The room thermostat RDH100 from Siemens is an electronic room thermostat for heating, featuring a large, easy-to-read display and TPI control for precise temperature control in on/off heating systems.
It can be used in residential buildings, apartments, commercial spaces, or industrial buildings, in combination with zone valves, thermal valves, gas or oil burners, fans, and pumps, to maintain the selected room temperature.
Control with TPI (Time proportional integral) algorithm: the thermostat activates and deactivates the installation at regular intervals, which are determined by the relationship between the desired and actual temperature.
Large LCD screen: easy-to-read screen for ease of use and operation, with indications of desired or actual temperature.
The electronic thermostat RDH100 ensures the operation of the installation with maximum economy.
Operates with 2 AA 1.5V batteries.
Specifications are collected from official manufacturer websites. Please verify the specifications before proceeding with your final purchase. If you notice any problem you can report it here.
I have it for 2 years and I will have it for a long time, it is a great device, it has an accuracy of +/- 0.5 degrees.
As for those who say that the wheel breaks, if you treat it politely and not like a Neanderthal, it won't have any problems. Good and user-friendly product
The regulator breaks very easily. And as everyone writes, there is no replacement.
One year and something, Initially the regulator is not working properly while you increase it decreases, when you decrease it increases the temperature, at some point it synchronizes and with smooth movements it does what you want. It has some obviously energy saving program that works well, but in the big cold it flashes all the time, click, clack, click, clack every minute. Lately it doesn't give the command to the thermostat to close and the circulation continues, I realized it when the room temperature reached 25 degrees while it had an indication of closed circulation. Waste of money simply
Great expense! It detects temperature fluctuation +/- 0.5 !!! Great screen, reliable and accurate!
I have had it for 4 years without any problem, it works perfectly. I live in an apartment building and it saves me incredible amounts of money. One of the most useful purchases of such a product.
It has paid for itself tenfold.
Yes, it could have a light indicator, timers, etc. but you will have to choose the more expensive models for these functions.
Very easy to use.
The best there is so far. I have had it for 2 years and it hasn't had any issues. The room temperature is stable (without fluctuations, sometimes warm, sometimes cold) and the bodies are sometimes lukewarm, sometimes hot, etc. depending on the needs of the room. Essentially, it does internal compensation with the TPI program it has. What we as users need to understand is not whether the bodies are warm, but to achieve the goal - that is, the temperature we ask for. Anyone who is used to old analog thermostats and cannot understand how it works should not choose it.
Second time. It does not have lighting for the night, nor an indicator for the stop, and it operates at +/- 1.5.
As the others say. Thermostat with expiration date. 3rd year and the dial came off. Don't buy it.
The thermostat does not have any indicator light to show that it is on, and the screen is not illuminated, so you need to be mindful in general not to forget to keep it turned on.
The product is completely rubbish. Its sensor is internal. The box does not have grilles and the box needs to be heated for the internal sensor to capture room temperature, resulting in leaving the heater on for a long time. If you want to save on oil, stay away from this thermostat
The round switch that adjusts the temperature breaks extremely easily. From the first day of use, there was difficulty in adjusting the temperature. When you turn the switch, you realize that something is not functioning correctly. Within a few months, adjusting the temperature becomes difficult. Turning it to the right to increase the temperature actually decreases it. Very poor build quality. It shows at least a 3-degree temperature difference.
Money wasted. Zero stars. I got rid of it, threw it in the trash. I got an analog one and found a solution.
Stay away!
Every 2.5 years I change the thermostat, and I bought it again because I don't know much about electronics, so with one screw I install and remove it and it's ready. But every 2.5 years for such a company?
The RDH100 room thermostat is an electronic room thermostat for heating, featuring a large, easy-to-read screen and TPI control for precise control of room temperature in on/off heating systems.
The required temperature is adjusted using the rotary switch on the front of the thermostat, which provides:
TPI control algorithm (Time Proportional Integral): the thermostat activates and deactivates the installation at regular intervals, determined by the relationship between the desired and actual temperature.
Large LCD screen: easy-to-read screen for ease of use and operation, with indications of desired or actual temperature.
The RDH100 electronic thermostat ensures maximum efficiency of the installation.
I have it for 3 months.. it works fine and does what it says. It requires basic knowledge for the connection. If you set it to the comfort temperature mentioned in the instructions at 20 degrees. Read the instructions carefully for proper setup and use and any questions will be answered.
The thermostat is fine, the connection gave me a little trouble because I did what the previous ones said, but it kept tripping the safety switch. I connected it differently and it sparked, I almost burned it... Eventually, I reconnected it the way I initially did, raised the safety switch 2-3 times, and then everything was fine... Lx for power and L1 for return... If it doesn't spark, raise the safety switch a couple of times and it will be fine.
I have it for 3 years.
I have no issue with the wheel rotation that others mention it breaks.
It detects temperature variation +/- 0.5.
On the back side, it has a button from which you can select the operating mode setting, according to the MANUAL which you must search on the internet as it does not come with the device.
