3. Carefully dress the wires so that any excess is pushed back into the wall cavity or junction box Ensure that the wires are flush to the plastic subbase The access hole should be sealed or stuffed to prevent drafts from the wall affecting the thermostat 7 Before the thermostat is reinstalled on the subbase install the optional clock timer indoor remote sensor and outdoor remote sensor if used Refer to the installation instructions supplied with each option Also check the position of the DIP switches on the back of the thermostat INSTALLATION INSTRUCTIONS CONT REPLACING THE THERMO STAT ON SUBBASE 1 Position the thermostat on the hinged tabs at the top of the subbase 2 Gently swing the thermostat down and press on the bottom center until it snaps into place THERMOSTAT COVER LOCK You may lock the cover down to prevent unauthorized access to the thermostat by adding the plastic lock included in the instal lation bag Insert the plastic lock piece into the bottom of the mounted base The ends of the lock piece fit snugly under the lock pins extending from the bot tom of the mounted base The tab in the middle of the lock piece extends down from the base To release the locking mecha nism press the lock piece up and into the base while gently prying open y ee ey te PSGSSOCbSBEGSO LEDER SBAG SS EG BDSABSA U NONN OAW
