THERMOSTAT FEATURES

REMOVING OLD THERMOSTAT

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.

1. Remove OldThermostat : A standard heat/cool thermostat consists of three basic parts

• a. The cover, which may be either a snap-on or hinge type.
• b. The base, which is removed by loosening all captive screws.
• c. The switching subbase, which is removed by unscrewing the mounting screws that hold it on the wall or adaptor plate.
• Make a note here of the anticipator setting on the old thermostat for future reference and use in step 5.
• The heat anticipator pointer, if adjustable, will be set at one of a series of numbers representing the current rating of the primary control in your furnace. The number will be one of the following: .2, .4, .8, etc. or 0.2, 0.4, 0.8, etc.

REMOVING OLD THERMOSTAT

• 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 which 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 into a container which 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 location to send product containing mercury.

MOUNTING AND WIRING

WARNING

• 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 damage thermostat and could cause personal injury and/or property damage.
• Thermostat installation and all components of the system shall conform to Class II circuits per the NEC code.

A. Remove base from subbase : Loosen the screws on the base and remove.

B. Mount switching subbase : Use the screws provided to mount the subbase or wallplate to wall (see Fig. 1).
C. Attach wires to appropriate terminals :

• For two wire systems (Heat Only or Cool Only). Replace subbase with wallplate. If you have a two-wire Heat Only system, attach one wire to R and one to wire W. If you have a two-wire Cool Only system, attach one wire to R and one to wire to Y. Tighten any unused terminals securely. (see Fig. 5 and 6).
• If your system has more than two wires: Use the cross-reference chart to determine the correct wire connections. If you have a four-wire heat/cool system leave the factory installed jumper between RC and RH attached (see Fig 2.). If your system has five wires remove the factory-installed jumper between RC and RH (see Fig 3.).
• Electric heat or single-stage heat pump systems: These thermostats are configured from the factory to operate a heat/cool, fossil fuel (gas, oil, etc.) forced-air system. This is correct for any system that DOES NOT require the thermostat to energize the fan on a call for heat. If your system is an electric heat or heat pump system that REQUIRES the thermostat to turn on the fan on a call for heat, remove the yellow factory-installed jumper wire from the Y terminal and connect to the A terminal. This will allow the thermostat to energize the fan immediately on a call for heat. If you are unsure if the heating system requires the thermostat to control the fan, contact a qualified heating and air conditioning service person.
• For single-stage heat pump applications (no auxiliary heat), install a short jumper wire (not included) across terminals W and Y. If the system has a reversing valve connection energized in Cooling, attach it to O. If the system has a reversing valve connection energized in Heating, attach it to B (see Fig. 4). This thermostat will not provide multi-stage heating or cooling.
• D. Mount Thermostat Base : Gently push excess wire back into the wall opening and plug hole with a fire-resistant material, such as fiberglass insulation to prevent drafts from affecting thermostat operation. Mount the thermostat base to the subbase using the three captive screws on the thermostat base. (See Fig. 1) Tighten the screws securely. Proceed to Step #5.

CAUTION

• Take care when securing and routing wires so they do not short to adjacent terminals or rear of thermostat. Personal injury and/or property damage may occur.

SET HEAT ANTICIPATOR

• 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 the Millivolt Link.
• Snap-on Cover : Carefully align the cover with the base and snap the cover onto the base.

NEW THERMOSTAT OPERATION

• 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 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.
