REMOTE SENSOR (OPTION) RS1 – RS2 – RS+V The thermostat is designed to accept the electronic remote sensor (Uni-Line part #10-528) which will allow you to locate your thermostat in an area away from view. Indoor and outdoor sensors are available separately. CAUTION THIS DEVICE SHOULD BE INSTALLED BY A QUALIFIED TECHNICIAN WITH DUE REGARD FOR SAFETY, AS IMPROPER INSTALLATION COULD RESULT IN A HAZARDOUS CONDITION LOCATION To ensure proper operation, the thermostat should be mounted on an inside wall in a frequently occupied area of the building. In addition, its position must be at least 18" (46cm) from any outside wall, and approximately 5' (1.5m) above the floor in a location with freely circulating air of an average temperature. You should avoid the following locations: – behind doors or in corners where freely circulating air is unavailable; – where direct sunlight or radiant heat from appliances might affect control operation; – on an outside wall; – adjacent to, or in line with, conditioned air discharge grilles, stairwells, or outside doors; – where its operation may be affected by steam or water pipes or warm air stacks in an adjacent partition space, or by an area behind the thermostat which is not climate controlled; – where its operation will be affected by the supply air of an adjacent climate control HVAC device; and – near sources of electrical interference such as arcing relay contacts. CLOCK TERMINALS (OPTION) CLK1 – CLK2 INSTALLATION INSTRUCTIONS (cont) REPLACING THE THERMOSTAT ON SUBBASE THERMISTOR MOUNTING INSTRUCTIONS When placing the front cover on the thermostat ensure the thermistor is not bent or misaligned. Ensure that the thermistor does not touch the thermostat case. The thermistor should be placed horizontal to the wall. Ensure the thermistor is not pushed upward into the case. The thermistor should be aligned so it is visible between the ribs on the bottom of the 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 installation 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 bottom of the mounted base. The tab in the middle of the lock piece extends down from the base. To release the locking mechanism, press the lock piece up and into the base while gently prying open. Your thermostat is equipped with a dry contact closure input. By connecting to any relay-based controller or clock timer, the thermostat can be alternated between the day and night (setback) temperature setpoints automatically. Upon initial power up of the thermostat or after a power failure, the thermostat will check the clock terminals and apply the day (open contact) or night (closed contact) temperature setpoints accordingly. Outside rear view with backplate closed ECONOMY / COMFORT In the economy mode (switch #5 OFF) your thermostat will not allow the equipment to be forced on with a change to the temperature setpoint. In the comfort mode, the equipment will turn on immediately with a change to the temperature setpoint. WIRING DIAGRAM CAUTION TEMPERATURE ACCURACY Full temperature accuracy will be realized only after the thermostat has been installed and powered for at least one (1) hour. ADD-ON HEAT PUMPS Your DSL thermostat is equipped to enhance the performance of an add-on heat pump. Your thermostat, in most applications, will perform the function of a fossil fuel kit. To select ADD-ON, place switch #1 to the ON position. The thermostat will turn the compressor off with a call for auxiliary heat. When the switch is set to NORMAL, the thermostat will allow the compressor and the auxiliary heat to be on at the same time. POWER FAILURES Your thermostat employs the latest in solid state electronic technology. One of the unique features of your thermostat is that no battery is required to maintain your selected setpoints in the event of a power loss as the memory is unaffected by power failures of any duration. When power is restored, the thermostat will continue operating as if the power had never been off. REMOVING THE THERMOSTAT FROM THE SUBBASE 1. Insert a flat blade screwdriver or coin 1/8" into the slot located in the bottom center of the thermostat case and twist 1/4 turn. When you feel or hear a click, grasp the case from the bottom two corners and separate from the subbase. Some models require more force than others when separating due to the number of terminals on 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 control wires protruding from the wall and, using the subbase as a template, mark the location of the two mounting holes (exact vertical mounting is necessary only for appearance). 5. Use the supplied anchors and screws for mounting on drywall or plaster; drill two 3/16" (5mm) diameter holes at the marked locations; use a hammer to tap the nylon anchors in flush to the wall surface and fasten subbase 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 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 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. Power is supplied through the thermostat to the remote devices. DO NOT connect any other 24V source to the remote devices. 300-202 (for Release 3) the thermostat.
