PROGRAMMABLE THERMOSTAT freetime evo
Wall-mounted, battery powered daily programmable electronic thermostat, allows to set the room temperature easily and precisely.
Suitable for controlling Heating and Cooling systems through a relay output with changeover contacts (C, NC, NO).
The regulation of the room temperature happens on two levels: Comfort and Economy (according to the set time program).
The minimum settable temperature is +0,5°C (anti-frost temperature): this allows to protect your heating system from any damage due to freezing,
if the freetime evo is turned off.
Featured with an input for the remote sensor connection, the device offers the possibility to regulate the Offset on the internal sensor or on the remote
sensor (with this parameter it is possible to correct any systematic reading errors due to the placement of the freetime evo or the remote sensor, in
areas which are not suitable for room temperature detection).

DIMENSIONS
TURNING ON / OFF WITH ANTI-FREEZE MODE ACTIVATED
In order to deactivate or activate the freetime evo press the key “ “, the device will be on OFF condition and the display shows the writing
“OFF” and the symbol “ “.
If the programmable thermostat is set to winter operation mode (see user parameter PAR6.0 H_C) and the anti-freeze mode is activated, the display
shows the related symbol “ “ and the set anti-freeze setpoint temperature (see user parameter PAR1.0 AFr); in this case the room temperature is
regulated according to the set value for the anti-freeze parameter.
OPERATION LOGIC
On “Heating” mode, when the detected room temperature, by the internal sensor or alternatively by the remote sensor, is lower than the set one
(manually or by program), the freetime evo will turn on the relay to start the boiler and the symbol “ “ appears on the display.
On “Cooling mode”, when the detected room temperature, by the internal sensor or alternatively by the remote sensor, is higher than the set one
(manually or by program), the freetime evo will turn on the relay to start the cooling system and the symbol “ “ appears on the display.
The switch from Heating mode to Cooling mode and vice-versa is not automatic, it has to be manually set using the user parameter “H_C” (see chapter
“USER PARAMETERS SETTINGS“).
REMOTE ROOM SENSOR
The freetime evo is featured with an input for the connection of a remote sensor (optional). The remote sensor can be used to detect the room
temperature if the programmable thermostat must be installed in a position which is not suitable for room temperature detection.
If the installation foresees a remote probe connection, it is necessary to connect a 10 KOhm at 25°C NTC type sensor to terminals 4 and 5 as shown
on the wiring diagrams at chapter “Wirings” and set the user parameter “PAR4.0 rEG” on “EHt” (external).
If you have any doubt about the type of sensor which can be connected, please ask the manufacturer for advise.
The temperature shown on the display related to the external sensor is distinguished by the symbol “ ” on the display.
TIME / TEMPERATURE DISPLAY
By pushing the knob, the current time or the detected room temperature can be alternatively displayed.
If a remote sensor is connected, by pushing the knob it is possible to show on the display, alternatively, the current time, the room temperature
detected by the internal sensor and the temperature detected by the external sensor.
If a remote sensor is connected, the freetime evo also shows the icon “ “ indicating that the displayed temperature is the one from the internal
sensor, or it shows the icon “ “ indicating that the shown temperature is the one detected by the remote sensor.
The temperature detected are shown corrected by the set Offset value (see user parameters PAR2.0 OFS1 and/or PAR3.0 OFS2).
WARNING:
The programmable thermostat, aiming to optimize the battery life, detects the room temperature every 3 minutes and, consequently, decides the
activation or deactivation of the relay.
DISPLAY BACKLIGHT
The display backlight is turned on if a key is pressed or when the knob is rotated.
The backlight is turned off automatically 20 seconds after a key has been pushed or the knob has been rotated or pushed.

INSTALLATION
WARNING
- To properly set the room temperature, install the programmable thermostat far from heat sources, airstreams or particularly cold
walls (thermal bridges).
If a remote sensor is used, the note is applied to the sensor and not to the programmable thermostat.
- In order to connect the external probe use cables with minimum section of 1,5 mm² and with a maximum length of 15 m. Do not
pass the cables through the pipes where the power lines run.
- If the load controlled by the relay of the programmable thermostat operates with mains voltage, the connection must be made via
an omnipolar switch complying with current standards and with a contact opening of at least 3 mm in each pole.
- Installationandelectricalwiringsofthisappliancemustbemadebyqualiedtechniciansandincompliancewiththecurrent
standards.
- Before wiring the device be sure to turn the mains power off.

PELLET STOVE CONTROL
The programmable thermostat can be set to regulate the room temperature for turning on and off a pellet stove.
The relay output must be connected to the input for the activation/deactivation of the pellet stove.
Aiming to limit the on/off switches number of the stove, set the parameters as shown below:
- HYSt: Room temperature regulation hysteresis at 1,0°C
- tMIn: Minimum relay acrivation time at 30 minutes

INSERTING / REPLACING THE BATTERIES
In order to insert / replace the batteries, proceed as follows:
1. Open the plastic slider placed on the front of the product, which
gives access to the battery compartment, sliding it to the left.
2. Extract the batteries, levering with a tool if needed.
3. Insert the new batteries, respecting the polarities indicated. The
batteries must be alkaline at 1.5V type AA.
4. Check the clock accuracy and, if necessary, adjust it.
WARNING
- If the batteries need to be replaced, dispose them in the special containers for recycling.
- Replace the batteries within about 5 minutes in order not to lose the set time; keep in mind that the clock stops at the moment when the
batteries are removed and so it must be eventually updated.
BATTERY LEVEL
The display always shows the battery life status with the symbol “ ”.
The battery life is full if inside the symbol all the three indicators are on.
On the contrary, the batteries are low and must be replaced if the display shows the symbol “ “ (with only one bar left).
WARNING
- If the display shows the blinking writing “bAtt“ and the symbol “ “ (completely empty), it means that the battery power is too
low to allow the device to work properly and the output will always be off.
In this case the freetime evo won’t regulate the temperature and the time schedule, the time and the detected room temperature won’t
be displayed.
