Resumen del manual
GENERAL Carrier’s 7-day, commercial, programmable thermostats are wall-mounted, low-voltage thermostats which maintain room temperature by controlling the operation of an HVAC (heating, cooling and ventilation) system. Separate heating and cooling set points and auto-changeover capability allow occupied and unoccupied programming schedules for energy savings. All thermostats allow up to 3 occupied and one unoccupied time/temperature setting to be programmed per 24-hour period. Each thermostat stores programs for 7 independent days. Batteries are not required. During power interruption the internal NEVERLOST™ memory stores programs for an unlimited time. IMPORTANT: The thermostat has a configurable security level. If certain functions are not available (changing set points, changing programming schedules), the thermostat security level may be configured to exclude those functions. Call the installer to reconfigure the security level. CONFIGURATION Thermostat Display — The thermostat display is located in the center of the thermostat. See Fig. 1. The following information can be displayed on the screen: • mode (OFF, HEAT, COOL, AUTO, or PROGRAM ON) • fan setting (FAN ON or blank) • override indication • room temperature • desired temperature • service filter indicator • time of day • day of the week • schedule period (Occupied 1, 2, or 3; or Unoccupied) • setup indicator (programming mode) • lock indicator • start/stop indicator (schedule period program mode) Heat or Cool Indicator — A Heat or Cool indicator is located on the bottom left cover of the thermostat. See Fig. 2. The light will be red if the thermostat is in Heating mode. The light will be green if the thermostat is in Cooling mode.

Thirty minutes of override time will be added for each time the Override button is pressed up to a maximum of 4 hours.
