24. BOILER CONTROL

24.1.

Operating mode

The boiler control application monitors the boiler via SMS commands.
The boiler control can be used in three ways:
Temperature control mode
Program mode
Manual mode
A comfort temperature (T comfort) and energy savings temperature (T economy) can be set for the first
two modes.
The temperature is read by the NTC sensor. For MyALARM2 to correctly read room temperature, refer to
the installation recommendations in the next chapter.
24.1.

Tcomfort and Teconomy settings

The Comfort and economy temperatures can be set using the setup software or via SMS.
To set a new comfort temperature value (for example, 20°c), send an SMS with the following text:
SET HVAC.HC 20.0
To set a new economy temperature value (for example, 15°c), send an SMS with the following text:
SET HVAC.HE 15.0
Once a comfort or economy temperature has been defined, the application turns the boiler on/off via the
selected relay output. Entering a hysteresis value avoids too frequent switching on/off (it is advisable to set
a hysteresis value of at least 0.5°C).
