Thermostat control
Electronic thermostat for control of temperature by means of a sensor placed either externally in the floor or built into the thermostat. MCD4 can also operate in regulator mode (option). This is useful for renovation purposes where it is not possible to use a floor sensor.

Easy read-out of energy consumption
Total switch-on time in percent and calculated cost can be read out for the last 2 days, 30 days or 365 days. Overall energy consumption can thus be monitored.

Built-in clock – calendar with power backup
Comes with built-in 4-event program for automatic comfort and setback temperature. The clock and calendar have built-in battery backup, so the user never has to care about setting the clock after power interruption.

Graphical display
Unique user interface with new animated graphical menus and button based navigation for easy programming and readout of data.

Factory-set events
The thermostat is delivered with factory-set programs as detailed below:

• 4 events for 5 days and 2 events for days 6+7
• 4 events for 6 days and 2 events for day 7
• 4 events per day

Comfort mode
The room temperature can be temporarily changed for a single event. The comfort mode temperature is reset after a user selected number of hours. The thermostat will then return to the scheduled event program.
