In this article, I present the Honeywell HR30 Comfort+, which does not have a Smart Home connection but is still one of the best electronic radiator controllers from Honeywell. This article is part of the series “Electronic radiator thermostats in review”, in which I test and evaluate electronic radiator thermostats from various manufacturers.

Scope of delivery
The Honeywell HR30 Comfort+ comes with an M30 x 1.5 attachment that fits all M30 x 1.5 radiator valves from Honeywell, Braukmann, MNG, Heimeier, Danfoss and Oventrop sold today. In addition, there is an adapter set for old Danfoss valves in the packaging. Furthermore, a display cover for adjusting the display position is included in the scope of delivery.
Unfortunately, the relatively high price does not include batteries. You should order a pack of good AA Batteries*. I cannot recommend rechargeable AA batteries for electronic radiator thermostat.
Installing the radiator thermostat
The installation for the HR30 was very simple. First, remove the old radiator thermostat and attach the supplied M30 x 1.5 valve attachment to the radiator valve (see figure 3).
Then two AA batteries are inserted into the HR30 radiator controller. The radiator controller is then placed on the valve attachment and can be snapped into place. After successful engagement, the HR30 Comfort+ is ready for operation (see figure 4).
Programmierung
The first “WOW” effect occurs when you notice that the large display is illuminated. For reading the temperatures and setting the times as well as for programming, the illuminated display is a real advantage in dark corners.
First you can select a language, then the date and time are requested and programmed into the HR30. Afterwards, you can start programming the heating times. Unfortunately, I found the programming of the HR30 not really intuitive at the beginning and had to take a look at the manual. However, if you follow the steps in the manual, the setting is no problem.
What I particularly like about the programming is that you can set individual values for each day of the week. In addition, there is the possibility of a party and vacation program as well as a special use. The HR30 is delivered with three preset time programs for heating and economy mode, but I think they should be customized.
Usability
A controller ensures that you can easily set the temperature on a dial. If you are too cold or too warm, you can adjust the temperature at any time, just like with a conventional thermostat. If you also want to save energy, you can do so via the so-called “ECO mode” and the optimization function.
Control behavior
The Honeywell HR30 Comfort+ regulates the room temperature very precisely and reliably ensures a constant temperature. The HR30 has the function “window open detection”, which is to ensure that the thermostat closes automatically during ventilation.
After several tests, I can say that this function is not quite mature, because the thermostat reacted to a cold air drop only after about 2 – 3 minutes during a shock ventilation. For a shock ventilation, which should not last longer than 3 – 5 minutes in the cold season, this reaction time is too long in my opinion.
Update 18.03.2015: I have again studied the operating instructions of the Honeywell HR30 more intensively and saw that one can adjust the sensitivity of the window function at falling and at rising temperature. Furthermore, one has the possibility to set the duration of the window function:
“Duration of window function” (basic program 5)
- Setting 0: Window function not active
- Setting 30 minutes to 90 minutes – valve opens after the stored time
“Sensitivity of the window function when the room temperature drops” (basic program 6)
- Sensitivity level 0.5 very sensitive
- Sensitivity level 3.0 little sensitive
- Factory setting: 0.8
“Sensitivity of the window function when the room temperature rises” (basic program 7).
- Sensitivity level 0.1 very sensitive
- Sensitivity level 3.0 little sensitive
- Factory setting: 0.3
Here it is possible to define different settings for the window function. Radiators that are far away from the window can, for instance, be given a very high sensitivity, radiators that are close to the window can be given a moderate sensitivity. If you want to do without the window function completely, you should nevertheless read the following tip.
Tip: If you want to save on ventilation, you should manually turn the thermostat to a low temperature during shock ventilation and then switch back to automatic mode. During tilt ventilation, the “window open detection” does a good job.
Conclusion
The design of the HR30 is decidedly exclusive and anyone who values a good-looking programmable radiator thermostat with many functions should strike here. A great bonus is the large illuminated display, which you only learn to appreciate in comparison with other radiator thermostats. Unfortunately, the “window open detection” is still a bit immature, but almost all electronic radiator thermostats have to deal with this problem.
In my update from 18.03.2015 I pointed out the setting of the sensitivity of the window function. After several tests, this also worked a little better. Understandably, the “window open detection” cannot keep up with the speed of a window contact.
Rating: Honeywell HR30 Comfort+
Other manufacturers have shown more sensitivity for the customer when it comes to the batteries and included one pack in the scope of delivery. With two batteries in the box, the HR30 would have earned the 5 stars. So if you decide to buy the Honeywell HR30 Comfort+, order a set of AA-Batteries* at the same time.
Summary
ADVANTAGES: design, illuminated display, optimization function, window open function
DISADVANTAGES: price, delivery without batteries, control volume
