2.6 Installing the Batteries

nGently pull out the battery cover.

oInstall the batteries as shown. Observe the polarity.

pReinstall the battery cover. You will hear a clicking sound.

After the batteries are installed, the thermostat performs a sequence of tests for approximately 5 seconds.

Afterwards, the thermostat displays the measured temperature. It is normal that the displayed temperature be higher than the ambient temperature if you hold the thermostat in your hands. Once installed on the wall, the thermostat will display the ambient temperature. By default, the setpoint is 21°C (70°F) and the operating mode is set on manual.

The time and day settings flash to indicate that they must be set (see section 5.1).

2.7 Completing the Installation

nOnce the baseplate and the batteries are installed, mount the thermostat on the baseplate.

oSecure the thermostat using the locking screw and install the faceplate.

pApply power back to the system.

3.Basic Functions

3.1 System Operating Mode

AUTO

The fan operates only when heating or cooling is activated.

 

 

ON

The fan operates continuously.

 

 

3.3 Viewing and Setting the Temperature

The ambient temperature is normally displayed. To view the set-

point, press once on one of the buttons. The setpoint is dis- played for 5 seconds and is indicated by the symbol on the

display. During the setpoint display, press one of the buttons to change it.

3.4 Backlight

The display illuminates for 12 seconds when the backlight button or

either of the buttons is pressed.

3.5 Thermostat Control Mode

3.5.1 Manual

The setpoint must be set manually. To place the thermostat in this mode, press [ Mode ]. The house icon will disappear.

3.5.2 Automatic

The setpoint varies according to the programmed schedule. To place the thermostat in this mode, press [ Mode ]. The current period settings will be displayed. The four possible periods are:

Wake up

Leave for work

Return home

Sleep

To see the default schedule settings, see section 5.3.

3.5.3Unoccupied (TH148LE-P only)

To place the thermostat in unoccupied mode, see section 2.4. In this

mode, the icon is displayed and only the buttons work to allow a temporary bypass.

3.6 Temporary Bypass

3.6.1 Automatic Mode

If you modify the setpoint (using the buttons) when the thermo- stat is in automatic mode, the thermostat temporarily bypasses the current program. The new setpoint will be maintained for 2 hours, then the thermostat will return to the program currently running in automatic mode. The house icon flashes during the bypass.

3.6.2 Unoccupied Mode (TH148LE-P only)

If you modify the setpoint (using the buttons) when the thermo- stat is in unoccupied mode, the thermostat temporarily bypasses the setpoint of the unoccupied mode. The new setpoint will be main- tained for 2 hours, then the thermostat will return to the setpoint of

the unoccupied mode. The icon flashes during the bypass.

3.7 Filter Indicator

After 500 hours of operation, an icon appears to indi- cate that the filter needs replacement. Once the filter is replaced, press [ Filter ] for 3 seconds to remove the icon and reset the counter.

3.8 Battery Indicator

An icon appears when the batteries need replacement. This icon will flash for 120 days, then the thermostat will cut power to the heating/cooling unit. The icon dis- appears once the batteries are replaced and the ther- mostat reinstalled on its base.

Warning: Before removing the batteries, place the system switch on the thermostat to Off. Otherwise, the heating/cooling unit might still be running even after the batteries are removed.
