SALUS HTR230 Electronic Thermostat User Manual

SALUS HTR230 Electronic Thermostat

Introduction

HTR230(20) is a surface-mounted (or on a flush-box) room thermostat dedicated for surface heating/cooling control, characterized by high thermal inertia. It is connected to the wiring center, through which you can lower the set temperature on it, receiving a signal NSB (night temperature reduction) from the weekly thermostat. The room temperature could be set by knob use. Thanks to the built-in algorithms, it offers much better temperature control accuracy than traditional mechanical thermostats. The thermostat is characterized by silent operation.

Mounting screws

Proper thermostat location

The ideal position for 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

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:

Montage

Make sure that the thermostat is not connected to the 230V AC. Remove the knob by pulling it towards you, and then open the front cover as shown in the figure above

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

Fold front and back housing of thermostat. The thermostat is configured. Use the knob to set the temperature setpoint

Jumpers for additional settings

The functions of the HTR230(20) thermostat can be switched on and off by jumpers. Please refer to the table below:

Jumpers 1 to 5 correspond to the number of actuators connected. This jumper is factory set to position 1, which means that the thermostat controls one actuator. Depending on the number of actuators used, the jumper position must be changed to ensure optimal operation of the temperature thermostat.

Selecting the heating or cooling mode
The heating or cooling mode is based on the voltage sent to the CO terminal. 0V AC at the CO terminal – the thermostat is in heating mode. 230V AC at the CO contact the thermostat is in cooling mode.

Cooling blocking function

Cooling on: Set the jumper to ON. The thermostat will work in cooling mode if 230V AC will appear at the CO terminal. The LED lights up blue when the thermostat sends a signal for cooling.

Night setback – NSB function
The NSB (Night Set Back) function enables automatic reduction of the temperature setpoint on the daily thermostats, via the programmable thermostat connected to the wiring center. The temperature change takes place between day and night temperatures. When the night mode is activated, the programmable thermostat sends a voltage signal to the daily thermostats via the wiring center. Then, the HTR230(20) thermostat automatically reduces the temperature setpoint on the knobby at 2° or 4° (as set on the SETBACK jumper). In heating mode, the temperature is lowered when 230 V AC voltage appears at the NSB input.

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

Valve Protection Set the jumper to ON – to enable or OFF – to disable the function. This function activates the thermostatic valve for 5 minutes once a week to prevent the valve against stuck (caused by limescale)

Operation algorithm selection
The thermostat gives a possibility to choose the mode of controlling the room temperature by PWM algorithm (default) or hysteresis +/-0.5°C. The PWM algorithm is designed for underfloor heating (for heating systems with high inertia)– to precisely maintain the room temperature.
