Electric Thermostats

ORT-10



- Provides full modulation to OpenTherm equipped boilers
- Simple to install 2-wire non-polarised low voltage communications
- Accurate PI room temperature regulation
- Significantly improves boiler efficiency
- Dial setting provides easy to understand user interface


The ORT-10 is a sophisticated room thermostat which provides modulating control of OpenTherm equipped condensing gas boilers.

Unlike traditional thermostats, the ORT-10 exchanges data with the boiler it controls as opposed to simple on/off commands. This type of control, in addition to providing closer, more accurate room temperature control, also ensures that the flow temperature from the boiler is modulated down to as low a level as prevailing load permits, thus significantly increasing the proportion of the boiler operating time that is spent in economic condensing mode.

The thermostat is fully compliant with the OpenTherm communications protocol including low load regulation and domestic hot water “keep hot” feature now in common use in many combination boilers.

The thermostat utilises a micro processor which provides the accurate PI control algorithm and manages the bi-directional data communication with the boiler.

User interface is by means of an easy to understand setting dial and an LCD display that shows ambient temperatures, provides information on boiler output and a common alarm indication which is lit whenever a fault is encountered within the boiler.

The ORT-10 incorporates two additional energy saving features. Selecting the suitcase on the dial, allows the user to select an 8°C heating setback temperature and turns the hot water store in the boiler off. The tap button switches off the hot water store within the boiler, but maintains the central heating temperature as its setpoint.
