The Amana PHWT-A200 Electronic Wall Thermostat is the premium commercial solution for hardwired 24V climate management in hospitality, multi-family, and senior living properties. Engineered for maximum versatility, this dual-mode thermostat operates as either a 7-day programmable unit (supporting 1, 2, or 4 daily schedule periods) or a manual non-programmable thermostat.
Designed for 2-stage heating and 2-stage cooling across both conventional electric heat (PTC series) and heat pump (PTH/HEH series) PTAC units, the PHWT-A200 features a large 4.25-inch backlit display, Auto Changeover, and a patented Thermal Intrusion Barrier. Built-in property management controls—including field-adjustable maximum heat and minimum cool limits—prevent equipment abuse and slash building energy overhead.
Replacement & System Note: Directly replaces legacy Amana models 2246007 and 2246008. A low-voltage wiring harness is required for all new remote wall thermostat installations. When paired with Amana Through-the-Wall CC model units, the PBTCK01 control kit is required.

Versatile Programmable & Manual Dual-Mode Operation
Whether you need automated 7-day schedule setback for multi-family apartment developments or intuitive manual operation for high-turnover hotel guest rooms, the Amana PHWT-A200 Hardwired Wall Thermostat satisfies both requirements. Property managers can configure the unit for up to 4 programmable time periods per day (Morning, Daytime, Evening, Night), 2 periods (Daytime, Nighttime), 1 period, or completely disable programming for simplified manual guest use.
Advanced 2-Stage Heat / 2-Stage Cool Engineering
The PHWT-A200 provides advanced multi-stage temperature management across commercial HVAC configurations:
Heat Pump PTACs (PTH / HEH Series): Supports 2-Stage Heat / 2-Stage Cool operation. Utilizes compressor heat pump operation for primary energy-efficient heating and engages auxiliary electric heat strips when ambient temperatures drop.
Conventional Electric Heat PTACs (PTC Series): Delivers multi-stage control for electric resistance heating and compressor cooling.
Through-the-Wall Units (CC Series): Fully compatible with Amana CC series units when installed with the optional Amana PBTCK01 control kit.
Energy Management & Thermal Accuracy Features
Patented Thermal Intrusion Barrier: Isolates the internal sensor from cold or warm air drafts residing inside wall cavity cutouts, ensuring +/- 1°F temperature control accuracy.
Auto Changeover Mode: Automatically toggles between heating and cooling modes as room conditions fluctuate, eliminating manual seasonal adjustments (can be disabled in installer settings).
Adjustable Temperature Set-Point Limits: Property managers can set strict maximum heat (e.g., 72°F) and minimum cool (e.g., 68°F) thresholds to restrict excessive utility usage.
Dedicated Remote Sensor Terminals (S1 / S2): Features hardwired terminals to connect optional indoor or outdoor remote temperature thermistors.
Programmable or Manual Flexibility: Easily switches between 7-day automated scheduling and simple push-button manual operation.
Slashes Utility Costs: Configurable maximum heat and minimum cool limits prevent tenants or guests from over-indexing heating or cooling.
Automated Seasonal Transition: Auto Changeover seamlessly switches between heat and cool modes to maintain stable room comfort.
Eliminates Draft Sensor Errors: Patented Thermal Intrusion Barrier seals wall openings behind the plate to ensure accurate temperature sensing.
Hardwired 24 VAC Power: Eliminates battery replacements and service calls across multi-room facilities.
Large 4.25-Inch Backlit Screen: High-visibility digital readout displaying current room temperature, target set-point, and fan status.
2-Speed Fan Management: Push-button and slide settings for AUTO, LOW, and HIGH fan blower operations.
2-Stage Heat / 2-Stage Cool Capability: Fully supports multi-stage compressors and auxiliary heat strips.
Dedicated Remote Sensor Terminals: Terminal connections (S1/S2) for optional remote indoor/outdoor temperature sensors.
Auto Daylight Savings Time: Automatically adjusts internal clock settings twice per year.
Field Adjustable Calibration: Allows facility engineers to calibrate room temperature readouts (+/- 1°F / +/- 0.5°C).
