SALUS Thermostat RT520 User Manual Overview

Summary of Contents

• Page 1: RT520 thermostat - full user manual
• Page 2: Introduction Product compliance Safety informations Product overview Example of boilers compatible with the OpenTherm OT+ 4.0 protocol Package content Proper thermostat location Connection description Before you start (first power up) LCD icon description Button description First power up sequence and configuration User settings Manual mode Schedule mode - programming schedule BOOST mode - hourly temperature override (+Hr) Control and Heat/Cool settings Time/Date Holiday mode Factory reset Error codes Battery change Cleaning and maintenance Technical informations Warranty
• Page 3: Product overview The RT520 room thermostat switches the heating system on and off as necessary by sensing the air temperature. Turning a room thermostat to a higher setting does not make the room heat up any faster. The heating system will not work if a time switch or programmer has switched it off. The best way to set the room thermostat is to find the lowest comfortable temperature and leave it alone. Adjustments above the comfortable setting will waste energy and increase costs. Thermostatic radiator valves (TRVs) can allow for different temperatures in individual rooms. Room thermostats need a free flow of air to function properly and should not be obstructed. The thermostat is compatible with OpenTherm OT+ 4.0 version. OpenTherm protocol enables two-way communication between the heating boiler and the thermostat, increasing energy efficiency. Make sure your gas combi boiler is compatible with OT + 4.0 communication protocol.
• Page 4: Example of boilers compatible with the OpenTherm OT+ 4.0 protocol includes various models from different companies. Vokera offers models such as E-Tec S, E-tec Plus, and Linea HE. Alpha Heating provides models like E-tec and Evoke. Viessmann has multiple models including Vitodens 100W and Vitodens 200-W. Vaillant features models like i25 and i29 Condensing Combination Boilers. Worcester offers Greenstar models, including CDi Classic and Highflow CDi. Intergas has models such as Rapid and Rapid Plus. Navien provides NCB and Avanta models. Ravenheat includes Quinta Pro and Gas 110 Eco. Vokera also has models like Verve and Vision System, which operate in heating mode only.
• Page 5: Montage Package content RT520 thermostat Back housing 2x AA batteries Short instruction Mounting screws Proper thermostat location The ideal position for thermostat mounting is about 1.5m under floor level, far from heating or cooling sources. The thermostat cannot be exposed to sunlight or extreme conditions like drafts.
• Page 6: Connection description Boiler connection Pump / Valve connection KL08NSB underfloor heating wiring center connection Boiler connection details include contacts for ON/OFF thermostat. Power supply is 230V. Voltage-free output is indicated by NO, COM, NC. OpenTherm communication wire is represented by A, B. 230V AC voltage output is denoted by SL. Maximum of 6 per zone for connections. Symbols explanation provides clarity on the components.
• Page 7: Before you start (first power up) LCD icon description includes various indicators such as text bar, temperature unit, and heating mode status. The button description outlines the functions of each button, including MENU/RETURN, SELECT, UP, DOWN, BOOST, and MANUAL. The LCD screen can be activated by using any button.
• Page 8: First power up sequence and configuration Make the receiver connections and power the receiver before inserting the batteries into the thermostat. After inserting the batteries, the thermostat will power up. Choose your language and then press to confirm. Set the time format and then press. Set the hour and then press. Set the year and then press. Set the month and then press. Set the minutes and then press. Set the day and then press. Select the week format and then press to confirm.
• Page 9: - Press to confirm. - Enable or disable DST (Daylight Saving Time). - When OpenTherm is connected, the device software will automatically adjust to the OpenTherm settings. - Select your temperature accuracy.
• Page 10: TPI (Time Proportional & Integral) is a self-learning, time-proportional algorithm. TPI type of regulation ensures economical system operation through more accurate temperature maintenance during controlling process and limits overload conditions. The advantage of this system is the minimization of energy consumption and significant savings. RT520 offers 3 types of TPI control: for radiator, for underfloor heating, and for electric heating. Span is the difference between the measured temperature and the set temperature.
• Page 11: The optimization function is an energy-saving algorithm used for efficient control of the heating device, ensuring better thermal comfort at certain times of the day. When the OPTIMUM START function is active, the thermostat sends a heating signal to the heat source beforehand so that the preset temperature in the room is reached at the time specified in the schedule. When the OPTIMUM STOP function is active, the thermostat, taking into account the inertia of the system, switches off the heat source earlier, keeping the temperature set in the schedule. The thermostat will go to the main screen.
• Page 12: OpenTherm - Hot Water configuration RT520 can be configured in Hot Water OPENTHERM system. To configure it follow steps below: Press the button. Using the navigation buttons, navigate to the Hot Water submenu. Using the adjustment buttons, adjust the temperature and then press the button. The thermostat will return to the main screen. Press any button. The text bar indicates that hot water is in operation.
• Page 13: User settings In manual mode, the thermostat maintains a constant temperature set by the user. A hand icon is displayed when manual mode is active. To set temperature use the appropriate button. Confirm your choice using the designated button. The thermostat will maintain the temperature until manual change or manual mode exit. To exit manual mode, press and hold the button for 3 seconds.
• Page 14: Schedule mode allows users to set temperature setpoints for specific periods of time. Programmed schedules should utilize all time periods. Users can select the program type: 5+2 for working days and weekends, All for the entire week, or Individual for a daily schedule. Confirmation is required after selecting the program type. Users can set the hour and minutes for each schedule. Temperature settings can also be adjusted for each time period. The process should be repeated for all time periods.
