This guide shows how to control a Z-Wave-based heating system using the Fibaro Home Center 2 controller.
The aim of this project is use the Home Center 2's (HC2) 'Heating Panel' to control a boiler-based heating system:
For this project I used a Z-Wave home automation system comprising of:
The Secure Wall Thermostat and Secure Boiler Receiver were chosen as they are easy to install and work well as a directly 'associated' pair. Other thermostats or relays can be used as well. The Fibaro Home Center 2 (HC2) controller is used for configuration and set-up, after which we use its 'Heating Panel' to control the heating schedule and change the thermostat's setpoint temperature at predefined times of the day.
In a traditional heating system the heating is only active during predefined periods of the day, and the temperature is determined by the setpoint on the thermostat. In HC2, we will use the 'Heating Panel' to change the thermostat's setpoint at different times of the day. This also has the advantage that you can set different temperatures for different times during the day rather than simply having it On or Off.
The time and temperature scheme I chose for this project is shown in figure 1.
Figure 1 - Heating Schedules and setpoint temperatures
We will create this schedule within HC's 'Heating Panel', this will then change the thermostat's setpoint at predefined times through the day.
To implement this heating system it's important that HC2 is configured as follows:
For further information, take a look at Application Note 20 - Adding and Configuring the Secure Thermostat and Receiver and Application Note 19 - Associating Devices in Z-Wave Controllers.
Before we can use the thermostat to control the heating we need to allocate it to a HC2 room and set it as that room's thermostat.
The heating schedule will be created and controlled from the HC2 Heating Panel.
Now you have complete control of your heating system from the Fibaro Home Center 2 or directly from the thermostat.
