Disabling the Room Thermostat via the Combi Boiler Control Unit
8.6. DISABLING RecoWa COMBI BOILER CONTROL UNIT
When the Smart Room thermostat system is installed, the buttons and keys on the control
panel of your combi boiler are disabled and non-functional, the combi boiler is fully
controlled by Recowa mobile phone application.
When you want to disable (cancel) the smart room thermostat system for any reason
(such as the failure of the Combi Boiler Control Unit, or being out of order due to physical
damage) and control the combi boiler using its buttons and keys on its panel, this can be
done in two ways:
1. Plug off the electrical power supply of the Combi Boiler Control Unit from the socket
(Figure 20-1).
2. Bring the switch on the right side of the Combi Boiler Control Unit upwards to position
(B) (Figure 20-2).
- Disconnect the power supply to the boiler (if it is a plug-in connection, remove the
plug from the socket) and wait 5 seconds and insert the plug to the socket again.
- If the power supply of your boiler is directly connected to the fuse, switch off the fuse
(V-Automat switch) and switch on the fuse again after waiting 5 seconds (Figure 20-3).
- You can now control the combi boiler using its control panel, as the Recowa unit is
completely disabled.
If the electrical power supply of the Combi Boiler Control Unit is supplied
directly by the V-Automat switch, you must inform our Authorized Service
in order to stop the connection and do not perform any operation yourself!
NOTE:
After the repair of the Combi Boiler Control Unit, the installation should be made
by our Authorized Service to be able to control your boiler again via the thermostat.
This switch on the device is at position (A) as a factory setting.
Position A:
Thermostat control is enabled.
Position B:
Thermostat control is disabled.
