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.
