Description of the boiler
The Rinnai Q boiler is a room sealed, condensing and modulating central heating boiler. The Q175C has an integrated domestic hot water feature.
The boiler is provided with a integrated control system. Because an outdoor sensor is connected to the boiler, the boiler works weather dependantly. This means that the boiler control measures the outside temperature and flow temperature. With this data the boiler calculates the optimal flow temperature for the installation.
When the boiler is connected to an RS100 room thermostat information can be retrieved from the boiler. For more information about the Rinnai thermostats. Please refer to the user manuals.
RS100 |
On the bottom left side of the front panel there is a |
|
|
|
small door. Through the transparent panel you can |
|
see the boiler status on the display. After opening |
|
this door you will find the function buttons. |
