Light Activatin Operatin A light sensr is prvided n the thermstat fr light activatin. The thermstat must be in the Prgram On mde fr light activatin t wrk. When the sensr detects light the thermstat enters the Occupied 1 time perid and will heat r cl accrding t the Occupied 1 setpints. If the rm is dark the thermstat will fllw its prgrammed schedule. Since light will put the thermstat int Occupied 1, and darkness will release the thermstat t fllw its prgrammed schedule, it is recmmended t turn OFF Occupied 1 in the time perid prgramming, see page 10. If Occupied 1 is turned OFF, then when the rm is dark the thermstat will enter Unccupied energy savings settings. Occupied 2 r 3 may be used as a pre-cl r pre-heat perid in cnjunctin with light activatin. Fr example: An ffice that is usually ccupied 9:00am - 5:00pm, Mnday thrugh Friday. Occupied 2 can be set 8:30am - 9:00am Mnday thrugh Friday with cmfrt setpints. If n ne turns the lights n by 9:00am then the thermstat will enter the Unccupied time perid and prvide energy savings. Occupied 1 has pririty ver Occupied 2, which has pririty ver Occupied 3. This allws Occupied 2 t run in the backgrund, and when the lights are n, Occupied 1 setpints takever. This added flexibility allws, fr example, Occupied 2 t be prgrammed in the ffice envirnment t run Mnday - Friday, 8:00am - 5:00pm. The setpints can be set t allw fr energy savings shrt f Unccupied settings. If the lights g ff during the wrkday, such as lunchtime, when returning, the recvery wuld be shrter. The Occupied 1 will flash if the light sensr is cause f the thermstat t be in Occupied 1. Page 8

PROGRAMMING NOTES N We C Py If N is selected: If nly 1 Occupied perid is selected in step 1 n page 9, Occupied 2 & 3 prgramming steps are skipped. Further, if nly 2 ccupieds are selected, Occupied 3 prgramming steps are skipped. Heat & Cl setpints fr Occupied 1 are the same fr every day f the week. Heat & Cl setpints fr Occupied 2 & 3 can be adjusted differently fr each day f the week, if desired. If the start time is set later in the day than the stp time, the prgram will run frm the start time t midnight and frm midnight t the stp time n the same day. Fr example: 9:00pm start, 8:00am stp, n Mnday. In this example the prgram will run frm 12:00am Mnday t 8:00am Mnday and again frm 9:00pm Mnday t 12:00pm Mnday. The Unccupied settings take effect at all times when: (1) the prgram is n and (2) the current time is utside a preset ccupied perid. Fr this reasn start and stp times aren t necessary fr unccupied. If the same start and stp times are prgrammed in fr an ccupied perid, then it will run 24 hurs. If ne ccupied perid starts and stps within anther ccupied perid the lwer ccupied # has pririty. Fr example: If Occupied 3 is prgrammed t be n 24 hurs, and Occupied 2 is prgrammed t run that day, then Occupied 2 settings will take ver frm ccupied 3 between Occupied 2 start and stp times. Page 12

Abut Advanced Features & Operatin DUAL SETPOINT BEHAVIOR - The adjustable setpint range is: 35-99 degrees in Fahrenheit and 7-35 degrees in Centigrade. When in the mdes Heat r Cl, this adjustable range is unhampered. When adjusting any Aut mde, including prgramming Occupied and Unccupied perids, the thermstat will nt allw the Heat setpint t get clser t the Cl setpint than the value prgrammed as the minimum difference in step 6, page 13. When entering the Aut mde frm Cl, the Heat and Cl setpints will remain spread apart by the amunt that they were adjusted, prir t entering Aut. Fr example: If the Cl setpint was set t 80 while in the Cl mde and the Heat setpint was adjusted t 70 while in the Heat mde, upn entering the Aut mde the Heat and Cl setpints wuld be 80 and 70. Bth setpints wuld then mve up and dwn tgether, (in this example spread by 10 degrees), by pressing the up r dwn buttns. T mve the Heat and Cl setpints clser tgether, enter the Cl r Heat mde by pressing the Mde buttn, then adjust the setpint(s) clser tgether. Heat is limited t hw clse it can cme t Cl by step 6, page 13. FACTORY DEFAULTS - If, fr any reasn it is desirable t return all stred settings back t the factry default settings, press the Mde buttn.
