The mode indicates which system is used for temperature control. Use
the Heat / Cool button to select one of the following modes:
Controls the heating unit(s).
The heating unit is activated when the temperature falls below
the pre-defined Heat setpoints.
Controls the cooling unit(s).
The cooling unit is activated when the temperature exceeds the
pre-defined Cool setpoints.
Both units (HEAT and COOL) are OFF. The fan function is still
enabled but no setpoint changes are allowed.
Automatic changeover. Automatically alternates between HEAT
and COOL. See section 4.4 for details.
Setpoints represent the temperature that you wish to have during the
day, at night or while you are away. The Comfort and Economy set-
points are used with the Automatic mode (schedule, for programmable
models) while the Unoccupied setpoint can be used with the Unoccu-
pied mode (activated manually or remotely). This table displays the
default setpoints:
Comfort
Economy
Unoccupied
If your thermostat controls both HEATING and COOLING, the
setpoints must be configured for both applications.
The COOL setpoints cannot be lower than the Comfort Heat
setpoint. If this should happen, the TH144 will automatically set your
COOL setpoint 1° higher than your Comfort Heat setpoint.
To view the current setpoint, quickly press once on
one of these buttons
