Danfoss RET2000B-RF+RX1S Digital Room Thermostat and Single Channel Receiver

RRP: £121

RET2000 Digital Room Thermostats combine sleek modern design with high performing energy saving control. Incorporating a generous, easy to read display that clearly shows the room temperature and output status of the thermostat. Further enhanced by an inbuilt backlight this thermostat is also ideal for those with poorer eyesight or where the location is dimly lit. As well as standard on/off control the user can select to benefit from Danfoss chrono- proportional control. Normally set at installation although easy to change via a DIP switch this micro-processor based control system will deliver increased comfort and improved economy.

When chrono-proportional mode is set, the thermostat introduces a fixed cycle rate on the system and then determines the duration of the On and Off periods within each cycle in proportion to load. The control algorithm used to determine the on/off periods uses a proportional + integral (PI) routine to eliminate offset normally associated with on/off or simple proportional control. Chrono-proportional control significantly improves comfort and generally improves boiler efficiency by optimising water temperature. Additional features include settable upper and lower temperature limits as well as pushbutton lock to avoid tampering. If preferred the temperature display can also be set to show o F. The RET2000 also has the option to be set as a cooling device, reversing the output logic and including compressor delay settings.
