- Modern stylish design
- Intelligent heating control for increased fuel economy
- Micro-processor accuracy
- Setting dial with LCD temperature display
- Low profile mounted style
- LED power and output indicator
Unique in the Danfoss range of thermostats, the low-profile, flush mounted design of the FMT230D blends in seamlessly with existing electrical fittings such as light switches and electrical outlets. Fitted into a standard single gang UK electrical accessory box, the thermostat has an installed profile of just 16mm.
This newly designed flush thermostat combines the ease of use benefits of an easy to set dial, with a simple to read LCD display to provide accurate temperature control in all situations. The LCD display, that normally shows current room temperature, momentarily changes to show the required set temperature whenever the dial is turned. An LED light to indicate power supply, and another LED light to indicate when the output is active makes checking whether
the heating is on straight forward. A simple indication of either a flame, or a snowflake* on the LCD provides visual confirmation of which operating mode as been selected.
The FMT230D allows selection of traditional on/off control, or advanced chono-proportional control. By using the chrono-proportional control method, compared to standard electronic on/off control, energy and carbon emission savings of over 10% are achievable.
Options for setting up the thermostat are selected at time of installation by easy to set switches on the rear of the unit allowing selection of heating/cooling modes, on/off or chono-proportional control and 3/6/9/12 cycles for chono-proportional control.
* If cooling mode has been selected |

- 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-01 is a sophisticated room thermostat which provides modulating control of OpenTherm equipped condensing gas boilers.
Unlike traditional thermostats, the ORT-01 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 a status LED indicator that provides information on boiler output and a common alarm indication which is lit whenever a fault is encountered within the boiler. |

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. |

- Modern stylish design
- Battery driven, electronic accuracy
- Large, easy to use setting dial
- LCD displays set temperature and actual temperature
- Wallplate contruction for ease of installation
RET-B is a battery powered room thermostat that offers the advantage of an easy to use setting dial plus the convenience of an LCD to display temperature. It is an ideal product in the upgrade and replacement market since it only requires a two-wire connection.
Styled upon the RMT and RET room thermostat ranges, RET-B provides accurate electronic temperature control without the need for an external power supply. The design utilises a micro-processor which, as well as providing accurate temperature control, also drives a small LCD display which, during normal operation, displays actual room temperature and which changes briefly, to show setting temperature, whenever the setting knob is moved.
The micro-processor design also brings with it many sophisticated functions not normally found within such a thermostat. These include optional chrono-proportional regulation and cycle rate adjustment, heat or cool operation, compressor delay timer if cooling operation is selected and Fahrenheit or Centigrade temperature scale. |

The LCD display, that normally shows actual room temperature, changes momentarily to show set temperature whenever the setting dial is moved. Styled upon the RET room thermostat, the RET-MD can be set up by the installer to provide either traditional on/off control or more sophisticated chrono-proportional control for increased comfort and economy.
The RET-MD is an intelligent room thermostat that incorporates an energy saving delay start feature, which delays the start-up of the heating dependent upon how close to set-point the room temperature is at the time the central heating time switch is scheduled to turn on the heating system. Under most load conditions, this feature reduces the number of hours per day that the system runs, without creating any discomfort. This feature can, if necessary, be cancelled if the user wishes to override the delay period.
The RET MD is ideal for use with combination boilers and can be installed without the need for complicated wiring or commissioning. |
