Danfoss Room Thermostats

Danfoss room thermostats measure the room temperature and switch a boiler, or the thermal actuators of underfloor heating circuits, on and off accordingly. This page brings together Danfoss digital and programmable thermostats, wireless (RF) sets and the Icon, Icon2 and Basic Plus 2 series for underfloor heating zone control.

For single-zone apartments RET 2001 and TP 5001 are the usual choice; for underfloor heating projects where every room is controlled separately, Icon and Icon2 stand out.

How to choose a Danfoss room thermostat

Answer three questions: what will the thermostat control (a boiler or thermal actuators), will it run on batteries or 230 V, and can a cable be run to the wall or is a wireless set needed?

See all brands in the room thermostats category and the master controllers in zone control and thermostats. Popular items: the RET 2001 B battery digital thermostat and the Icon programmable room thermostat. More products on the Danfoss brand page.

All products are original and supplied with an invoice; the warranty is provided by the manufacturer or importer. The current price is shown on each product card: the VAT-inclusive price first, the VAT-exclusive price below it.
