OPERATING INSTRUCTIONS

General description

The time-thermostat manages ambient temperature control and control of the boilers, zone valves, conditioning units, fan-coils, etc. through a relay output.

Activating the combined output modules makes it possible to control: boilers, zone valves, air conditioners, fan-coils, etc.

The timer-thermostat is provided with a display, 3 control buttons that are always accessible and 7 control buttons accessible when the hatch is open.

OPERATING INSTRUCTIONS

Operating modes

The timer-thermostat offers 3 different operating modes::

• AUTOMATIC
• MANUAL
• OFF/ANTIFREEZE/HIGH TEMPERATURE PROTECTION

Key is used to switch from one mode to another.

1 2 3 4 5 6 7 16:28 T-22.2°C AUTO 0 1 2 3 4 5 6 7 12 21 24

In automatic operation the timer-thermostat uses a program that can be different for every day of the week.

The text AUTO, the ambient temperature measured and the symbol of the set point relative to the current quarter of an hour appear on the display.

In the hourly profile the column relative to the current hour blinks with the representation of the active set point.

1 2 3 4 5 6 7 16:28 22.2 °C MAN

In manual operation the timer-thermostat permanently uses a temperature set point that can be freely set.

The text MAN and the ambient temperature measured appear on the display.

1 2 3 4 5 6 7 16:29 22.4 °C OFF

The antifreeze/high temperature protection operations are active in heating and air conditioning mode respectively.

In these two cases the time-thermostat uses the antifreeze/high temperature protection temperature set point that has been set.

The message "OFF" and the measured ambient temperature are displayed on the VDU.

To activate manual operating mode, press key , until the text MAN appears on the display. The temperature set point appears for about two seconds.

Use keys to set the required set point value, press key, or wait 5 seconds to confirm the setting.

Remote control

The time-thermostat can be connected to the GSM GW 90 821 remote control unit by a serial connection.

The SMS commands can thus be used to:

• set the type of operation (air conditioning/heating)
• set the operating mode (manual/automatic/off)
• set the operating set point (in MAN mode only)
• request the current status

Every SMS command sent to the device has a corresponding confirmation SMS (with predefined text that cannot be configured);

the status request message gives a reply that includes the following information:

• current operating mode (off/auto/man)
• set point temperature currently set
• ambient temperature measured
• relay output status (ON/OFF)

- current operating type (heating/air conditioning)

The following symbol is displayed on the VDU whenever the operating type or mode are modified from the remote control unit.

OPERATING INSTRUCTIONS

Low batteries indication

1 2 3 4 5 6 7 12:08 20.7°C MIN

When the batteries charge is low, the symbol on the display starts to blink. Operation of the timer-thermostat is guaranteed in any case. In this case, the batteries must be replaced as soon as possible.

Timer-thermostat operation is no longer guaranteed when symbol is fixed on, in this case the last operation guaranteed is automatic deactivation of the heating/air conditioning.

The available time for replacing the batteries is about 2 minutes, after which only the clock/calendar setting will be lost: all the other settings are kept in non-volatile memory.

Reset and restore the preset values

Pressing keys, simultaneously performs a complete reset of the timer-thermostat.

N.B.: all parameters set and personalized programs will be cancelled.

When the timer-thermostat is switched on again, it uses the parameters and programs preset in the factory. The timer-thermostat goes into heating in AUTO mode. The Party and Holiday functions are not active.

OPERATING INSTRUCTIONS

Preset programs

The timer-thermostat has 2 preset programs, one for heating and one for air conditioning.
