When the REM input is connected to a central
system or a telephone controller and a signal is
received through this input, the TH144 will switch
to the unoccupied setpoint.
• The yellow LED on top of the display turns on
when the unoccupied mode is activated.
• The
icon is also displayed.
• For details on how to operate your telephone
controller (CT240/CT241), see your manual.
• When this mode is activated remotely it can only be deactivated
remotely. Although, it can be bypassed for a 2-hour period (see 4.2).

When the AUTO mode (automatic changeover) is
selected, the thermostat analyzes the system’s
requirements and automatically alternates
between HEAT and COOL mode to provide occu-
pant comfort.
There are two ways to use the automatic change-
over mode:

When you set the temperature using the
arrow buttons, the TH144
uses this unique temperature setpoint for temperature control.
The thermostat automatically switches to HEAT mode when the ambi-
ent temperature drops under the temperature setpoint whereas the
COOL mode is activated when the temperature rises above the tem-
perature setpoint.
In order to switch modes, the ambient temperature must be maintained
over or under the control band for more than 12 minutes.

When a predefined setpoint button is selected, the TH144 uses the cor-
responding COOL and HEAT setpoint temperatures for temperature
control.
The thermostat automatically switches to COOL mode when the ambi-
ent temperature rises above the COOL setpoint whereas the HEAT
mode is activated when the ambient temperature drops below the
HEAT setpoint.
In order to switch modes, the ambient temperature must be maintained
over or under the setpoint control band for more than 12 minutes.
