sensor is not functioning, when you exit the menu, CHECK STAT SYSTEM will be displayed. To correct this, check for proper remote sensor installation and wiring. If necessary, return to the menu and be sure that the remote sensor items are set correctly.

The temperature at each remote sensor can be displayed by pressing the light button twice within one second with the thermostat in program run or hold mode. Temperatures at the outdoor and indoor remote sensors will be displayed with subsequent presses of the light button in the following order (if connected): outdoor sensor, sensor L, A, b, C.

(Installer table step 17). If you wish to sense indoor temperature using ONLY the remote sensor(s), use this menu item to disable the temperature sensor in the thermostat

After using the Installer menu to properly configure the thermostat for your system,

press PROGRAM RUN .

OUTDOOR TEMPERATURE SENSE.

This thermostat can also display outdoor temperature, if you install an outdoor remote sensor with an outdoor temperature sensor probe (F145-1378). Refer to the remote sensor installation instructions for proper installation and wiring. Refer to the Operat- ing Instructions to enable this feature and display outdoor temperature on the thermo- stat.

OPTIONAL ACTIVATE RUN PRG BY TELEPHONE

With the optional X-10 Telephone Responder (Model TR551, Radio Shack catalog RSU# 10037778) and Universal Low Voltage Module (UM506, Radio Shack catalog RSU# 10037752) installed, you can make a telephone call to run your program if the thermostat has been set to Hold or Vacation Hold. Figure 3 shows typical wiring connections for installing the X-10 equip- ment. The switch on the Universal Low Voltage module must be set to the “Momen- tary” position.

This option must be enabled on the User menu (see Operating Instructions).

(designated as the L sensor).

When operating with remote sensor(s), the thermostat will calculate an average of the sensed temperatures in all enabled sensor locations (A, b, C and/or L), then display the average temperature as the room tempera- ture. During programming, you can also assign each enabled sensor different priorities during different program periods. This allows the system to maintain a comfortable environment by giving higher priority to occupied locations. At the same time, efficient system operation is enhanced by giving lower priority to unoccupied locations. For detailed instructions on this feature, see the Operating Instructions.

1.Press PROGRAM RUN .

2.Press SYSTEM until COOL is displayed.

3.Press to adjust thermostat setting below room temperature. The fan should

come on (after the fan-on delay time, if any), followed by cold air circulation.

4.Press to adjust temperature setting above room temperature. The cooling system

should stop operating, and the fan should stop running (after the fan-off delay time, if any).

MULTI-STAGE/HEAT PUMP AUXILIARY OPERATION TEST

Follow these steps to energize all stages of heat or cool to permit system checks during installation.

HEAT: Press to raise temperature setting to 99°F, then hold for five seconds. The second and third stage heat relays will energize immediately for test purposes. The LED indicator will glow green for first stage and yellow for second stage.

COOL: Press to lower temperature setting to 45°F, then hold for five seconds. The second stage cool relay will energize immediately for test purposes. The LED indicator will glow green for first stage and yellow for second stage.

EMERGENCY (heat pump only): Press SYSTEM to select EMER mode. The LED indicator will glow red for emergency mode. A flashing light indicates a malfunction in the system.
