1.2.10 Electrical Heating
You can start electrical heating by sending text message #HEATING ON to the GSM subscription of
your HouseControl. You have to use your heater’s own control unit for selecting the desired temperature
and other settings before you can control heating remotely from your mobile phone. HouseControl will
reply to the issued command with text message O1:1 HEATING ON, and your home will warm up to the
temperature you selected from the heater’s control unit. If you repeat the same command twice, your
HouseControl will respond with O1:1! HEATING ON. The exclamation mark in the message means that
heating was already on.
You can switch heating off with command #HEATING OFF, which has the same effect as switching it off
directly from the heater’s control unit. The unit replies with text message O1:0 HEATING OFF.
Thermostatic Control
Thermostatic control is used for keeping indoor conditions at a constant temperature. To enable
thermostatic control, send command #THERMOSTAT ON to your HouseControl. Now you can adjust the
indoor temperature with command #TEMPERATURE XX. If you want to set the temperature below zero,
you have to insert a minus sign in the command, for example #TEMPERATURE -5. Thermostatic control
can be turned off with command #THERMOSTAT OFF. HouseControl reads the temperature value from
sensor T2, and starts or stops heating depending on the temperature.
You still have to set the maximum temperature from the heater’s own control unit as pointed out in
1.2.10. The maximum temperature is the upper limit that your HouseControl must comply with. If you
have set the maximum temperature to 21 degrees Celsius, HouseControl can have the temperature rise
up to 21 but not higher.

If you have enabled thermostatic control, you cannot use commands #HEATING ON and
#HEATING OFF.
1.2.11 Water, Air-conditioning, and Electricity
You can close the water mains valve and shut down air-conditioning with command #AWAY or #HEPAC
OFF. The difference between these two commands is that #AWAY does a bit more: not only does it
close the water mains valve and shut down air-conditioning, but it also shuts down yard lights and cuts
off electricity from the house. Command #HEPAC OFF only closes the water mains valve and air-
conditioning. Heating is not controlled with either of these commands although HEPAC stands for
