The Salus RT500RF is a sophisticated programmable room thermostat designed to provide precise control over your home's heating system. This device combines the functionalities of a traditional room thermostat and a heating controller into a single, user-friendly unit. Its primary purpose is to automatically switch your heating system on and off, maintaining a comfortable temperature according to a pre-set schedule. This intelligent control helps optimize energy consumption by ensuring heating is only active when needed, aligning with your daily routine.
One of the key distinguishing features of the RT500RF is its two-unit design, separating the operational functions for enhanced flexibility and performance. It comprises a Control Centre and a Receiver, which communicate wirelessly via a Radio Frequency (RF) signal. The Control Centre serves as the user interface, where you interact with the thermostat, set temperatures, and program schedules. It also houses the temperature sensing capabilities, ensuring accurate readings of your room's ambient conditions. The Receiver, on the other hand, handles the wiring connections to your heating system and directly controls the heat on/off function. This wireless communication allows for greater freedom in placing the Control Centre in an optimal location within your home, away from drafts or direct sunlight, without the constraints of wiring.
The RT500RF offers significant versatility in its programming options, catering to various lifestyle needs. Users can choose between a 5/2 day programming mode or a 7-day programming mode. The 5/2 day mode is the default setting, allowing for five distinct time and temperature settings for weekdays and separate settings for weekends. For those requiring more granular control, the 7-day mode enables five different time and temperature settings for each individual day of the week, totaling up to 35 separate program settings. This flexibility ensures that your heating schedule can be precisely tailored to match your weekly activities, maximizing comfort and energy efficiency.
Setting up the thermostat is designed to be straightforward, even for those new to programmable devices. The Control Centre features a large, easy-to-read Liquid Crystal Display (LCD) with a blue backlight, providing clear visibility of the current status, time, day of the week, and room temperature. The user interface is minimalist, with a few intuitive controls: UP, DOWN, BACKLIGHT/FROST, SELECT, SET, and RESET buttons. These controls allow you to navigate through settings, adjust temperatures, and confirm selections with ease. The device comes with built-in startup programming, offering a quick installation experience with factory default settings that are suitable for most users.
Beyond its core programming capabilities, the RT500RF includes several practical features to enhance user experience and protection. It offers a volt-free switching option, making it compatible with a wide range of heating applications, including both Volt Free and AC systems. Frost protection is a crucial feature, automatically setting the temperature to 5°C to prevent pipes from freezing during colder periods when the heating might otherwise be off. This mode can be activated or deactivated by simply pressing and holding the BACKLIGHT/FROST button.
The thermostat also provides a temporary override function, allowing you to momentarily adjust the set temperature without altering your programmed schedule. This is particularly useful if your plans change unexpectedly, and you need to boost or reduce the heating for a short period. The temporary override remains active until the next programmed time/temperature set point is reached, or until you manually cancel it.
For energy-conscious users, the RT500RF helps promote efficient heating habits. An energy-saving tip provided suggests finding the lowest comfortable temperature setting and maintaining it, as even a 1°C increase can lead to a significant rise in heating costs. The device also includes a "Burner on" symbol on the LCD, indicating when the heating system is actively calling for heat, providing clear feedback on its operation.
Maintenance of the Salus RT500RF is minimal, reflecting its robust design. The outer casing can be periodically wiped clean with a dry cloth; however, it's important to avoid using solvents, polishes, detergents, or abrasive cleaners, as these can damage the thermostat's finish. The unit contains no user-serviceable parts, meaning any servicing or repairs should be carried out by Salus Controls or their authorized agents to ensure proper functioning and to maintain the warranty.
The device continuously monitors its battery status and will display a low-battery warning indicator on the screen when the voltage drops to a certain level (around 2.6V). While the thermostat will continue to operate normally at this stage, it is recommended to replace the batteries as soon as possible to prevent any potential operational issues. The Control Centre operates on two AA alkaline batteries, and it's crucial not to use rechargeable batteries.
In situations where multiple RT500RF units are installed in close proximity, such as in neighboring homes or multi-zone heating systems, the RF address code setting feature helps prevent interference. Each Receiver can only respond to transmissions from a Control Centre with the same address code. This code can be adjusted on both the Control Centre and the Receiver using DIP switches and jumpers, ensuring reliable communication and preventing crosstalk between units. After changing these settings, a reset of the Control Centre is required.
A "Sleep Mode" is also available, allowing users to pause all thermostat functions to conserve battery power, with only the clock continuing to run in the background. This mode can be activated by pressing the UP and DOWN keys simultaneously and can be exited by pressing any key.
Overall, the Salus RT500RF is designed to be a reliable, flexible, and energy-efficient solution for managing your home's heating, offering both convenience and precise control through its intuitive interface and wireless capabilities.
