ORT
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
