Separate heatingand cooling set points and auto-changeover capability allowoccupied and unoccupied programming schedules forenergy savings.All thermostats allow up to 3 occupied and one un-occupied time/temperature setting to be programmed per24-hour period. Each thermostat stores programs for7 independent days. Batteries are not required. During powerinterruption the internal NEVERLOST™ memory stores pro-grams for an unlimited time.IMPORTANT: The thermostat has a configurable securitylevel. If certain functions are not available (changing setpoints, changing programming schedules), the thermostatsecurity level may be configured to exclude those func-tions. Call the installer to reconfigure the security level.A light sensor is provided on the thermostat for lightactivation. When the sensor detects light (the space isoccupied), the thermostat will enter into Occupied 1 mode.If the room is dark, the thermostat will follow its pro-grammed schedule.CONFIGURATIONThermostat Display — The thermostat display islocated in the center of the thermostat. See Fig. 1. The fol-lowing 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 indicatoris located on the bottom left cover of the thermostat. SeeFig. 2. The light will be red if the thermostat is in Heatingmode. The light will be green if the thermostat is in Coolingmode.Thermostat Front Panel Buttons — The thermo-stat has buttons on the front cover which are used to raise orlower the desired set point and override the current program.See Fig. 2.SET POINT BUTTONS — The UP ARROW and DOWNARROW buttons will raise or lower the current desired tem-perature set point. If the thermostat is in AUTO mode, press-ing the UP ARROW or DOWN ARROW buttons will adjustFig. 1 — Thermostat Display33CSCommercialProgrammable ThermostatManufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.Book 1 4Tab 11a 13aPC 111 Catalog No. 533-332 Printed in U.S.A.
