Provides excellent comfort consistently.
Ultra-durable and reliable thermostat.

Main Highlights

SAVE UP TO 40% ON YOUR HEATING BILL: The installation of a room thermostat and radiator thermostats can reduce energy bills by as much as 40%. Tests carried out at the University of Salford in their Energy House facility showed that the costs of running a heating system with a full set of temperature controls was 40% less than the same system operated with only a timer. The tests also showed that individual room temperature controls (TRVs) were necessary for the system to maintain balanced temperatures around the house. If you are about to change your boiler or if you have old radiator thermostats it is really important to install new heating controls and radiator thermostats.
EXCELLENT COMFORT: The RAS-C2 6005 provides excellent comfort. So if you are struggling with cold radiators and want to improve the comfort RAS-C2 6005 is an excellent choice. It reacts twice as fast to a 1 degree change in room temperature compared to cheaper wax filled radiator thermostats on the market, which also makes it a great choice for radiators in your private home
DURABLE RADIATOR THERMOSTAT THAT LASTS - With simple maintenance, Danfoss thermostatic radiator thermostats will function flawlessly for many years. Danfoss comply with the highest quality standards in the market. Our Sensors are produced in Denmark using a highly automated production process that prevents faulty products
ROBUST CONSTRUCTION - This Danfoss RAS-C2 Thermostat combi pack construction is particularly robust, with a Revolver mechanism correcting water flow within valve in situations of reverse flow. Our Danfoss RAS-C2 Thermostat was approved to European standard EN215 and manufactured under ISO9002 quality systems being substantially above the requirements of the European Standard EN 215
EASY TO USE FEATURES - The Danfoss Thermostatic Sensors RAS-C2 combi pack heating thermostat controller has a frost protection factory pre-set programme. Danfoss is the world’s leading supplier of radiator thermostats and well known for high-quality products that are easy to install.
