White Rodgers 1F85CA-0471, 1F85-0471 instruction

INSTALLER/CONFIGURATION MENU

1)This control can be conﬁ gured for:

MS 2 – Multi-Stage System (no heat pump)

HP 1 – Heat Pump with one stage of compressor HP 2 – Heat Pump with two stage compressor or two compressor system, Gas or Electric backup

SS 1 – Single Stage System

2)GAS or Electric (ELE) fan operation. If the heating sys- tem requires the thermostat to energize the fan, select ELE. Select GAS if the heating system energizes the fan on a call for heat.

3)Select Cool Savings™ value – Selects the amount of adjustment for the Cool Savings™ feature in Cool mode with 1 (1°) being the least amount of adjustment and 6 (6°) being the most amount of adjustment. Default value is 0 which disables this feature. Selecting a value greater than 0 will display Cool Savings on the screen and enable the key for Cool Savings feature. Cool Sav- ings is an optional energy saving feature that can reduce your cooling costs. It is based on the principal that lower indoor humidity makes a slightly higher temperature feel more comfortable. Cool Savings operates during periods of high demand which normally occur on the hottest summer days when a cooling system may run for hours to reach the thermostat setting. Long cooling run times also lower the indoor humidity. Cool Savings, very slowly, adjusts the setpoint temperature to make the setpoint closer to the displayed room temperature, to a maximum of the number of degrees you select. Adjust- ing the setpoint temperature over a long cooling run time allows the system to reach your set temperature and turn off. The room temperature will actually be higher than the thermostat displays but the reduction in humidity will allow comfort at the slightly higher temperature.

To turn this feature on in the Cool mode press Cool Savings. The display will show “Save” next to the setpoint temperature. When Cool Savings is making ad- justments to the room temperature display “Save” will be ﬂ ashing and the displayed room temperature may vary within the adjustment range you selected.

If “Save” is not displayed and this feature is OFF, no change will occur when the cooling system is continu- ously running during periods of high demand.

4)Energy Management Recovery: (this step is skipped if conﬁ gured to be non-programmable). Energy Manage- ment Recovery (E) On enables the thermostat to start heating or cooling early to make the building temperature reach the program setpoint at the time you specify. Heat- ing will start 5 minutes early for every 1° of temperature required to reach setpoint.

Example: E On is selected and your heating is pro- grammed to 65° at night and 70° at 7 AM. If the build- ing temperature is 65°, the difference between 65° and 70° is 5°. Allowing 5 minutes per degree, the thermostat setpoint will change to 70° at 6:35 AM. Cooling allows

more time per degree, because it takes longer to reach set temperature.

5, 6 & 7) Cycle Rate Selection – The factory default setting for Heat and Cool modes, SS1, MS2, is medium cycle (ME). For Heat Pump, HP1, HP2, the default setting is medium (ME). For Emer (Aux) the default setting is fast

cycle (FA). To change cycle rate, press the			or
key.
Cycle rate differentials for different settings are:
	Fast	Medium Slow
MODE	FA	ME	SL
Heat (SS1, MS2)	0.4°F	0.6°F	1.7°F
Cool (SS1, MS2)	0.9°F	1.2°F	1.7°F
Heat Pump (HP1, HP2)	0.9°F	1.2°F	1.7°F
Emer (HP1, HP2)	0.6°F	-	1.7°F

8)Select Compressor Lockout CL OFF or ON – Select- ing CL ON will cause the thermostat to wait 5 minutes between cooling cycles. This is intended to help protect the compressor from short cycling. Some newer com- pressors already have a time delay built in and do not require this feature. Your compressor manufacturer can tell you if the lockout feature is already present in their system. When the thermostat compressor time delay oc- curs, it will ﬂ ash the setpoint for up to ﬁ ve minutes.

9)System Mode Conﬁguration – This thermostat is

conﬁ gured for Heat and Cool (SYSTEM switch with Cool, Off, Heat) default. It can also be conﬁ gured for Heat and Cool with Auto changeover (Heat, Auto, Cool, Off), Heat only with fan (Off, Heat), Heat only without fan, Auto only (Auto, Off), and Cool only (Cool, Off).

10)Select Backlight Display – The display backlight im- proves display contrast in low lighting conditions. When the “C” terminal is powered, selecting backlight CdL ON will keep the light on continuously. Select backlight OFF will turn the light on momentarily after any key is pressed. When the “C” terminal is not powered, the light will be on momentarily after any key is pressed no matter whether the backlight is selected ON or OFF.

11)Select Temperature Display Adjustment 4 LO to 4 HI

– Allows you to adjust the room temperature display up to 4° higher or lower. Your thermostat was accurately cali- brated at the factory, but you have the option to change the display temperature to match your previous thermo- stat. The current or adjusted room temperature will be displayed.

12)Select F° or C° Readout – Changes the display readout to Celsius or Fahrenheit as required.

13 & 14) Temperature Limit Range Heat or Cool – This selection sets the maximum HEAT (13) or minimum COOL (14) temperature for the setpoint range. Select the

limit temperature using the or keys. In the Run Schedule mode, the setpoint temperature will not adjust past the limit temperature selected. When the limit tem- perature is reached, trying to raise or lower the setpoint past the limit will cause “L” to be displayed in the times digits for about 6 seconds. This feature not available on earlier models.

15)Program Options: Not available on 1F83, conﬁ gured for 5/1/1 day or 5/2 day programming or non-programma- ble mode. The default setting is P3, indicating 5/1/1 day programming. The programs per week can be changed

to P2 or P0 by pressing the or keys. A selection of 0 Days for non-programmable will eliminate the need for EMR, and that step in the menu will be skipped.

16 & 17) Select Automatic Schedule – Not available on 1F83, with just one touch of the Auto Schedule button this feature allows you to program a desired comfort tem- perature into all the program periods along with a 6° set back for night periods of both Heat and Cool programs. Factory default is “On” for both. When Heat AS On and Cool AS On are activated while in Heat or Cool mode, select desired setpoint temperature and press Auto Schedule. This value will be copied into all the morning, day and evening program periods. The night program periods will have a 6°F set back.

18 & 19) Select Fast Second Stage ON or OFF – Heat pump or Multi-stage only, in the run mode, with the fast Heat feature enabled (FA Heat On), if the Heat setpoint temperature is manually raised by 3°F (2°C) or more

above the actual temperature using the second stage will energize immediately. With FA OFF, second stage will not energize until the setpoint temperature is 1°F or more above actual temperature for more than ten minutes. The Fast Cool feature (FA Cool) provides the same controls when the setpoint temperature is lowered.
