SALUS Wired Electronic Thermostat – Non-programmable HTR230
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 centre, 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.
Product compliance
The product complies with the following EU directives: 2014/30/EU, 2014/35/EU, 2011/65/EU. Full information is available at www.saluslegal.com
Note!
This document is a quick guide to the installation and operation of the
product and indicates its main features and functions. Detailed information is
available in the full manual, which is available at www.salus-controls.eu and
must be used for proper installation and operation of the product.
SAFETY INFORMATIONS:
Use in accordance with national and EU regulations. Use the device as
intended and keep it dry. Product for indoor use only. Please read the entire
manual before starting the installation and using the product.
INSTALLATION:
Installation must be carried out by a qualified person, with appropriate
electrical authorisations, in accordance with national and EU standards and
regulations. The manufacturer shall not be liable for failure to comply with
the manual.
NOTE:
There may be additional protection requirements for the entire installation.
The installer shall be responsible for compliance with such requirements.
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 compatibile with the following Salus wiring centre models: KL06 230V, KL08NSB 230V, KL04NSB 230V or directly to the actuator.
Symbols explanation:
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 “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
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 centre. 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
centre. Then, the HTR230(20) thermostat automatically reduces the temperature
setpoint on the knob by 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. TThe 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
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.
