The Trane X13511538-01 (BAYSTAT152A) is a touch-screen programmable thermostat for conventional rooftop units (RTU) air conditioners and heat pumps. It features an LCD touch screen, support for 1-3H/1-2C stages, scheduling (2/4 periods, 1/5+1+1/5+2/7-day), temporary overrides (TOV), dehumidification, economizer/TOD control, remote sensors, and lockout features. Below are the key specifications and operation instructions.
1. Power On: Apply 24 VAC; performs self-test, displays errors if any (e.g., E1 low voltage).
2. Set Time/Date: Touch clock icon; adjust hours/minutes/day/month/year; save.
3. Set Mode/Fan: Touch mode/fan icons; select Heat/Cool/Off/Auto/Em Heat and Auto/On.
4. Installer Config: Access menu for initial options (e.g., temp units, system type).
1. Display: Current temp, setpoints, time/day, mode icons, occupancy, filter/error alerts.
2. Controls: Touch arrows for setpoints; mode/fan boxes for selection; menu for settings.
3. Indicators: Flame/snowflake for active modes; blinking filter/error; hourglass for TOV.
1. Heat: Select Heat; raise setpoint with arrows; activates stages with flame icon.
2. Cool: Select Cool; lower setpoint; activates stages with snowflake icon.
3. Auto: Automatic heat/cool changeover (manual/auto via config).

2. Schedule: Set periods (2/4), day groups; adjust time/heat/cool/fan/occupancy per period.
3. Filter Reset: Hold arrows 3s.
4. Offsets: Adjust temp/humidity (±6°F/°C).
5. Lockout: Requires code (default 0000) for changes.
1. TOV: Touch fan box; quick (up to 4 hrs) or configurable (0.5-8 hrs); shows remaining time.
2. Dehumidification: Enable via config; controls with remote sensor.
3. CPH/Lockouts: Cycles per hour (1-10); temp-based compressor/aux lockout (40-70°F).
