Thermostat control

Electronic thermostat for control of temperature by means of a sensor placed either externally in the floor or built into the thermostat. OCD4 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 a built-in 4- or 6-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.
