1. Timer-Thermostat 02910

Wall-mounting, battery-powered timer-thermostat with interface with capacitive keys and equipped with
user-friendly functions to facilitate energy saving.
Designed to control heating and air-conditioning via C, NC, NO relay output.
Equipped with multi-function input for remote control (reduction, activation, summer/winter switching).
Can be connected, via circuit board 02915, to the energy probe 02960 (not supplied) for viewing consumption/
generation of electricity and corresponding historical data.
If the device is used in combination with the energy probe 02960 a built-in buzzer is available.

2. Field of application

The appliance is designed to control room temperature by acting on the control circuit of the burner or circu­lation pump (heating) or on the control circuit of the air conditioner
(air conditioning), ensuring an ideal temperature.
The graphical user interface, thanks to special views, facilitates system management helping the user to oper­ate while maintaining a state of energy saving.
Consultation of the energy consumption (or generation) carried out by connecting to the energy probe 02960,
lets you monitor up to 3 separate phases (with common neutral), for a maximum of 10kW per phase. The
device will not activate/deactivate loads, depending on the powers read (only monitoring with audible alarm,
if any).

3. Installation

The appliance must be installed on a wall at a height of 1.5 m off the floor in a suitable position for correctly
detecting the ambient temperature. It must not be installed in niches, behind doors and curtains or in areas
affected by sources of heat or atmospheric factors.
The timer-thermostat is a wall-mounting device that can be installed directly on a wall or on 2 and 3 module
back boxes.
It should be used in dry, dust-free places at a temperature between 0°C and +40°C.

4.2 Multi-function input

Depending on how it is configured, the multi-function input can be used to activate various functions of
the timer-thermostat (see par. 7.8 and 7.9).
It is on when the two terminals of the figure are closed by a dry contact; vice versa if they are open, the
input is off. The contact must be SELV and free of potential.
The typical wiring diagram is the following:

4.3 Energy Probe 02960

For the timer-thermostat to be able to communicate with the energy probe 02960 it is necessary to use
the circuit board 02915 that is to be installed on the wall base.
Connect the circuit board 02915 and energy probe 02960 using a UTP CAT5E cable or better; the RJ9
phone connector for connecting to the probe must be wired in such a way as to have one pair of wires
between terminals 1 and 4 (outer pair) and the other between pins 2 and 3 (inner pair).

Take care to keep consistent connections at the terminals.

• A  blue

• B  white-blue

• GND  white-orange

4.3.1 Measurement of 2 or 3 phases

The energy probe 02960 comes with a single current probe (for measuring the consumption/
production of a single phase); to measure more than one phase it is essential to have more
current probes 01457 (one for each additional phase to be measured). Once connected, you

must enable the new channel (the new phase to be measured) using the menu described
in par. 7.12.1.

4.3.2 Saving the consumption data log

In order for the energy probe to save the consumption data log properly, the latter must receive
the time setting from the timer-thermostat; then the clock must be correctly set (see par. 7.3). The
energy probe can save the consumption data log for a very long time (up to 3 years), provided
that its power supply is not interrupted for more than 7 consecutive days (at each start the time
must be reset by the timer-thermostat).
If the probe should remain switched off for over a week, the entire switch-off period would be
reduced in any case to a week (at most) with a loss of consistency in the log view; in this case,
to avoid inconsistent readings, you may want to reset its data log.
Here are some typical examples of installation of the energy probe:

generation via a photovoltaic panel, the probe will record a NEGATIVE value, that
corresponds to energy generation (as opposed to consumption).
