Wired room thermostat SALUS HTR23020 daily surface-mounted, white, 230V

SALUS HTR230V(20) temperature controller – precise control of thermal comfort

The SALUS HTR230V(20) temperature controller is a wired, daily model designed to control surface heating or cooling, especially in rooms with high thermal inertia. The device is an ideal solution for both installers and end-users looking for a reliable and easy-to-use temperature control system. Thanks to the ability to connect to a control strip, the controller can lower the set temperature based on the NSB (night temperature reduction) signal from a weekly controller.

Functionality and application

HTR230V(20) offers a wide range of possibilities, ensuring optimal thermal comfort in every room. The temperature is set using a knob, and the built-in control algorithms – PWM or hysteresis – guarantee precise regulation. The controller works perfectly in underfloor heating systems, where stable temperature is crucial. Additionally, the NSB function allows for automatic temperature reduction at night, which translates into energy savings.

Key features and benefits

• Quiet operation: Thanks to the use of a TRIAC, the controller operates silently, ensuring comfortable use.
• PWM algorithm: Pulse width modulation (PWM) enables precise temperature control, especially in systems with high thermal inertia.
• NSB function: Automatic temperature reduction at night allows for energy savings and increased comfort.
• Thermostatic valve protection: The VP function protects valves from getting stuck, preventing their damage and ensuring long-term system operation.
• Heating/cooling switching: The ability to automatically switch between heating and cooling mode via the CO contact increases the versatility of the device.
• Wide adjustment range: The temperature adjustment range from 5°C to 30°C allows you to adapt the device to individual needs.
• Configuration jumpers: Allow you to adjust the controller's operation to the specifics of the installation (e.g. selecting the control algorithm, blocking cooling mode).

Technical parameters and compatibility

The HTR230V(20) controller is powered by 230V AC 50Hz and works with SALUS KL06, KL08NSB and KL04NSB control strips. The maximum triac load is 0.5A. The device has an IP30 protection class, which means protection against touching with fingers and against the ingress of solid objects larger than 2.5 mm. The net weight of the controller is approximately 90g.

Power supply: 230 V AC 50/60 Hz Triac load: 0.5 A Temperature adjustment range: 5 – 30°C Hysteresis: ± 0.5°C Protection class: IP30

Installation

The installation of the controller should be carried out by a qualified installer with appropriate electrical qualifications in accordance with applicable standards and regulations. Before installation, make sure that the device is disconnected from the power supply. The controller can be mounted both surface-mounted and flush-mounted (requires an appropriate mounting box). After connecting the wires, mount the housing and set the desired temperature using the knob.
