Architectural Specifications
The universal auto changeover thermostat is the Braeburn® model number 4220. It measures 3.86" high x 5.11" wide x 1.42" deep. It is powered by either 24 Volt AC or two "AA" Alkaline batteries (3.0 Volt DC). In the event of a power failure, the unit retains all user, installer, and program settings.
The thermostat is compatible with low voltage single stage or multi-stage gas, oil, or electric conventional heating or cooling systems with up to two stages of heating and two stages of cooling. It is also compatible with heat pump systems with up to three stages of heating and two stages of cooling. Additionally, it supports 250mv-750mv millivolt heating only systems and 2 or 3 wire hydronic zone systems.
Key features include a bright blue backlight display, a separate sub-base, and multi-level keypad lockout. The temperature control range is between 45° and 90° F (7° and 32° C), with an accuracy of +/- 1° F (+/- .5° C). The operating humidity range is between 5% and 95% relative humidity.
The thermostat includes separate installer and user setup modes, residential or commercial setup modes, permanent non-volatile memory for user settings, filter, UV and humidifier pad check monitors, adaptive recovery mode (ARM™), programmable fan mode, residual cooling fan delay, indoor or outdoor remote sensor capability, auxiliary heat fossil fuel programming, and compressor power outage protection. A front reset button returns user settings to default values when pressed. It meets Energy Aware® Guidelines.
