Operating on 24 volts hardwired power or battery backup, it provides reliable temperature regulation across a control range of 44 degrees F to 90 degrees F with a display range of 41 degrees F to 95 degrees F. Dedicated B and O terminals support standard heat pump wiring configurations, and separate heating and cooling swing adjustments allow fine-tuned performance. Push-button operation keeps the interface straightforward, making the T721 a practical choice for contractors installing non-programmable climate control in heat pump applications.\u003c\/p\u003e\n\u003cp\u003eThe T721 is suited for residential and light commercial heat pump installations where 2-stage heating and 1-stage cooling staging is required. It mounts to a standard wall surface or junction box, accommodating a variety of rough-in conditions. Configurable settings support electric or gas auxiliary heat sources, extending its usefulness across different heat pump system configurations. The unit is appropriate for HVAC technicians handling retrofit or new-installation work where programming capability is not required by the end user.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-stage heating and 1-stage cooling staging for multi-stage heat pump systems\u003c\/li\u003e\n  \u003cli\u003eOperates on 24-volt hardwired power or battery, supporting a wide range of wiring scenarios\u003c\/li\u003e\n  \u003cli\u003eDedicated B and O terminals for standard heat pump reversing valve control\u003c\/li\u003e\n  \u003cli\u003eControl temperature range of 44 degrees F to 90 degrees F with display range of 41 degrees F to 95 degrees F\u003c\/li\u003e\n  \u003cli\u003eMounts to wall surface or junction box for flexible installation\u003c\/li\u003e\n  \u003cli\u003eNon-programmable push-button interface reduces end-user complexity\u003c\/li\u003e\n  \u003cli\u003eRated for up to 90% non-condensing relative humidity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation thermostat for multi-stage heat pump systems requiring 2-stage heating and 1-stage cooling control with 24-volt low-voltage wiring.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with local codes and the system manufacturer guidelines. Power down the air handler and outdoor unit at the disconnect and breaker before removing the existing thermostat or making any wiring connections. Verify wire labeling at the old thermostat base before disconnecting to avoid wiring errors at the new sub-base. Battery insertion or hardwired 24-volt connection should be confirmed before powering the system back up and testing each stage of operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Thermostat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Multi-Stage Heat Pump\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStages\u003c\/strong\u003e: 2 Heat \/ 1 Cool\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Method\u003c\/strong\u003e: Hardwired or Battery\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Temperature Range\u003c\/strong\u003e: 44 degrees F to 90 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay Range\u003c\/strong\u003e: 41 degrees F to 95 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Humidity\u003c\/strong\u003e: 90% non-condensing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProgrammability\u003c\/strong\u003e: Non-Programmable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUser Interface\u003c\/strong\u003e: Push Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount\u003c\/strong\u003e: Wall or Junction Box\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LID CORPORATION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T721\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LID CORPORATION","offers":[{"title":"Default Title","offer_id":51620996612402,"sku":"T721","price":96.93,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bf55ad239503ef855abdfcce0bb957c.jpg?v=1787348342","url":"https:\/\/voomisupply.com\/products\/lid-corporation-t721-non-programmable-heat-pump-thermostat","provider":"Voomi Supply","version":"1.0","type":"link"}
