The Programmable Commercial Thermostat by Honeywell is designed to integrate conventional and heat pump systems and offers three stages of heating and cooling. Its advanced capabilities come with a HEAT-OFF-COOL-AUTO-EM.HEAT switching function and AUTO-ON fan switch positions, visible through a straightforward display.

Equipped with 365-day programming, the thermostat provides flexibility and precision on energy management. An exceptional feature is its auxiliary contact interface, which can liaise directly with a Honeywell Economizer System or function as a dehumidification output. The device supports four periods per day, divided into two occupied and two unoccupied spans.

The thermostat interface module connection allows advanced configuration and programming from a PDA and contributes to the control of the keypad and lockout. Individual heat and cool set points can be adjusted during both occupied and unoccupied periods,

For optimal comfort, the thermostat incorporates P+|+D control, minimizing temperature fluctuations and ensuring steady environmental conditions. In addition, the Recovery Ramping Control automatically enhances equipment start times based on the building's load, ensuring efficiency and reliability.

Designed to withstand everyday use, the thermostat is compatible with Honeywell's Universal Versaguard Thermostat Guards. It offers convenient overrides that allow for temporary set point changes. All models of these thermostats come with a multi-level keypad lockout feature, emphasizing essential security features and preventing unintentional programming changes.
