• Countdown program

AUTOMATIC OPERATION

• After the reset phase, as soon as the date and time are set up, the device switches to
automatic operation.

• When in automatic operation, the device periodically measures the temperature in
the temperature zones it was programmed to control and performs zone temperature
control following the set up programs.

• The display reads the following information:

date and time
measured temperature (zone 1…4)
daily hourly graph (zone 1…4)
temperature measured by the external probe
temperature measurement unit
actuator status (zone 1…4)
presence of a wireless card

using keys

and . If key is pressed when on field 14 (see Figure 1), the
current zone name will appear (if it was entered; otherwise the reading “zona…” will
appear).

• To view the temperature measured by the external probe, press again

from field 14

(If the probe exists and was previously configured).

• To view the minimum and maximum temperature measured by the external probe
in field 5, press

again. To set these values to zero, hold the key down for at

least three seconds.

• To return to the main page, press key

again.

• To view the daily programming and the temperature in other zones, use arrow keys

and .

programming” section).

MANUAL OPERATION

• This function is enabled/disabled by pressing key

• When in manual operation, the display reads the
symbol and the programmable thermostat works as an
ordinary thermostat, using the setpoint read on field 14.

• The control setpoint can be changed using keys
and

. The setpoint may range from 2,0° to 35,0°.
The default setting is 18,0° for winter operation;
it is 23,0° for summer operation.

NOTE: the 4 zones can be switched to manual mode
with different individual setpoints.

EXTENSION PROGRAM

can be:

built-in (INT)
external (EXT)
remote via bus (BUS)

° the actuator associated to the zone, which can be:

relay (REL)
wireless (RF)
remote via bus (BUS)

° a description identifying the zone.

NOTE: to remote-program via bus, the Tx.Athena radio module must be
installed and the Athena programmable thermostat must be placed on the
wall-mounted base.

• If the probe selected for temperature control is an Athena.Temp probe, this is when
the probe is configured.

• If the actuator selected for the control zone is a remote actuator RX4-8A or RX1-

CONTROL BY TELEPHONE DIALLER

Athena has got an input for the connection to a clean contact to whom to connect for
example a telephone dialler to switch on or to switch off remotely the programmable
thermostat with their own telephone.
The contact can have one of these two positions:

- open = normal operation (according to the settings)

- closed = programmable thermostat in off mode.

When the symbol

appears on the main page, this means that the telephone contact

is closed (“OFF”).

NETWORK CONFIGURATION

• Athena programmable thermostats have only zone 1 configured by default, with the
built-in probe as temperature sensor and the device relay selected as actuator.

• To use wireless or bus remote actuators it is necessary to configure the network.

• To this purpose, select the remote probe and/or remote actuator for the desired zone
in the "configuration of individual control zones" menu. Then, before applying the
configuration procedure by pressing the [OK] key, switch the probe and/or remote
actuator to configuration mode (cfr. specific instructions) .

• After the [OK] key was pressed, if configuration is correct the device will read "OK".

ERROR MESSAGES

• During normal operation problems may prevent correct device functioning.

• For instance, if a probe (built-in, external or remote) is broken, the temperature field
for the zone in which the sensor belongs will read [--.-]. Temperature control in this
zone will then be inhibited and the corresponding actuator will be force-switched
“OFF”.

• When communication errors with bus peripherals occur, the display reads: “ERRORI
PERIFERICHE BUS Z…”

• To identify the problem it will be necessary to zone-test the device (cfr. note to the
paragraph "configuration of individual control zones").
