RET1000M/MS/MD combines a sleek modern design with a high performing energy saving control. The well-proportioned dial and clear temperature scale makes setting easy, including an easy to set upper and lower temperature limiting feature.

The RET1000M/MS/MD thermostat includes stylish backlit LED icons providing clear indication of power and output status.

As well as standard on/off control the user can select to benefit from Danfoss chronoproportional 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 off set normally associated with on/off or simple proportional control.

Chrono-proportional control significantly improves comfort and generally improves boiler efficiency by optimising water temperature.
