Introduction
The thermostat is capable of switching on your heating system at pre determined times on different days of the week. It is possible to set 4 periods called
events each day with different temperatures. From factory a default schedule is programmed suitable for most installations. Unless you change these
settings the thermostat will operate to this default program.
Working with lower temperatures during times that the room is unoccupied will lower your energy costs without reducing the comfort. The thermostat has an
adaptive function that automatically changes the start time of a heating period so that the desired temperature is reached at the time that you set. After 3
days the adaptive function has learned when the heating must be switched on.
The thermostat type OCC2-1991-EKL has an external temperature sensor that is normally placed in the floor construction. In this configuration the
thermostat controls the temperature of the floor and not the temperature within the room.
Type OCC2-1999-EKL has a built-in temperature sensor. In this configuration the thermostat controls the temperature of the room, and the external
temperature sensor should not be installed.
Type OCD2-1999-EA has a built-in temperature sensor and an externally temperature sensor. In this configuration the thermostat controls the temperature
within the room and use the externally temperature sensor as limit sensor avoiding to high or to low temperatures in the floor construction.
The thermostat has a pin button marked R, allowing you to reset the thermostat to factory settings. These are listed at the end of this manual with space for
you to record your own weekly schedule.
The display is backlit when operating the buttons. The heating element is switched off when the light is on in the display.
The heating system can be switched off on the built-in interrupter. The Microprocessor taking care of the time will still be supplied with power whereby time
and day will be maintained. When the heating is required and the thermostat is switched on, it will continue the 4-event programme based on present time
and day.
