FUNCTIONS
Clock
As an alternative to displaying the current temperature the time can be displayed instead
(hours and minutes). Simply press the display temp/time button
.
User Profile
Two different user profiles are available that feature three different temperature levels
(COMFORT, ECO and NIGHT). These profiles can be used in both “HEATING” and “COOLING”
modes.
Heating, Cooling and System Bypass
The TA450 can operate in either “HEATING” or “COOLING” mode with the additional option
of frost protection without temperature control. Both modes offer the selection of three
different temperature levels.
Three levels of temperature control
In order to obtain the maximum of comfort in either heating or cooling mode the TA450
offers the possibility of selecting, in a simple and intuitive way, three different temperature
levels (COMFORT, ECO and NIGHT) which together allow for temperature programmability
over the range +3°C to +35°C. The TA450 is pre-programmed with the following tempera-
ture values.
In heating mode
In cooling mode
COMFORT 20 °C
COMFORT 24 °C
ECO 18 °C
ECO 26 °C
NIGHT 16 °C
NIGHT 28 °C
If these values correspond to your needs then the TA450 will not require further program-
ming.
Accumulated System Operating Time
The TA450 features an hour-counter (up to 9,999), which records the system’s overall number
of operating hours.
Remote Control
By means of a telephone dialler or similar appropriate telephone controlling device the
TA450 can be activated remotely thus guaranteeing a warm welcome home. Remote
control activation is made evident by the presence of the dedicated icon on the display.
Note. Closing the isolated contact will activate the thermostat at the programmed tempera-
ture; opening it will turn the thermostat OFF.
