WARNING FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE. This information is intended for use by individuals possessing adequate backgrounds of electrical, mechanical, HVAC and experience. Any attempt to repair a HVAC system may result in personal injury and/or property damage. The manufacturer or seller cannot be responsible for the interpretation of this information, nor can it assume any liability in connection with its use. LIVE ELECTRICAL COMPONENTS! During installation, testing, servicing, and troubleshooting of this product, it may be necessary to work with live electrical components. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury. Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard. Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will burn out thermostat and could cause personal injury and/or property damage. 2 L! CAUTION To prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until installation is complete. To prevent compressor and/or property damage, if the outdoor temperature is below 55°F, DO NOT operate the cooling system. Do not allow the compressor to run unless the compressor oil heaters have been operational for six hours and the system has not been operational for at least five minutes. ATTENTION: MERCURY NOTICE This product does not contain mercury. However, this product may replace a product that contains mercury. Mercury and products containing mercury must not be discarded in household trash. Do not touch any spilled mercury. Wearing nonabsorbent gloves, clean up any spilled mercury and place in a sealed container. For proper disposal of a product containing mercury or a sealed container of spilled mercury, place it in a suitable shipping container.

General Information 3.1 Overview The 202 is a programmable push button single stage thermostat with a 3.5'' backlit display. The 202 features a scheduling mode that can operate a 7-day program, 5-1-1 program or operate in a non-programmable mode. 3.2 Contents -- 1-Thermostat -- 1-Sub-base -- 2-Phillips slotted head mounting screws -- 2-Nylon Drywall Anchors -- 1-Installation Guide / User Guide 3.3 Accessories Wall Cover Plate (BAYCOVR200A) 4. Installation 4.1 Location The 202 is designed for installation in climate controlled living spaces. Place the unit in a central location with good circulation. For proper temperature sensing, avoid exposing the 202 to heat radiated from lamps, sun light, fireplaces or any other radiant heat source. Avoid locations close to windows, behind doors or alcoves with poor air circulation, adjoining outside walls, or doors that lead to the outside. Select a location that prevents the 202 from being directly exposed to air currents from supply registers or ceiling fans. Mount the Control on a section of interior wall that does not contain hot or cold water pipes or duct work. Pub.

Push excess wire into wall and plug hole with a fire resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation. 8. Two "AA" alkaline batteries are included in the thermostat at the factory with a battery tag to prevent power drainage 9. Remove the battery tag to engage the batteries 4.3 Battery Location Figure 2. Battery Location Premium AA alkaline batteries are required when C-wire is not available. When C-wire is available, the batteries provide a back-up source of power (this will maintain the clock in the event of a power outage). IMPORTANT: · Leveling Thermostat Leveling is for appearance only and · will not affect thermostat operation. · Gas/Electric Switch If the system is a heat pump or electric furnace, the GAS/ELEC Switch must be set to Electric. If your system is a gas or oil furnace, the switch must be set to Gas. Do not exceed the specification ratings. All wiring must conform to local and national electrical codes and ordinances. This control is a precision instrument, and should be handled carefully. Rough handling or distorting components could cause the control to malfunction RC/RH Jumper Wire This thermostat electrically connects the RC and RH terminals so a jumper wire is not required. If the application provides a separate wire for RC and RH, clip the RC/RH jumper. This will isolate both terminals so they can be independently used. O/B Terminal Switch The O/B switch on this thermostat is factory set to the O position. This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in Cool. If the heat pump being installed requires a B terminal, to energize the changeover relay in Heat, the O/B switch must be moved to the B position. To enable single stage heat pump operation a jumper must be field installed between Y and W. The 202 does not support auxiliary heat. 4.4 Battery Replacement To replace batteries, set system to OFF, remove thermostat from wall and install the batteries in the rear along the top of the thermostat (see Figure 1). For best results, use a premium brand "AA" alkaline battery such as Duracell® or Energizer®. If the home is going to be unoccupied for an extended period (over 3 months) and " " is displayed the batteries should be replaced before leaving. 4 Pub.

Troubleshooting SYMPTOM POSSIBLE CAUSE CORRECTIVE ACTION No Heat/ No Cool/ No Fan (common problem) No Heat No Cool Heat, Cool or Fan Runs Constantly 1.) Blown fuse or tripped circuit breaker 2.) Furnace power switch to OFF 3.) Furnace blower compartment door panel loose or not properly installed 4.) Loose connection to thermostat or system 1.) System Switch not set to Heat 2.) Loose connection to thermostat or system 3.) Heating System requires service or thermostat requires replacement 1.) System Switch not set to Cool 2.) Loose connection to thermostat or system 3.) Cooling System requires service or thermostat requires replacement Possible short in wiring, thermostat, heat, cool or fan system 1.) Replace fuse or reset breaker 2.) Turn switch to ON 3.) Replace door panel in proper position to engage safety interlock or door switch 4.) Tighten Connections Verify thermostat and system wires are securely attached. Diagnostic: Set System Switch to Heat and raise the setpoint above room temperature. Within five minutes the thermostat should make a soft click sound and "Heat On" should appear on display. This sound indicates the thermostat is operating properly. If the thermostat does not click, try the reset operation listed below. If the thermostat does not click after being reset, contact your heating and cooling service person or place of purchase for a replacement. If the thermostat clicks, contact the furnace manufacturer or a service person to verify the heating system is operating correctly. Verify thermostat and system wires are securely attached. Diagnostic: Set System Switch to Cool and lower setpoint below room temperature. Same procedures as diagnostic for "No Heat" condition except set the thermostat to Cool and lower the setpoint below the room temperature. There may be up to a five minute delay before the thermostat clicks in Cooling if the compressor lock-out option is selected in the installer menu. (see INSTALLER MENU, item 50) Check each wire connection to verify they are not shorted or touching other wires. Try resetting the thermostat. If the condition persists contact your HVAC service person. Thermostat Display & Thermometer Disagree Thermostat display requires adjustment Display can be adjusted +/-5°. See User Menu item 04 Furnace (Air Conditioner) Cycles Too Fast or Slow (narrow or wide temperature swing) "Call for Service" icon appears on displayed The location of the thermostat and/or the size of the Heating System may be influencing the cycle rate 1.) Heating system is not able to heat the space to within 10 degrees of the setpoint within 2 hours 2.) Cooling system is not able to cool the space to within 10 degrees of the setpoint within 2 hours 3.) If "--" is displayed for the Room Temperature, a replacement thermostat is needed 4.) None of the buttons operate on the thermostat Digital thermostats provide precise control and cycle faster than older mechanical models. The system turns on and off more frequently but runs for a shorter time. If you would like to increase cycle time, choose SLO for slow cycle in the Installer menu. (Reference menu items 30 & 35) If an acceptable cycle rate is not achieved, contact your HVAC service person. 1.) See corrective action for "No Heat" 2.) See corrective action for "No Cool" 3.) Replace thermostat 4.)
