ITEM-NO. 04.12.0005.1 / EAN-CODE 4010940041472

feeling D201 OT

PRODUCT DESCRIPTION

The feeling D201 OT is a digital, programmable room thermostat with OpenTherm interface. The modulating control enables fast, need-based and energy-saving individual room control and flow optimisation, and to domestic water heating with Legionella protection. The high control accuracy also enables efficient utilisation of the plant. The Chronostat has various operating modes, which allow a comfortable indoor climate according to the individual needs. With the large, backlit display, user- friendly programming and operation is ensured, even in low light conditions. The display of the system operating hours enables monitoring of energy consumption and helps save energy. To increase the energy balance, the feeling D201 OT has external inputs that, for example, can realise the weather-dependent control system with an outdoor temperature sensor. The feeling D201 OT stands for simple and modern design and can therefore be optimally integrated into the interior design.

ErP Description
An electronic room thermostat that varies the flow temperature of the water leaving the heater dependent upon measured room temperature deviation from room thermostat set point. Control is achieved by modulating the output of the heater.
 
A heater flow temperature control that varies the flow temperature of water leaving the heater dependent upon prevailing outside temperature and selected weather compensation curve. A room temperature sensor monitors room temperature and adjusts the compensation curve parallel displacement to improve room comfort. Control is achieved by modulating the output of the heater.
