Parameter 19 (Ftc) – Floor Temperature Calibration
This parameter defines the offset value for floor temperature. Should the external floor
temperature sensor not be correctly calibrated then temperature changes are able to be
adjusted by up to +/- 9.5°C or +/- 17°F. This value will be added or subtracted from the floor
temperature sensor reading.
Factory default value is 0.
Parameter 20 (HYS) – HYSTERESIS (HYS)
The hysteresis value for temperature control. The thermostat will stabilize the temperature
with selected hysteresis. For example, if the SET POINT is set for 25°C and HYSTERESIS
is set for 0.5°C the thermostat will change the state to HEATING if the temperature will be
lower than 24.5°C and it will change the state to idle if temperature reaches 25.5°C.
The hysteresis can be changed from 0.1°C up to a maximum of 9.5°C in Celsius mode and
from 0.1°F to 17°F in Fahrenheit mode.
Factory default values are 0.5°C or 0.9°F.
Parameter 21 (dIF) – Temperature difference to send to controller
The thermostat will send a new temperature to the gateway only in case if the temperature
change is greater or equal than the value specified in this parameter.
From 0.1C to 1.0C can be chosen.
Factory default value is 0.2C
Note:
The thermostat is very sensitive to changes of ambient temperature and can often vary
by ±0.1C, therefore it is recommended to set this parameter from 0.2 and above to reduce the
load on your Z-Wave network.
DISPLAY BRIGHTNESS
The thermostat has two states of brightness.
Active state – when press any key and commence adjustments.
Inactive state – after five seconds of inactivity it will revert to inactive state.
The display brightness in either state can be adjusted.
Parameter 22 (brH) – Display brightness high level
The brightness level can be selected in the active state from values 1 (lowest brightness) to 4
(highest brightness) but the level cannot be lower than the level of brightness for the inactive
state (param 23).
Factory default value is 4.
Parameter 23 (brL) – Display brightness low level
This parameter defines the brightness level of the display in the inactive state. The level can
be selected from values 1 to 4 but the level cannot be higher than the level of brightness for
the active state (param 22).
Factory default value is 3.
Parameter 24 (Abr) – Auto brightness
The thermostat can adjust its display brightness automatically depending on the illumination
of the ambient environment. The comfort brightness of the screen can be chosen depending
on the room illumination in Parameters 25, 26 and 27.
Value 1 = Active the function, Value 0 = Inactive the function
Factory default value is 1.
Note:
The illumination of the environment can be checked at any time in the centre of the
display (on time position) in the device MENU on Parameter 24 or via your Z-Wave gateway
Parameter 25 (Ab1) – Auto brightness level 1 max lumens
The value indicates the maximum level of ambient illumination during which the brightness of
the display will be at level 1 (at the lowest level). For example if this parameter value is set 30
and the ambient illumination is in range 0-30 the display will be in lowest brightness level. As
soon as the illumination will be 31 or higher the display brightness will be changed to Level 2.
Factory default value is 30.
Parameter 26 (Ab2) – Auto brightness level 2 max lumens
This parameter indicate the maximum illumination for display brightness level 2. In case if the
illumination is in range Parameter 25 (Ab1) - Parameter 26 (Ab2) the display brightness will
be on level 2. If the illumination drops below the value of parameter 25 the brightness of the
display will be decreases to level 1, and if the illumination increases beyond the value of
parameter 26 the display brightness will rise to level 3.
Factory default value is 200.
Parameter 27 (Ab3) – Auto brightness level 3 max lumens
This parameter indicate the maximum illumination for display brightness level 3. In case if
ambient illumination raise above this value the display brightness will be changed to Level 4
Factory default value is 3000.
Parameter 28 (bsA) – Basic Sat Action
This parameter defines to which mode the thermostat operating mode will be changed to if
the Basic Set command is received.
If the received value of the Basic Set command is 0 (OFF state) the thermostat will go to MAN
mode and switch off the heating element (IDLE mode).
If the received value of the Basic Set command is 1 or higher (ON state) the thermostat will
change its mode regarding the value defined in this parameter.
If the parameter value is 1 the thermostat will go to the COM operating mode, value 2 is for
the TIME mode, Value 3 is for the DRY mode, Value 4 is for the ECO mode, Value 5 is for the
VAC, Value 6 is for the MAN.
If the parameter value is 6 (change to manual mode) and the Basic Set value is 1 or higher
(ON) the thermostat will go to the MAN mode and switch ON the HEAT mode.
Factory default value is 6.
Parameter 29 (nEt) – INCLUSION / EXCLUSION MODE
If the thermostat is included in the z-wave network the antenna will be indicated in the main
display and Inc will be indicated in the Param value. If the thermostat is not included in the
network, no antenna will be indicated in the main display and the Param value will be ECL.
To include or exclude the thermostat into/from your home automation gateway, activate
inclusion or exclusion mode on your gateway then go to Param 29 in the device Menu and
press “+” key for inclusion and the “-” key for exclusion.
For more details go to point “Z-Wave Functions” – “Network“of this manual.
Parameter 30 (Prr) – Power Meter values & reset
The Heltun thermostat monitors the load and total power consumption. The current load is
indicated in this Param values in the center of display (time position) in W. The data of total
consumption in kWh is indicated in the top right corner of the display.
If the device is included to the Z-Wave network it will also send the data of the current load
and total consumption to the main controller.
The thermostat, even when the electricity is disconnected, maintains the electric
consumption record in its memory.
To reset the consumption memory press and hold “+” key (about 3 seconds) until the
parameter total consumption value will be changed to 0.

6) PA – Power reg Air sensor: Regulation is based on the time set by Params 05 and
06 but also controlled by the internal air temperature sensor ensuring that the room
temperature remains within the set limits. The air temperature limits are specified in Params
13 and 14.
7) PF – Power reg Floor sensor parameters: Regulation is based on the time set by
Params 05 and 06 but also controlled by the floor temperature sensor ensuring that the floor
temperature remains within the set limits. The floor temperature limits are specified in
Params 15 and 16.
For example:
In FA mode the SET POINT is set to 30°C, AtL is set to 24°C and AtH is set to 27°C:
a) If floor temperature is lower than 30°C and the room temperature is lower than 27°C the
thermostat will operate in HEATING mode.
b) If the floor temperature is higher than 30°C or the room temperature is higher than 27°C
then the thermostat will go to IDLE mode which switches off the heater.
c) If the room temperature is lower than 24°C the thermostat will operate in HEATING mode
even though the floor temperature is higher than 30°C.
Attention:
Be careful when setting the lower limitation (Param 13 - AtL and Param 15 – FtL)
to be sure that the value is not too high and it can be reached. Otherwise the thermostat will
always operate in the HEATING mode.
Note:
For safety reasons the thermostat will go to the IDLE mode if the floor temperature
reaches 40°C despite the parameter settings.
Note:
If there is no floor sensor installed or it becomes damaged (indicated by ” – “ in the
“FLOOR TEMP”) the regulation mode (A) will be automatically selected as the source
