In this diagram, the VS30 thermostat manages the NSB function, more details about NSB function can be found on the next page.

Note: In the KL06 wiring centre, the SL terminal is marked with an arrow icon .
NSB function and an additional temperature sensor is optional.

Temperature setting

Press any button to highlight the screen, then follow the steps below:

Manual mode

temperature settings
There are 4 temperature levels available. In manual mode only one temperature level is active (icon in the frame indicates which mode is currently choosen). For each temperature levels you can set a different temperature.

• Comfort mode
• Standard mode
• Economic mode
• Frost protection mode. Usually used in a longer period of absence or during the holidays (available only in heating mode).

Press any button to highlight the screen, then follow the steps below:

NSB function – automatic mode
The NSB (Night SetBack) function can automatically change temperatures on VS35 daily thermostats via VS30 programmable thermostat connected to a wiring centre (or another external clock). NSB function switches between comfortable temperatureand economic temperature.
To activate the automatic mode, select the icon A. On display together with the A icon, the controller indicates active temperature mode: or .

Press any button to highlight the screen, then follow the steps below:

Note: For the NSB function to work, it is necessary to connect the wirings properly. Connection diagrams can be found on the previous page.

Changing the HEATING / COOLING mode

Press any button to highlight the screen, then follow the steps below:

Note: Heating / cooling mode can also be set using the service parameter d18.

Offset function (temperature calibration)

The VS35 thermostat allows you to adjust the displayed temperature ± 3.0°C. You can do it according to the following steps:
Press any button to highlight the screen, then follow the steps below:

Note: You can also set the Offset temperature value using the service parameter d02.

Installer settings

Press any button to highlight the screen, then follow the steps below:

Note: To restore the thermostat’s factory settings, in step 2 set the PSuu to 47 code, and confirm the selection with the button.

dxx	Function	Value	Description	Default value
d01	Control method temperature	0	PWM algorithm	0
		1	Span ±0.25°C
		2	Span ±0.5°C
d02	Offset temperature	from -3.0°C to +3.0°C	If the thermostat indica- tes wrong temperature, you can correct it by ± 3.0°C	0°C
d03	Using a floor temperature sensor (S1, S2)	0	No sensor	0
		1	Sensor is connected
d04	External sensor used for air or floor temperature measurement (Function is active, when d03=1)	0	Thermostat measures the temperature only on the external sensor	0
		1	The sensor is used as a protection against overheating the floor
d05	Cooling mode control method	1	Span ±0.5°C	2
		2	Span ±1.0°C
d06	Type of thermoelectric actuator	0	NO – normally open	1
		1	NC – normally closed
d07	Valve protection	0	OFF	1
		1	ON
d08	Frost protection temperature	5-17°C	Frost protection / Holiday mode temperature	5°C
d12	Heating temperature limit	5-35°C	The maximum heating temperature that can be set by the user	35°C
d13	Cooling temperature limit	5-40°C	The minimum cooling temperature that can be set by the user	5°C
d14	Maximum floor temperature (this function is active  in heating mode when d04 = 1)	6-45°C	In order to protect the floor from overheating, heating will be turned OFF, when the maximum temperature of the floor sensor will be reached	27°C
d15	Minimum floor temperature (this function is active  in heating mode when d04 = 1)	6-45°C	In order to protect the floor, heating will be turned ON, when the minimum temperature of the floor sensor will be reached	10°C
d16	Lower floor temperature limit for cooling (this function is active  when d04 = 1)	6-45°C	In order to protect the floor, cooling will be turned OFF, when the minimum temperatu- re will be reached	6°C
d18	Operating mode HEATING / COOLING	0	Heating system	0
		1	Cooling system

Error codes

Error code	Description
Err02	The maximum / minimum floor temperature has been exceeded
Err03	Temperature sensor is faulty
Err04	Temperature sensor is shorted
