Wired digital thermostat – non-programmable
Model: HTRS230(30)
User manual

Ver. 1
Date of issue: 24 VI 2020
Power supply: 230V

Introduction

The HTRS230V(30) from SAWS Controls is a digital, wired and surface-mounted (or on a flush-box) nonprogrammable room thermostat dedicated for surface heating/cooling control, characterized by high thermal inertia. It is connected to the wiring center. The thermostat does not have the function of creating schedules – it lowers the set temperature via the wiring center after receiving the NSB signal from the weekly 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.

Symbols explanation

Note : The following designations are used interchangeably for products:
→ = SL
= NSB

Montage

Make sure that the thermostat is not connected to the 230V AC. Then open the front housing using a screwdriver as shown above.

Connect the thermostat properly. Please refer to the “Connection Description” section. Mount the thermostat using the designed screw holes.

Slide the thermostat on the back cover. The thermostat is configured for operation. Use buttons to set the temperature setpoint.

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.

– Comfort temperature mode
– Economic temperature mode
– Frost protection mode is Usually used during the period of long absence, or during the holidays (only available in mode). HEATING

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 and economic temperature mode.
To activate the AUTO mode, select the icon A. Together with the icon, the thermostat shows the active temperature mode on the display: or .

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.

Calibration of displayed temperature – “offset” function

The thermostat allows to correct the displayed temperature by ±3.0°C.
Follow the steps below:
Press any button to highlight the screen, then follow the steps below:

Note: Calibration of the temperature can also be set in the installer parameters (parameter d02).

Heating / Cooling mode

Manual change:
Modes are indicated by symbols. Press and hold the 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 D 19 thermostat parameter is set to “1”, then cooling is blocked for a single room. When the cooling function is blocked, no message is displayed.
