Heating/Cooling Thermostat and Subbase or Heating or Cooling Thermostat and Wallplate T8195A,B/Q682 OWNER'S MANUAL 69-0563-2 Welcome to the world of energy savings with your new Honeywell thermostat. The Honeywell name is your assurance of accurate control and reliable operation for years to come. This thermostat meets California Title 24 requirements--mandatory installation of automatic setback thermostats in new heating and cooling systems. During heating and cooling, this thermostat will automatically lower and raise the temperature in your home one or more times every 24 hours. This allows you to significantly lower your fuel costs, while awakening (or returning home) to a comfortable temperature. Read this manual to learn how to use your new thermostat. Recycling Notice M3375 This control contains mercury in a sealed tube. Do not place control in the trash at the end of its useful life. If this control is replacing a control that contains mercury in a sealed tube, do not place your old control in the trash. Contact your local waste management authority for instructions regarding recycling and the proper disposal of this control, or an old control containing mercury in a sealed tube. If you have questions, call Honeywell Inc. at 1-800-468-1502. 2 69-0563--2 Table Of Contents PAGE Features Of Your Thermostat ........................................................................................................... 4 Setting The Temperature ................................................................................................................. 7 Setting Subbase Switches ................................................................................................................ 8 Inserting Timer Backup Batteries ..................................................................................................... 9 Setting The Timer ........................................................................................................................... 10 Programming .................................................................................................................................. 11 Troubleshooting .............................................................................................................................. 14 Servicing The Thermostat .............................................................................................................. 21 Warranty ......................................................................................................................................... 23 3 69-0563--2 Features Of Your Thermostat 1 FLIP-UP COVER.

M8586 Fig. 1--Setting high and low temperature levers. 7 69-0563--2 Setting Subbase Switches (if applicable) The subbase system switch controls system operation as follows: HEAT--Heating system is controlled by the thermostat. Cooling system is Off. COOL--Cooling system is controlled by the thermostat. Heating system is Off. OFF-- Both the heating and cooling systems are Off. If the fan switch is at the AUTO position, the fan is also off. ON--In a cooling only application, only cooling operates. In a heating only application, only heating operates. The subbase fan switch controls fan operation as follows: ON--Fan operates continuously. AUTO--Fan operates with cooling equipment as contolled by the thermostat or with the heating equipment as controlled by the thermostat in heating and cooling. To switch positions, use thumb or index finger to slide lever to desired position. Switch lever must stop in the detent over desired function indicator mark for proper circuit operation. 8 69-0563--2 Inserting Timer Batteries (Optional) Power is supplied to the timer by the 24 Vac transformer. Two AAA alkaline backup batteries (not included) may be installed to supply power to the timer if power is interrupted due to power failure. Install the batteries in the thermostat as shown in Fig. 2. Once a year or when batteries are dead, replace with two new AAA alkaline batteries. We recommend Energizer® batteries. BATTERY LOCATION FOR (2) AAA BATTERIES; INSTALL WITH POSITIVE ENDS UP M8585 Fig. 2--Inserting timer backup batteries. 9 69-0563--2 Setting The Timer Lift thermostat flip-up cover and you will find the 24-hour program dial, slotted in 10-minute increments. Adjust the timer to the current time by carefully turning the knob clockwise Do not reverse the knob. When time is correctly set, the Time Indicator Arrow (See Fig. 3) will point to the correct time and corresponding daytime (light) or nighttime (dark) band of the program dial. EXAMPLE: For 11 p.m., time indicator arrow will point directly to dark band on dial. For 11 a.m., the arrow will point to light band on dial.

Do not reverse the knob or damage to the timer mechanism may occur. 10 69-0563--2 Programming You can program your thermostat to automatically lower and raise the temperature one or more times every 24 hours. pin storage area. You can set up to six temperature changes with the pins supplied. We recommend at least five hours for each energy savings period. 24-HOUR PROGRAM DIAL (GRAY AREA FOR NIGHT SETTINGS) Before Setting Your Program Lift thermostat flip-up cover and you'll find the 24-hour program dial. The slots on the program dial (Fig. 4) are for the program pins which can be inserted at ten-minute intervals. Three red and three blue program pins are included with your thermostat. The red pins start the high-temperature period; the blue pins start the low-temperature period. A heating program has been preprogrammed. A red pin is inserted at 6:00 a.m. for high temperature (comfort period); a blue pin is inserted at 10:00 p.m. for low temperature (energy saving period). Two additional sets of pins are located in the program 11 FLIP-UP COVER PROGRAM PINS THERMOSTAT COVER PROGRAM PIN SLOT PROGRAM INDEX WHEEL TIME INDICATOR ARROW PROGRAM PIN STORAGE M7348 Fig. 4--Program components. 69-0563--2 To change the pins or add a new energy savings period-- · To insert a pin, push it straight into the selected notch on the program dial until it's completely seated. · To remove a pin, press against program dial and pull the pin straight out. Do not attempt to change a pin if it is engaged with the program index wheel. · On heating-cooling systems, you must remove the program pins from the heating program to set new times for your cooling program.

After the red pin engages, the air conditioner will be off until room temperature rises to the energy savings setpoint. 13 69-0563--2 Troubleshooting Your Honeywell thermostat requires little or no attention. Most problems can generally be traced to the following: Problem No heat. Check -- system switch. May be in OFF or COOL position. 1 -- fuse or circuit breaker. -- furnace power switch. May be Off. -- pilot flame. May be out. -- R and W thermostat connections. Action Move system switch to HEAT position. If blown or tripped, replace fuse or reset breaker. Move switch to ON. Relight pilot flame per furnace manufacturers instructions. Turn Off power to furnace. Check for correct terminal hookups. Repair any frayed or broken wires. Firmly tighten all terminal screws. Turn On power. (continued) 14 69-0563--2 Troubleshooting (continued) Problem No heat (continued). Energy savings temperature program 12 hours off. Rooms do not warm up at programmed time. 2 Temperature change occurs at the wrong time. Room temperatures are not correct. Check -- other problem. -- program dial for proper day or night phase. -- timer program for heating system. May need more time to warm up rooms. -- programs pins for correct time locations. -- positions of thermostat setpoint levers. -- position of subbase system switch (heating-cooling model). Action Contact a qualified service technician for assistance. Turn timer ahead 12 hours. Move setting knob clockwise only. Move red pin one-half hour earlier on the program dial. Relocate pins to desired settings. Reset to desired temperatures. Move to desired operating position.
