1. Read these instructions carefully. Failure to follow the instructions can damage the product or cause a hazardous condition. 2. Check the ratings given in the instructions to make sure the product is suitable for your application. 3. Installer must be a trained, experienced service technician. 4. After completing installation, use these instructions to check out the product operation. Selecting Location Install the thermostat about 5 feet (1.5m), above the floor in an area with good air circulation at average temperature. See Fig.4. Do not install the thermostat where it can be affected by: ---Drafts or dead spots behind doors and in corners.

---Radiant heat from sun or appliances Concealed pipes and chimneys. ---Unheated or uncooled areas such as an outside wall behind the thermostat. Mounting Means: Mounts directly on the wall in the living space using mounting screws and anchors provided. Dimensions: 1. Lake Extra dimensions: see Fig. 1. 2. Lake Extra back case: see Fig. 2. 3. Lake Extra cover plate: see Fig. 3.

CAUTION Electrical hazard can cause electrical shock or equipment damage. Disconnect power before wiring. The thermostat can be mounted horizontally on the wall. 1. Position and level the wall plate (for appearance only). 2. Use a pencil to mark the mounting holes. 3. Remove the wall plate from the wall and if drywall, drill two holes in the wall as marked. For firmer material such as plaster, drill two holes. Gently tap anchors (provided) into the drilled holes until flush with the wall. 4. Position the wall plate over the holes, pulling wires through the wiring opening. See Fig.5. 5. Insert the mounting screws into the holes and tighten.

1. See Table 1 and Fig.6 for terminal designation descriptions. Insert wires in the terminal block under the loosened screw. See Fig.7. 2. Securely tighten each screw. 3. Push excess wire back into the hole. 4. Plug the hole with nonflammable insulation to prevent drafts from affecting the thermostat.

Terminal Designation Description RC (see Note 1) Power for cooling--connect to secondary side of cooling system transformer R (see Note 1) Power for heating--connect to secondary side of heating system transformer C (see Note 2) Common wire from secondary side of cooling system transformer Y Compressor contactor G Fan relay Y2 Second stage cooling O/B/W (see Note 3) Changeover valve for heat pump systems or Heat relay AUX/W2 Auxiliary heat relay for heat pump systems or Second stage heat relay E Emergency heat relay for heat pump systems L (see note 4) Equipment monitor for heat pump systems

RC and R. If used on a two-transformer system, remove metal jumper wire between RC and R. 2. Common wire is optional when thermostat is used with batteries. 3. If thermostat is configured for a heat pump system, configure changeover valve for cool or heat. 4. L terminal is an input port as system monitor. Fig.6.Terminal identifications for system.
