the same 4 programs as shown in the table or each day can have a different set of 4 programs. (4 for winter and 4 for summer). You can generate significant savings with a programmable thermostat. The idea is to reduce usage when you don’t need it—when you’re not home or at night while everyone’s asleep. For example, during the heating season you can program lower temperatures during the day while you’re at work. Then program a comfortable temperature just before you get home, so you walk into a warm house.
Start Up 5 Keyboard Lock Feature Your thermostat is provided with an optional electronic keyboard lock. You may use this feature to prevent tampering with the programs. The keyboard can be made active by using the key provided with your thermostat. If you elect to use this feature, remove the cover from the thermostat and look for the switch shown below on the printed circuit board near the key hole. Be careful not to disconnect any wires. Then slide the keyboard switch to “lock” mode.

Here are two ways to do this: “temporary” and “constant.” Temporary Manual Override (OVERRIDE UNTIL NEXT PROGRAM) In the following example, we are raising the temperature from a program setting of 70°F to a temporary setting of 72°F until the time of the next program change.

Emergency Operation: In this operation the compressor will not operate. Only auxiliary heat will control the room temperature as per your heating program. For example, you might select this mode to bypass your heat pump, if you suspect it is not operating properly. 1.

Read This First Before Installing Thermostat IMPORTANT Read the entire installation section of this Installation Manual thoroughly before you begin to install or operate your thermostat. • Remove the mylar label from the display window. 1 19 TEMPERATURE RANGE This thermostat can be programmed between 40°F and 90°F. However, it will display room temperatures from 32°F to 99°F. 5 POWER FAILURE The thermostat is fully battery operated and does not require power from the control circuit.
Remove Old Thermostat 20 ■ Turn off the power to the furnace at the main power panel or at the furnace. This thermostat comes with two #8 slotted screws and two wall anchors for mounting. To install your unit, you should have the following tools and materials. ■ Slotted screwdriver ■ Hammer ■ Remove existing thermostat cover and thermostat. Some thermostats will have screws or other locking devices that must first be removed. Once wall mounting plate is exposed, look for wires.
Label Wires (cont.) 21 The number of wires in the system can be as few as four (for single stage heat pump systems), as many as eight, or any number in between for multistage heat pump systems. If you follow the labeling procedures correctly, you don't have to be concerned about how many wires there are. ■ After labeling wires, disconnect them from the existing thermostat terminals. ■ Remove existing wallplate. To make sure wires do not fall back into wall opening, tape them to the wall.
Connect Wires and Mount Thermostat Cover to Wall Plate ■ Match and connect the labeled wires to the appropriate coded terminal connector on the mounting plate. (See Figure 3A.) Ignore any wires which may be present, but which were not connected to the old thermostat. ■ Push excess wire back into hole to prevent interference with mounting of the thermostat cover. ■ Insert three AA size batteries into the wallplate as shown in Figure 4, observing the polarity marked on the unit.
