Insert a flat blade screwdriver or coin 1/8" into the slot located in thebottom center of the thermostat case and twist 1/4 turn. When you feelor hear a click, grasp the case from the bottom two corners and sepa-rate from the subbase. 2. Swing the thermostat out from the bottom.3. Lift the thermostat up and off the subbase.4. Place the rectangular opening in the subbase over the equipment con-trol wires protruding from the wall and, using the subbase as a tem-plate, mark the location of the two mounting holes (exact verticalmounting is necessary only for appearance).5. Use the supplied anchors and screws for mounting on drywall or plas-ter; drill two 3/16" (5mm) diameter holes at the marked locations; use ahammer to tap the nylon anchors in flush to the wall surface and fastensubbase using the supplied screws. (Do not overtighten!)6. Connect the wires from your system to the thermostat terminals.Carefully dress the wires so that any excess is pushed back into thewall cavity or junction box. Ensure that the wires are flush to the plasticsubbase. The access hole should be sealed or stuffed to prevent draftsfrom affecting the thermostat.Replacing the Thermostat on Subbase1. Position the thermostat on the hingedtabs at the top of the subbase.2. Gently swing the thermostat downand press on the bottom center untilit snaps into place.Thermostat Cover LockInsert the plastic lock piece into the bot-tom of the mounted base. The ends ofthe lock piece fit snugly under the lockpins extending from the bottom of themounted base. The tab in the middle ofthe lock piece extends down from thebase.To release the locking mechanism,press the lock piece up and into thebase while gently prying open.Thermistor Mounting InstructionsWhen placing the front cover on thethermostat ensure the thermistor is notbent or misaligned.Ensure that the thermistor does nottouch the thermostat case. The thermis-tor should be placed horizontal to thewall. Ensure the thermistor is notpushed upward into the case.The thermistor should be aligned so it isvisible between the ribs on the bottomof the subbase.DIP SWITCH OPTIONS AND FUNCTIONSPositioning the DIP switches in either the ON or OFF position enablesyou to choose between two different options.
