1. How does the DAILY TEMPERATURE REGULATOR work?
- A daily temperature controller is designed to maintain comfortable conditions in a room in accordance with a set constant temperature set by the user or by executing the commands of the main (weekly) controller. It has no scheduling function (operating modes). We are able to choose between two types of the daily controller:
  • independent daily regulator (e.g. RT310, connected directly to the boiler)
  • daily in a wired underfloor heating system (e.g. VS35W/VS35B)
2. How does the WEEKLY TEMPERATURE REGULATOR work?
- A Weekly Temperature Controller is one on which you can set a schedule. It controls the daily regulators, but does not set a desired temperature for them. The weekly regulator changes the heating mode (day/night) and sends a signal to the daily regulators to also change the operating mode. We are able to choose between two types of the weekly regulator:
  • independent weekly regulator (e.g. RT510, directly connected to the boiler)
  • weekly in a wired underfloor heating system (e.g. VS30W/VS30B)
3. MANUAL MODE - what is it?
- In manual mode (marked on the screen with a hand icon) the controller maintains a constant set temperature until the user changes it again.
4. AUTOMATIC MODE, or how does the schedule in the weekly regulator work?
- In the automatic mode (marked on the screen with the calendar icon) the regulator maintains the temperature set according to the schedule selected by the user.
  There are 3 schedule configurations available in SALUS Controls regulators:
  • 5+2 (Monday to Friday + Saturday and Sunday)
  • Individual programs for each day of the week
  • Same program for the whole week
5. What is the optimalization function?
- The optimization function is an energy-saving algorithm for controlling a heating device, providing better thermal comfort at set periods of time. When the OPTIMUM START function is active, the controller sends a heating signal to the heat source in advance so that the desired temperature is reached at the set time. When the OPTIMUM STOP function is active, the controller - taking into account the system inertia - shuts down the heat source earlier and maintains the set temperature in the schedule.
6. Heating control algorithms, i.e. operation of regulators according to: HISTERESIS, PWM, TPI and ITLC
- HISTEREZA and PWM
  Hysteresis is the difference in temperature between switching the heater on and off. PWM converts an analogue signal into a sequence of pulses, the duration of which is proportional to the control signal and which are repeated in a constant time cycle. PWM (Pulse Width Modulation) is often used to control the floor. Why? If the ON/OFF regulator (hysteresis) is used in a slow-reaction system (e.g. underfloor heating), underheating and overheating cycles cannot be avoided. It is difficult to maintain a constant temperature, because the regulator starts when the temperature drops below the set point. With a system with a high thermal inertia, the room temperature can continue to drop when the controller is switched on. On the other hand, the controller switches off when the temperature is higher than the set value.. When the controller is switched off, the room temperature continues to rise because the heated concrete floor has to give off heat to the environment. On the other hand, the PWM controller works longer or shorter in each cycle, depending on the difference between the measured and set temperature. Unlike an ordinary thermostat that works according to the Hysteresis, the PWM controller does it differently. It selects "several-minute time pulses" for switching the heating element on and off in such a way as to keep the room temperature close to the set values. Even when the temperature has been reached, it still heats up with the impulses to maintain comfort in the room.
  
  TPI, ITLC
  TPI (Time Proporcional and Integral) is an algorithm that has a simple memory in its software that "learns" how to achieve and maintain room temperatures. It has a basic computing capability: It "works" with the collected data and current temperatures, "predicting" how long the heat must be supplied (the boiler must be on). This is a kind of "intelligent control", as the heat supply takes so long as to reach the set point and switches off, increasing energy efficiency. Similarly to PWM, the TPI works according to cycles whose length is measured in quantities per hour. During normal use, it is difficult to notice the difference in the way the heating is used. You can see, however, that the controller works shorter when it approaches the set temperature. When the setting is reached, the periods of operation become short in order to maintain the temperature. TPI calculates the rate at which the room loses heat and replenishes it, preventing it from cooling down. ITLC (Internal Temperature Load Compensation) is a modified TPI. The mechanism of operation is the same, but in this algorithm additional functions have been implemented to limit overdrive states in particular types of heating and selection of a particular type of heating in the controller. Depending on the heating type, the controller "learns" the room faster and maintains the set temperature more stable.
7. What is NSB function?
- The NSB (Night Set Back) function gives you the possibility to automatically lower the set temperature on the daily regulators via a programmable (weekly) controller connected to the wiring centre. The temperature change takes place between day and night temperatures. A weekly regulator installed e.g. in a living room, via a wiring centre, sends a signal to the daily regulators. Then the daily regulators automatically reduce the set temperature according to the value set on them.
8. What is the VP valve protection function?
- All underfloor heating controllers have a VP (Valve Protection) function, which protects the thermostatic valves from stagnation; once a week the actuator opens and closes, even if the system is not in operation (e.g. outside the heating season). The function is designed to protect the thermostatic valves from stagnation or jamming.
9. What is the WARM FLOOR function?
- The purpose of the function is to keep the floor warm even when there is no need to heat the room. The user can choose three levels of keeping the floor warm. The parameter can be activated for your own convenience to keep the floor warm at all times, but you should remember about the economy of using this function. This option is available in the Quantum SQ610/SQ610RF temperature controller.
10. What is the HOLIDAY mode?
- The HOLIDAY mode sets the freezing protection temperature for a period of time defined by the user.
11. What is the PARTY mode?
- PARTY mode sets the comfort temperature for a period of time defined by the user.
12. What is the SLEEPING mode?
- The SLEEPING mode suspends all functions of the temperature controller, which is the best way to save batteries. The SLEEPING mode works especially during prolonged absence of household members and outside the heating season.
13. What is a MINIMUM TIME OF SHUT-OFF?
- This is a parameter that determines the minimum time between turning off and next turning on. The regulator must wait this time before starting up again.
14. How does PIN code lock work?
- There are two variants of securing the controller with a PIN code: 1. the code will only block the installer's settings menu, 2. the code will completely block the controller. The code can be set both from the application and from the controller.
  
