INSTALLATION AND OPERATION MANUAL

6.
SETTING TEMPERATURE
Use “
” buttons to set the desired temperature value. Pressing on
e of the buttons for the
first time activates the backlight, pressing it repeatedly lowers or raises the temperature in
increments of 0.1°C. The longer the button is pressed, the faster the values change. Confirm
the temperature change with the central button or wait until the set value stops flashing and is
stored. The factory setting is 20
°C.

THERMOSTAT CONFIGURATION
Press and hold the central and right buttons for approximately 2 seconds to enter the setting
mode. Configure the thermostat in the
following way: choose a required parameter with “
”
and “
” buttons, use
the central button to enable the introduction of changes, and change the
value using “
” and “
”, then confirm the modified value with the central button. The
following parameters may be changed:
•
Temperature range limit
–
low (LO)
This parameter allows you to limit the temperature range to be set. This parameter
limits the lower values of the range.
Default value 5°C.
•
Temperature range limit
–
high (HI)
This parameter allows you to limit the temperature range to be set. This parameter
limits the higher values of the range.
Default value 35°C.
Example:
To set a preset temperature between 18
°C
and 23
°C
, you must set the "LO" value to
18
°C and the "HI" value to 23
°C
.
•
Hysteresis/PWM (H)
Two operational options for activating the heating algorithm are available: hysteresis or
PWM.
In the case of hysteresis, the device is activated based only on a difference between the
preset and current temperature. The parameter determines the accuracy of room
temperature control. You may set the hysteresis between 0.2
°C and 10
°C, and the
factory setting is 0.4
°C.
Setting the value to 0.0 will put the thermostat into PWM mode.
PWM is a more advanced method to achieve the preset temperature. It is suited for
systems with underfloor water heating. It is used to limit room temperature fluctuations.
Unlike in on/off controls the current status of the transmitter depends not only on the
current difference between the preset and measured temperature but also on the past
changes of temperature. PWM operates with fixed parameters:
✓
Minimum relay activation time of 3 minutes,
✓
Number of cycles per hour - 4
✓
Operating range of the PWM algorithm of 0.7
°C.
•
Temperature sensor correction (C)
It is a value that is added to or subtracted from the measured temperature value. It ad-
justs the displayed temperature within the range of +/- 5
°C. The function is convenient
if the thermostat is located in a slightly warmer or cooler area of the room.
•
Pairing mode (P)
Used to establish radio communication between the thermostat and receiver(s). For
pairing mode, see section 12.1.
•
Reset (rEs)
When you change the value from 0 to 1, the thermostat restores factory settings.
•
Exit (ESC)
Press the central button to make the thermostat exit the service mode.
Exit the menu at any time by pressing the left "
” button of the knob.
