LID Corporation Non Programmable Thermostats

Overview

The LID CORPORATION T721 is a digital non-programmable thermostat engineered for multi-stage heat pump systems requiring 2-stage heating and 1-stage cooling control. 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. The 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.