It is pre-set to PID SLOW program (Opening/closing every 4 minutes at least), which applies to heating systems with delayed response (e.g. oil boilers):
It also has programs:
- PID FAST (Opening/closing every 1 minute at least), for heating systems with fast response (e.g. gas boilers) but unsuitable for systems with slow response, because for example in the oil heating system it will cause damage to the solenoid valve due to continuous activation.
- 2 POSITION 1 K
- 2 POSITION 0.5 K.
MINUS 1 star for the lack of a backlit screen, obviously for energy saving reasons given that the device operates with batteries (with an indication in case replacement is required).
More reliable and accurate than a classic mechanical thermostat.
For garbage. I turn it on to operate and sometimes it doesn't make any contact. Money wasted on this wireless device, it doesn't do its job properly. Other times it reaches the temperature and continues to leave the bodies lit
It is very dark at night. You can't see anything. In order for the heater to not work, you have to lower the degrees manually.
The factory setting PID fast is indeed annoying and inadequate, it constantly flashes and many times, even when the temperature has dropped, it does not command the boiler to turn on. I will try the other three options and will come back. In setting 2R, 0.5K, it operates with greater accuracy and without constant flashing
If the temperature you want is about 2 degrees lower, it turns on and off by itself and it's good for saving energy, but the bodies remain lukewarm. (As soon as they try to warm up, you hear the relay and it shuts them off) Only if you set it 3-4 degrees higher, it warms them up. In the second year, the button broke for no reason and there is no replacement. So, it's a waste. I will not buy it again
I have it for a year. It does its job well, but sometimes it shows a different setting has been entered in the temperature... AND NOW LATELY IT GOT WORSE.. LOOK ELSEWHERE FOR SOMETHING BETTER.
Very good thermostat, I also have the wireless version of it in another house.
Both of them lack the illuminated screen, they have spoiled us :-)
Be careful with the electricians here who tell you what to connect where.. the wires of autonomy sometimes do not have the same colors in every installation. USUALLY (this means not always..) the black or even brown (phase) goes to Lx, the yellow or orange (return) goes to L1, the blue (neutral) is not connected ANYWHERE in this specific one because it is powered by its batteries and does not need additional power supply, L2 without connection in most applications.. it would be very correct to find the wires with a multimeter before connecting the thermostat and then it will be too late.
If you give a neutral to L1, you may immediately burn your new thermostat (its relay) and definitely the safety of the boiler panel
Easter came and the gas installation was finally done, and it worked for the first time. I came here to read reviews because I am ready to throw it away. Unfortunately, I can't upload a video here to show you what it does. Firstly, the knob often doesn't catch, you have to sit and play with it to make it work. Then, it opens and closes whenever it wants. It constantly makes a noise and lights up every three to five minutes, which is annoying. It stops before reaching the set temperature. The radiators burn even when they are closed. I mean, it lights up every five to ten minutes. Until now, I had two simple digital ones from the same company and I had no issues. You set the temperature, it reaches the temperature, end of story. It doesn't require rocket science or algorithms. I will talk to the company to see if it can be replaced because from the comments here, I learned that it has settings and such, and maybe I'll try a different brand and a new one.
After 2 years of use, the regulator broke and doesn't change. I will buy a new one and definitely not this one.
Negatively, I would say: it is not illuminated, which is not convenient.
And the relay is loud when it opens and closes
Wasted 40 euros on a thermostat that only turns on and off with a 0.5-degree difference, but it has exceeded 1.5 degrees and the gas boiler keeps working... it's a mess... I will buy from China for half the price and with wifi support to notify me without having to sit on top of it...
Only except that the power indicator is not easily visible.
I also found it important that it supports both PID and On/Off mode.
It works properly, it is beautiful, but everyone ends up with a broken rotary switch and functioning with a screwdriver. Unfortunately, a replacement was not found.
It is not illuminated, it has a power indicator. It can be adjusted to four different operating programs.
Within a month, the adjuster button broke. So I learned from the store that breakages are not covered by the warranty. Even so, there are no replacement buttons available, so it would be useless if it didn't eventually work with a toothpick.
The accuracy of 0.5 degrees results in the actual room temperature for the thermostat setting at 22.5 being 21.6 - 22.7.
I have chosen the setting "2R, 0.5K" as the default "PID Slow" was causing the thermostat to drive the electric valve crazy by forcing it to open and close at very short intervals.
Overall, I am not satisfied with the thermostat.
Whenever it wants, it turns on, whenever it wants, it turns off regardless of the desired temperature. Specifically, the thermostat indicates 22.5 degrees in the room, with a selected temperature of 21.5, and it had the gas open to burn.
The choice of 4 stars is not random, because it is very good, not perfect, but it does its job and more.
(1) good range of wireless communication with receiver on the boiler
(2) when set at 20°C, as soon as it drops to 19°C, it turns on until it reaches and exceeds the set degrees, so it doesn't turn on every now and then
(3) it is lightweight and easy to transport and place wherever it is convenient
The only negatives are perhaps the lack of decimals beyond 0.5, the lack of lighting on the screen, and the fact that there is no bright LED indicator for operation, although it has an arrow indicating that it is functioning on the screen.
For the money, it is definitely a good value for money. As for installation, if you don't know how, don't mess with it, let a professional do it, don't play with electricity ;)
