Assemble tools required: power drill, flat blade screwdriver, wire cutter/stripper, level. Failure to follow and read all instructions carefully before installing or operating this control could cause personal injury and/or property damage.
CAUTION
To prevent electrical shock and/or equipment damage, disconnect electrical power to the system at the main fuse or circuit breaker until installation is complete.
Before removing wires from old thermostat’s switching subbase, label each wire with the terminal designation it was removed from.
If no heat anticipator/indication is showing, do not be concerned; move on to the next step.
ATTENTION!
This product does not contain mercury. However, this product may replace a unit that contains mercury.
Do not open mercury cells. If a cell becomes damaged, do not touch any spilled mercury. Wearing non-absorbent gloves, take up the spilled mercury and place it into a container that can be sealed. If a cell becomes damaged, the unit should be discarded.
Mercury must not be discarded in household trash. When the unit this product is replacing is to be discarded, place in a suitable container. Refer to www.white-Rodgers.com for a location to send products containing mercury.
WARNING
CAUTION
Take care when securing and routing wires so they do not short to adjacent terminals or rear of the thermostat. Personal injury and/or property damage may occur.
Set the anticipator to match the setting of your old thermostat you noted in Step 3, or, the anticipator should be set to match the current rating stamped on your main heating control. The heat anticipator is adjustable from 0.15 to 1.2 amps. Adjust the anticipator by rotating the contact arm (see fig. 5). The anticipator setting is indicated by the numbers on the base that the pointer points to. If you are unsure where to set the anticipator contact the heater manufacturer for a recommended setting. Move the pointer counterclockwise to lengthen heating system cycles; move clockwise to shorten heating cycles.
Adjustments should not be greater than 1/2 marking at a time.
For millivolt operation, rotate the contact arm to Millivolt Link.
Snap-on Cover: Carefully align the cover with the base and snap the cover onto the base.
The thermostat on Subbase. After power is turned on, use the system switch to select either heating or cooling, or to turn the heating/cooling system off. Use the fan switch to control fan operation. When the fan switch is in the AUTO position, the fan will cycle with the heating or cooling system (the fan will not run if the system switch is in the OFF position and the fan switch is in the AUTO position). When the fan switch is in the ON position, the fan will run continuously, regardless of the system switch position (even if the system switch is set to OFF, the fan will run if the fan switch is in the ON position).
Thermostat on wallplate. For heat only move the temperature lever to the highest temperature. For cool only move the temperature lever to the lowest temperature.
ELECTRICAL DATA
Anticipator Rating:
THERMAL DATA:
Symptom | Possible Cause | Corrective Action |
No Heat/No Cool/No Fan (common problems) | 1. Blown fuse or tripped circuit breaker. 2. Furnace power switch to OFF. 3. Furnace blower compartment door or panel lose or not properly installed. | Replace the fuse or reset the breaker. Turn the switch to ON. Replace the door panel in the proper position to engage the safety interlock or door switch. |
No Heat | 1. Pilot light not lit. 2. Broken or melted anticipator wire. 3. Loose connection to thermostat or system. 4. Thermostat or heating system requires replacement or service. 5. System Switch not set to Heat. | Re-light pilot. Excessive current or dead short in the system. Have a qualified service person check the system before replacing the thermostat. Verify thermostat and system wires are securely attached. Your furnace manufacturer or service person can describe how to test the heating system to verify it is operating correctly. If the heating system is capable of operation and the no heat condition persists, replace the thermostat. Set System Switch to Heat and raise temp above room temp. |
Intermittent Heat | 1. Furnace Lock-Out Condition | Many furnaces have safety devices that shut the system down when a lock-out condition occurs. If the heat works intermittently contact the furnace manufacturer or local service person for assistance. |
No Cool | 1. Loose connection to thermostat or system. 2. Thermostat or cooling system requires replacement or service. 3. System Switch is not set to Cool. | Verify thermostat and system wires are securely attached. Your cooling system manufacturer or service person can describe how to test the cooling system to verify it is operating correctly. If the cooling system is capable of operation and the no cooling condition persists, replace the thermostat. Set the System Switch to Cool and lower temp below room temp. |
Heat, Cool or Fan Runs Constantly. | 1. Possible short in the wiring. 2. Possible short in thermostat. 3. Possible short in heat/cool/fan system. | Check each wire connection to the thermostat to verify it is neatly looped under the terminals. No extra wire should stick out from under the terminals. |
Furnace Cycles Too Fast or Too Slow Narrow or wide temperature swing | See Step 5, Adjusting the Anticipator. | The anticipation setting is the only adjustment that effects the heating cycle rate. If an acceptable cycle rate is not achieved using the anticipator contact a local service person for additional suggestions. The location of the thermostat, the size of the Heat/Cool System, and the current draw can influence the cycle rate. |
Cooling Cycles Too Fast or Too Slow (narrow or wide temperature swing) | 1. Poor thermostat location for sensing room temperature. 2. Cooling system over or undersized. 3. Excessive Current draw influencing thermostat. | The cycle rate for cooling can not be adjusted. The location of the thermostat, the size of the Cool system and the current draw can influence the cycle rate. Contact a local service person for suggestions. |
Thermostat Setting and Thermostat Thermometer Disagree | 1. Thermostat thermometer setting requires adjustment. 2. Thermostat setting lever requires calibration. | The thermometer can be adjusted by using a standard slotted screwdriver. Turn the thermometer pointer screw located inside the front cover to change the setting. For calibrating the setting lever contact a local heating and cooling service person. |
Adjusting Thermometer | 1. Thermostat thermometer disagrees with other room thermometers. | The thermometer on the thermostat is accurately calibrated at our factory but you can adjust it by using a standard slotted screwdriver. Turn the thermometer pointer screw located inside the front cover to change the setting. |
