motion of the thermostat valve is in direct proportion to the effective motion of the thermal element induced by temperature change. 3. Quick-Acting Graduating Thermostat: A thermostat which changes from the completely closed position, or vice versa, but not with a snap. 4. Snap-Acting Thermostat: A thermostat in which the thermostatic valve travels instantly from the closed to the open position, or vice versa.

A temperature sensitive device used to control HVAC systems.

( See it) The way the HydraTherm heating system controls the temperature in the pond is by the insertion of a thermostat sensor into the HydraTherms "well" - Water flows around the well in the HydraTherm jacket and is measured by the sensor. The thermostat is simply wired to the Circulator Pump ( See it). When the temperature is too low, the thermostat cuts ON the circulator, which starts taking DANG HOT water from the boiler, pumps it through the "A-side" of the Exchanger. Another pump is *always* pumping cool pond water through the "B-side" and the two waters meet through stainless steel.
