Uni-Stat IIa 120 Volt Digital Temperature Controller

Uni-Stat IIa 120 Volt Digital Temperature Controller with Heat and Cool Mode Selector. Whether controlling a refrigerator, or running a small pump with a cooling coil, for fermentation temperature control; or, for heating with a 120V element or heating pad, you won't find a more effective or easier-to-use digital controller than this one - and no programming required! A unique 'Duty Cycle' feature provides for optimally smooth temperature control of either cooling or heating modes. Made in the USA, with a 3-Year factory Warranty! Some applications include: low-cost wine or beer storage, wine-making, beer-brewing fermentation, RIMS or BIAB regulation, and many other applications! CHARACTERISTICS and SPECIFICATIONS: · Plugs directly into 120VAC wall receptacle, or a 3-wire 15A grounded extension cord or power strip; then your 120VAC cooler or heater rated 13 amps or less (about 1500 Watts max) plugs into the UNI-STAT IIa front receptacle. No programming required. · Set the MODE switch for either COOL or HEAT mode, then adjust the desired temperature with the convenient toggle switch to maintain within 1°F, which is continuously displayed. Temperature selection and display is from 10° to 220°F · Plug the replaceable 8′ temperature probe into the UNI-STAT IIa, with the sensing element at the location to be controlled. Suitable for 1/4″ thermowell installation. · For optimum energy efficiency, set the DUTY CYCLE switch to 50% while unit is operating to maintain selected temperature. 50% cycle is 10 minutes ON, 10 minutes OFF in COOL mode (5 minutes ON, 5 minutes OFF in HEAT mode), then repeat, until the desired temperature is achieved and your unit is shut off. · Automatic sensor fault detection with visual flashing alarm and automatic system shut-off · Compressor protection feature in COOL mode, to prevent possible "short-cycling" damage · Automatic flashing ALARM activates if temperature exceeds set-point by 5° or more