  The function is dedicated to administrators of buildings, holiday facilities, owners of hotels and premises for rent. PIN code lockout makes it easy to keep control over energy consumption.
15. What is FIRST OPEN function?
- The First Open function makes it easy to install the actuators on the manifold, so the device is ready for installation immediately after taking it out of the box.
16. What is the PARING OF THE DEVICES?
- Pairing is the process of establishing a connection between devices to enable them to communicate wirelessly.
17. What is the ADDITIONAL TEMPERATURE SENSOR (FLOOR, AIR) for?
- An additional temperature sensor (e.g. FS300) installed in the floor protects the underfloor heating - it detects too low or too high temperatures. Used as an air sensor, it allows measuring room temperature at a distance.
18. What is the CH manifold?
- In particular types of installations (system with radiators, underfloor heating system, mixed sets), the manifold - as the name suggests - splits the heating medium (water) into all loops. In simple terms, the manifold ensures even heat transfer in the building by controlling the speed and direction of water flow in the system. It connects the heating zones into one system and enables energy savings. A single manifold has a form of a bar equipped with valves for connecting heating pipes. The whole system consists of two bars - supply (top) and return (bottom), connected by steel holders.
  Elements of the manifold:
  • BARS made of stainless steel, brass or artificial material (e.g. polyamide)
  • VALVES (e.g. shut-off, regulation and measurement valves)
  • VENTS
  • Flow meters (rotameters)
  The manifold is flush-mounted or surface-mounted in a special installation box that resembles a classic inspection cabinet.
19. What is a HEATING ZONE?
- It is a room or several interconnected rooms, in which we have the ability to regulate the temperature regardless of the heating parameters set for the rest of the building. The same temperature is maintained in a given heating zone.
20. What is a HEATING LOOP?
- A heating loop is a system of surface heating pipes formed in the shape of a spiral or meander. The way the pipes are laid in the heating loop depends on the type of the room, its shape, purpose, as well as the layout of walls, windows and floor structure. The length of one heating loop of the floor heating is maximum 100 m.

1. A sensor connected to the controller detected overheating of the floor:
- Set the correct heating medium supply temperature or change the regulator setting in the Installer's Parameters: MAXIMUM FLOOR TEMPERATURE FOR HEATING.
2. The controller has detected a failure of the additional sensor or does not react to its commands
- • If the sensor is connected to S1/S2 input, check the wiring.
  • Check the wiring of the sensor for damage (e.g. breakage).
  • Check the wiring of the sensor for damage (short circuit). Sensor resistance for 25°C=10kΩ.
  • Check the setting in the Installer Parameters: ADDITIONAL INPUT S1/S2. Determine whether the parameter related to the TEMPERATURE SENSOR has been activated.
3. The controller has lost communication with the wiring centre:
- Check if the wiring centre is on and the green Status Network LED is constantly on: • If so, force a signal to heat from the controller. • If the Status Network LED flashes on the wiring centre, reinstall it in the system according to the operating instructions and pair the controller with this wiring centre.
4. The controller has lost communication with the wiring centre
- Check if the wiring centre is on and the green Status Network LED is constantly on:
  • If so, force a signal to heat from the controller.
  • If the Status Network LED flashes on the wiring centre, reinstall it in the system according to the operating instructions and pair the controller with this wiring centre.
5. The regulator has lost communication with the TRV thermostatics radiator valve, SR600, SPE600
- • Check the batteries in the thermostatics radiator valve.
  • Force a signal to heat from the regulator and check if the thermostatics radiator valve.
  • If the LED on the TRV valve is flashing, repeat the procedure of pairing the valve with the regulator.
6. The wiring centre has lost communication with the zone controller
- • Check the power supply of the regulator.
  • Force a signal to heat from the controller.
  • Reinstall the controller if necessary.
7. The wiring centre has lost communication with CO10RF/UGE600 coordinator
- • Check if the wiring centre is on. The Status Network LED should be on permanently. Force identification from the coordinator/gateway.
  • If the Status Network LED flashes on the wiring centre, reinstall the wiring centre and pair the controls with it.
8. The TRV (thermostatics radiator valve) has lost communication with the CO10RF/UGE600 coordinator
- • Check or replace the batteries in the TRV
  • Check if the coordinator/gateway is connected to the power supply.
  • Force identification from the coordinator/gateway and determine if the devices are in the network.
  • Force a signal to heat from the regulator.
9. The adaptation of the TRV (thermostatics radiator valve) on the valve insert has failed
- • Check the TRV mounting on the thermostatic insert and reinstall the TRV.
  • Check the compatibility of theTRV with the thermostatic insert. If necessary, replace the thermostatic insert.
10. The RX10RF has lost communication with the controller
- • Check if the regulator is connected to the power supply.
  • Force identification from the coordinator/gateway and determine if the devices are in the network.
  • Force a signal to heat from the controller and check that the RX10RF is switched on.
