User Instructions

Setting Dial Danföld 20°C

Unlike normal room thermostats, the ORT-10 varies the heat output of the Opentherm condensing boiler to which it is connected. This adds to the boiler efficiency significantly by ensuring that the boiler keeps in economical condensing mode whenever possible.

Daily use is as easy as setting

the thermostat dial to the required setting, the advanced electronics and software within the thermostat establish two-way communication with the Opentherm boiler to ensure optimal operation.

In addition to the room temperature control, the ORT-10 also incorporates a feature which, dependant on boiler type, allows the domestic hot water store in the boiler to be kept hot or to be turned off, for example when on holiday. To select hot water and heating off, simply turn the thermostat dial to the holiday position

or press the button if you still wish to control the central heating only.

Settings

button: Pressing this switches off the boilers HW store*. Unit will display to confirm.

*(This feature is dependant upon boiler type).

Indication

Start-Up: When boiler is first turned on the LCD will flash for 20 seconds.

Normal Operation: Flame symbol will be displayed whenever the boiler is fi ring. The bars to the right of the displayed temperature visually indicate the level of modulation at the boiler. 1 bar =25%, 2 bars = 50% etc.

Holiday Mode: When thermostat is put into, or taken out of holiday setting the LCD will flash for 20 seconds.

Alarm Mode: Should a fault occur with the boiler the LCD will display Er (or Er + associated error code if boiler functions support) to warn of failure. For details of errors codes please consult your boiler manual.
