Safety

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 the 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 hazards.
Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will burn out the thermostat and could cause personal injury and/or property damage.
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.

Installation

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, sunlight, 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 ductwork.

Mounting / Installation

Follow these steps to mount the 202 Control to the wall.

1. Turn OFF all power to heating and cooling equipment.
2. If an existing thermostat is being replaced:
   1. Record color and terminal marking of each wire.
   2. Disconnect the wires from the existing thermostat being careful not to allow them to fall back into the wall.
   3. Remove the existing thermostat from the wall.
3. Pull the thermostat body off the thermostat base. Forcing or prying on the thermostat will cause damage to the unit.
4. Move base over the hole in wall and mark mounting hole locations on wall using base as a template. (See Fig. 1)
5. Move base out of the way. Drill mounting holes. If you are using existing mounting holes pull thermostat wire bundle through the hole in the thermostat base. Mount sub-base to wall. Leveling is for appearance only and will not affect thermostat operation.
6. Connect wires to the terminal block on the base using appropriate wiring diagram.
7. Push excess wire into wall and plug the 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.

Battery Location

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.

Troubleshooting

SYMPTOM	POSSIBLE CAUSE	CORRECTIVE ACTION
No Heat/ No Cool/ No Fan (common problem)	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.) 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
No Heat	1.) System Switch not set to Heat 2.) Loose connection to thermostat or system 3.) Heating System requires service or thermostat requires replacement	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.
No Cool	1.) System Switch not set to Cool 2.) Loose connection to thermostat or system 3.) Cooling System requires service or thermostat requires replacement	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)
Heat, Cool or Fan Runs Constantly	Possible short in wiring, thermostat, heat, cool or fan system	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)	The location of the thermostat and/or the size of the Heating System may be influencing the cycle rate	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.
“Call for Service” icon appears on displayed	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	1.) See corrective action for “No Heat” 2.) See corrective action for “No Cool” 3.) Replace thermostat 4.) Make sure keypad lockout is not turned on (denoted by the icon)
