Honeywell PRO22ENC3 Programmable thermostat

Product Detailed Description:

The Honeywell PRO22ENC3 is a programmable thermostat designed for residential heating and cooling systems. It allows users to set different temperature schedules throughout the day and week, helping to maintain comfort while potentially saving energy. This model typically features an easy-to-read display, simple navigation buttons, and the ability to program up to four distinct periods per day for both heating and cooling setpoints. It is designed to replace older, non-programmable thermostats and offers basic programmability without the complexity or connectivity features of smart thermostats. The “ENC3” designation might relate to specific packaging or features like a protective cover.

Product Parameters:

(Note: Specific values can vary slightly depending on the exact version and region. Always refer to the datasheet for precise details.)

• Power Source: Typically 24 VAC, neutral connection (supplied by the heating/cooling system).

• Display: Usually a backlit LCD display showing temperature, mode, and schedule status.

• Programming:

• Programmable for both heating and cooling.

• Typically allows for 4 periods per day (e.g., Wake, Leave, Return, Sleep).

• Programs can usually be set for weekdays and weekends, or fully customizable for each day of the week.

• Features like “Hold” to temporarily override the schedule and “Vacation” mode for extended absences.

• Temperature Sensor: Built-in ambient temperature sensor.

• Compatibility: Designed for use with standard single-stage or limited multi-stage heating and cooling systems (e.g., furnaces, air conditioners, heat pumps with auxiliary/emergency heat). May not be compatible with all heat pump configurations or multi-stage systems without specific wiring considerations.

• Installation: Wall-mounted, designed for standard electrical box sizes. Includes mounting plate and screws.

• Dimensions: Refer to datasheet for exact width, height, and depth.

• Certifications: Likely UL Listed, cUL Listed, CE Marked (check packaging/datasheet for specific marks).

Product Advantages:

• Energy Savings: Programming allows the system to adjust temperatures automatically when heating/cooling is not needed (e.g., when away or sleeping), potentially reducing energy consumption and utility bills.

• Enhanced Comfort: Maintains desired temperatures automatically throughout the day according to the programmed schedule, reducing the need for manual adjustments.

• Convenience: Eliminates the need to remember to adjust the thermostat manually; the schedule runs automatically.

• Easy Programming: Typically features straightforward buttons and menus for setting up and modifying the schedule.

• Reliable Operation: Honeywell is a well-established brand known for durable and reliable home comfort controls.

• Simple Replacement: Designed for easy installation as a direct replacement for many older mechanical or non-programmable thermostats.

Precautions / Notes:

• Compatibility Check: Before installation, carefully verify compatibility with your specific heating and cooling equipment (furnace, air conditioner, heat pump type). Incorrect compatibility can lead to equipment damage or improper operation. Consult the thermostat manual and equipment documentation.

• Proper Wiring: Incorrect wiring can damage the thermostat, the HVAC system, or cause safety hazards. If unsure, consult a qualified HVAC technician or electrician. Pay special attention to connections like the “C” (common) wire if required by your system or if using future add-ons.

• Installation Environment: Install in a location away from direct sunlight, drafts, heat sources (like lamps or appliances), or cold spots (like windows or exterior walls) to ensure accurate temperature sensing.

• Battery Backup: This model typically relies on the 24VAC system power and may not have a long-lasting battery backup. Power outages will reset the schedule or require reconfiguration.

• Read the Manual: Thoroughly read and understand the installation and operation manual before installing or using the thermostat.

Product Applications:

• Residential Heating and Cooling Control: The primary application is to control the temperature in single-family homes, apartments, condos, and other residential dwellings.

• Single-Stage Systems: Ideal for controlling basic furnaces, air conditioners, and some heat pump systems.

• Limited Multi-Stage Systems: May be compatible with certain limited multi-stage systems, but verify compatibility.

• Replacing Older Thermostats: A common use is upgrading from manual or non-programmable thermostats to gain scheduling benefits.

• Small Offices or Workshops: Can also be suitable for small commercial spaces with compatible HVAC systems.
