Need advice? More information?

The Secure Wall Thermostat and Receiver set is designed to control hot-water heating systems and floor heating installations. It includes the Secure Wall Thermostat, which can be installed in the room to be controlled and the Secure Boiler Receiver to operate the hot water boiler. The thermostat can be manually operated by the user or remotely operated via Z-Wave to set the desired temperature.

Wall Thermostat

The battery operated wall thermostat enables you to set the temperature of the room it is located in. When this temperature is reached, the thermostat instructs the Boiler Receiver (via Z-Wave) to switch the boiler on or off.

The unit’s LCD displays the target room temperature and by pressing the ‘temperature setting dial’ it will display the actual room temperature. It can also be operated using any Z-Wave remote or central controller.

Boiler Receiver

The Z-Wave controlled relay switch controls the water boiler and can operate loads of up to 3A. It includes manual On/Off buttons and LEDs to indicate the boiler's current state.

Take a look at this guide to see how easy it is to use the Secure Thermostat with the Vera Z-Wave controller.

Won't connect with controller and receiver at the same time
Won't connect with Z wave controller and receiver at the same time. Otherwise a straightforward wireless boiler controller without a timer.

A great improvement
Installed this to replace an old Honeywell radio thermostat. The only improvement I was looking for was Z-wave control. Total setup took me about 20 minutes, and it works fine with Veralite running UI7. It maintains a far more stable temperature than our previous system, notably increasing the comfort of our house. Struggling to see any downside, really, although the receiver box is a bit fiddly.

Works well, with minor niggles
This thermostat paired without a hitch with receiver, and seem to work quite well, TPI algorithm maintaining very stable temperature, while allowing boiler to condense more (by allowing radiators to cool between cycles). However there are several minor thing I've noticed: - It seem to have unreasonably short time for minimal "on" cycle. Since TPI for gas boiler assumes up to 6 cycles per hour (cycle every 10 mins), I've observed it sometimes switching boiler on literally for 10 seconds. This is too short, since boiler barely manages to start in this time, and instantly goes off. I understand this happens because it deems needed heat output very low, but I think it should just skip a cycle in this case. - Dust is getting between outer transparent plastic panel and LCD screen - When wall thermostat wakes up (or if you wake it up by pressing controls), it creates a very high-pitched ultrasonic noise (from DC-DC converter I assume). Luckily this lasts just for couple seconds

Secure Thermostat/Receiver Sets. Is it possible to use several sets independently?
RetiredBrian 12 Nov 2016
BEST ANSWER: I have two sets. They pair independently, but then I've decided to pair them instead to my Indego z-wave system and I control/read them from that. You can set and read the temperature and turn on/off the system from Indigo and I'd imagine this would be no different from other z-wave systems if you chose to do that.
Hi, Is the actuator capable of switching 220v load or it uses dry contacts to send signals to boiler ?

Hi, I am a bit confused whether I need the set for my Veraplus or just the actuator. If I buy the set then i will be able to send the commands to HRT4-ZW and then it will trasmit them to the actuator ?
dimi r. 18 Oct 2016
BEST ANSWER: This depends on what you're trying to achieve - if you just want to control the boiler on / off then the SSR303 boiler relay will work fine (as would any other Z-Wave relay). But if you want to be able to set a set-point temperature and have a thermostat manage the boiler to ensure that the temperature is maintained, then the set would suit you better. Take a look at the following guide for further information: http://www.vesternet.com/resources/scenarios/heating/boiler-radiator Hope that helps!
How do I know if this is compatible with my boiler? Do I need to check anything on my boiler?
Tuncay S. 26 Jul 2016
BEST ANSWER: We recommend wiring this at the boiler controller/timer - then you do not need to change any wiring with the boiler. These guides shows you how: http://www.vesternet.com/resources/application-notes/apnt-39 http://www.vesternet.com/resources/application-notes/apnt-20
