TURNING ON / OFF WITH ANTI-FREEZE MODE ACTIVATED
In order to deactivate or activate freetime evo, press the key“ “, The device will be in OFF condition and the display will show the writing “OFF”
and the symbol “ “. If the programmable thermostat in set on winter operation mode (see user parameter PAr 6.0 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 PAr 1.0 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), 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), 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 has an input for connecting an optional remote probe. The remote probe can be used to detect room temperature or floor temperature
or other temperature. The remote probe can be connected to sense room temperature in case the programmable thermostat needs to be installed
in a location not suitable for sensing room temperature. Alternatively, the remote probe can be congured to measure floor temperature, a useful
function in underfloor heating systems. In case the installation requires the installation of a remote probe, it is necessary to connect a probe with the
characteristics listed in the section ‘TECHNICAL FEATURES’, to terminals 4 and 5 as shown in the connection diagram in the chapter ‘CONNECTIONS’.
If in doubt about the type of probe to be connected, please consult the manufacturer. Depending on the desired function for the remote probe, the
user parameter “PAr 3.0 Entc” must be set.
TIME / TEMPERATURE DISPLAY
By pushing the knob, the current time or the detected room temperature can be alternatively displayed.
If a remote probe has been connected to detect the floor temperature and has been congured for its temperature to be shown on the display, pressing
the knob will cycle between displaying Time, Room Temperature, and Floor Temperature.
The floor temperature is indicated on the display by the symbol ‘ ’.
The temperatures detected are shown corrected by the set Offset values (see user parameters PAr 2.0 OFS1 and/or PAr 3.0 OFS2).
WARNING:
The programmable thermostat, in order to optimize battery life, detects the room temperature every 3 minutes and, accordingly, decides on the
activation or deactivation of the relay. Immediate temperature acquisition can be forced by pressing the ‘ ’ button.
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.
