The Trane Schlage Link TZEMT400BB32MAA is a Z-Wave enabled thermostat for controlling heating and cooling HVAC systems. It provides typical thermostat control with Z-Wave™ RF communications for remote access via Schlage LiNK™ integration. Features include a graphical LCD display, 7-day programmable scheduling with 4 periods per day, energy-saving modes, and compatibility with single/multistage forced air systems. Below are the key specifications and operation instructions.
1. Set the Clock: Press MENU, scroll to User Settings, select Set Clock. Adjust hour, minute, AM/PM, month, day, year, and day of week using +/− buttons, then press Set to save.
2. Calibrate Sensor: MENU > User Settings > Sensor Calibration (±7°F).
3. Enable Scheduling: In Installer Settings > System Settings > Sched Enable (Y to enable).
4. Z-Wave Integration: Perform inclusion (see Advanced Features).
5. Set Initial Mode: Press Mode for Off/Heat/Cool/Auto; Fan for Auto/On.
6. Adjust Setpoints: Use Up/Down buttons (maintains 3°F minimum separation).
1. Display: Clock (upper left; blinks if unset), ambient temperature, heat/cool setpoints, system status (e.g., Sys Off, Run, Filter), dynamic labels above/below 6 buttons.
2. Function Control Buttons:
| Button | Description |
|---|---|
| Menu | Access menus (User Settings, Usage Graph, ESM Setpoints, ZWave Install, Thermostat Info, Installer Settings [hidden], Schedules [disabled by default]) |
| System Mode | Change to Off (system off), Heating (heating only), Cooling (cooling only), Auto (heating/cooling as needed) |
| Fan Mode | Change to Auto (fan on when heating/cooling needed) or On (fan constant) |
| Schedule Mode | Change to Hold (maintain current setpoints, ignore schedules), Run (follow schedule or Z-Wave schedule), Energy Saving Mode (use ESM setpoints) |
Scheduling is disabled by default (controlled by Z-Wave); enable in Installer Settings (Sched Enable: Y). Supports 4 periods per day (Wake, Day, Eve, Sleep) for 7 days, with separate heat/cool setpoints.
1. Enable/Disable Schedules: In Installer Settings > System Settings > Sched Enable (Y to enable, N to disable).
2. Load Preset Schedule: Press MENU > Schedules > Select Heat and Cool or Preset. Choose Preset: Comfort (mild setbacks) or Energy Star (deeper setbacks). Press Yes to load (overwrites current).
3. View Current Schedule: Press MENU > Schedules > Heat and Cool. Current day displays; press Next for other days.
4. Set Heat/Cool Schedule: Press MENU > Schedules > Heat and Cool. For current day, use left/right arrows to select item (time, heat/cool setpoint), adjust with +/−. Press Next for other days.
5. Copy a Day Schedule: In Heat and Cool schedule, highlight small "c" with left arrow to show Copy button. Press Copy, set Y/N for target days using arrows and Yes/No buttons, then Copy.
6. Recovery: If enabled, starts system early to reach setpoint by schedule time (max 1 hour, displays "Recov"; no aux heat).
Access via MENU > User Settings (or Installer Settings: hold two middle buttons).
