Programmable Thermostat

This non-programmable digital fan coil thermostat is designed for 2-pipe HVAC systems requiring reliable temperature control in commercial and residential applications. Compatible with Honeywell Thermal Solutions TB6575B1000/U specifications, this replacement unit operates on either 120 VAC or 240 VAC supply (+/-10% at 50/60 Hz), providing flexible installation options across various facility types. The thermostat delivers 1 heat/1 cool (1H/1C) control with a convenient 3-speed fan setting and manual/auto heat/cool changeover functionality. Its onboard temperature sensor features a 10K NTC thermistor with a working range of 0 to 120 degrees Fahrenheit (18 to 49 degrees Celsius) and a display range of 32 to 99 degrees Fahrenheit (0 to 37 degrees Celsius), ensuring accurate temperature monitoring with +/-2.0 degrees Fahrenheit accuracy at 70 degrees Fahrenheit. For expanded flexibility, an optional remote indoor sensor using a 20K NTC (Type 42) thermistor is available with identical range and accuracy specifications. Contact ratings accommodate various applications: fan relays handle up to 6.0 amperes at 120 VAC or 3.0 amperes at 240 VAC, while heat/cool relays are rated for 1.0 ampere across all voltage levels. This unit is ideal for facility managers seeking straightforward, dependable temperature regulation without complex programming requirements. The digital display provides clear, real-time temperature readouts for easy monitoring and manual adjustment in schools, offices, hotels, and institutional settings where simple, efficient climate control is essential.
