Operating on a 24-volt control circuit, it handles one heat and one cool zone with a setpoint range of 50 to 90 degrees F. Mercury-free construction makes disposal simpler and keeps the unit compliant with environmental regulations in jurisdictions that restrict mercury-containing components. Licensed HVAC technicians and skilled service contractors are the typical installers. The unit measures 4.5 inches wide by 3.25 inches tall by 1.625 inches deep and provides a straightforward, no-frills interface suited for replacement work where simplicity and reliability matter.\u003c\/p\u003e\u003cp\u003eThis thermostat is suited for residential and light commercial applications using gas, oil, or electric heating and cooling systems. Its snap-action mechanism delivers a crisp switching response at the setpoint, reducing the risk of short-cycling. Terminal connections include RC, RH, W, Y, O, B, G, and A, covering conventional and heat-pump wiring configurations. This makes it a practical replacement candidate in a broad range of installed equipment. The manufacturer equivalent for this unit is listed as 1F56N-444.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNon-mercury snap-action switching — no mercury disposal concerns\u003c\/li\u003e\n\u003cli\u003e24-volt control circuit compatible with standard HVAC low-voltage systems\u003c\/li\u003e\n\u003cli\u003e1 heat \/ 1 cool single-stage control\u003c\/li\u003e\n\u003cli\u003eSetpoint range of 50 to 90 degrees F\u003c\/li\u003e\n\u003cli\u003eTerminal strip includes RC, RH, W, Y, O, B, G, and A for conventional and heat-pump wiring\u003c\/li\u003e\n\u003cli\u003eCompatible with gas, oil, and electric heating and cooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eListed as a replacement for part numbers 1F56-301 and 1F56-444.
