SALUS HTRP230(50) Wired Digital THERMOSTAT Quick Guide


SALUS HTRP230(50) Wired Digital THERMOSTAT 



The HTRP230V(50) from SALUS Controls is a stylish and accurate 5/2 or 24h programmable electronic thermostat with a large, easy-to-read Liquid Crystal Display (LCD). It is a surface-mounted temperature controller dedicated to surface heating/cooling, characterized by high thermal inertia. It is connected to the wired wiring center KL08NSB. The thermostat has the function of creating your own schedules. It can control group (SLAVE) thermostats – via the wiring center, it sends them an NSB (nighttime temperature reduction) signal and switches them to economic temperature. The time schedule is common to all thermostats (according to weekly (MASTER) thermostats), but temperatures are set individually on each thermostat. Thanks to the built-in algorithms, it offers much better temperature control accuracy than traditional mechanical thermostats. The thermostat is characterized by silent operation. The controller is characterized by silent operation.

Package content

Proper thermostat location


The ideal position to thermostat mounting is about 1,5m under floor level far from heating or cooling sources. In addition, the thermostat should not be installed behind curtains or other obstacles or in places with high humidity, as this will prevent accurate measurements of room temperature. The thermostat must not be exposed to sunlight. Do not place the thermostat on an outer wall.

Connection description

Note: The thermostat is compatible with the following Salus wiring center models: KL06 230V, KL08NSB 230V, KL04NSB 230V, or directly to the actuator.

  1. Make sure that the thermostat is not connected to the 230V AC.
    Then open the front housing using a screwdriver as shown above.SALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.5
  2. Connect the thermostat properly. Please refer to the “Connection description” section. Mount the thermostat using the designed screw.SALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.6
  3. Slide the front of the controller over the thermostat on the back of the controller cover. The thermostat is configured. Use buttons to set the temperature setpoint.SALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.7

The date and time can be set at any moment during thermostat use. Press any button to highlight the screen, then press and hold for 3 seconds, then follow steps from 3 to 9.

Manual mode – temperature setpoints

3 temperature levels are available. In manual mode, only one temperature level is maintained for the entire day. The icon in the frame indicates which mode is currently active. A different temperature can be set for each level.

  • SALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.14Comfort temperature mode
  • SALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.15Economic temperature mode
  • SALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.16Frost protection mode is Usually used during the period of absence or during the holidays (only available in HEATING mode).

The thermostat also has 2 additional modes:

  • The PARTY mode sets the comfortSALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.14 temperature for a user-defined time (maximum 9 hours 50 minutes).
  • The HOLIDAY mode sets the frost SALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.16protection mode for a user-defined time (maximum 99 days).

Temperature setpoint

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


AUTO mode – NSB function

The NSB (Night Setback) function enables automatic reduction of the temperature setpoint on the HTRS230(30) SLAVE thermostat, via the HTRP230(50) programmable MASTER thermostat connected to the wiring center (or another external clock). The temperature change takes place between the comfort temperature mode SALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.14and SALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.15the economic temperature mode.
To activate the AUTO mode, select the icon. Together with the icon, the thermostat shows the active temperature mode on the display: SALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.14orSALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.15.
Press any button to highlight the screen, then follow the steps below:


Note: For the proper NSB function work, an appropriate cable connection is required. The connection description is on the previous page.

Schedule programming

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


Repeat steps 4 to 6 to set the time and temperature for further points of the schedule. No time (–:–) on the display means that the thermostat will skip the time interval. 6 points are available for the schedule.

Heating / Cooling mode

Manual change:
Modes are indicated bySALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.24 symbols. Press and hold SALUS-HTRP230(50)-Wired-Digital-THERMOSTAT-FIG.25the button to enter the menu, then use the button to select the Heating / Cooling mode change setting. Confirm changes using the button. Now use or buttons to set the heating or cooling mode. Confirm by button.

Automatic change (via CO terminal): The heating/cooling mode can be changed automatically via the CO terminal in the thermostat. If a 230 V AC power supply is connected to the CO terminal – then the thermostat automatically switches to cooling mode. If you want to use this function, then you have to change the value of the D18 parameter to “1”.

Cooling blocking:
When the D19 thermostat parameter is set to “1”, then cooling is blocked for a single room. When the cooling function is blocked, no message is displayed.

Installer mode

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


Note: To restore default settings – set the P47 code during 2 steps and then confirm your choice using or buttons.
