THERMOSTAT FUNCTIONS

Thermostat control: 
Type OCD2 is an electronic on/off thermostat for control of room temperature by means of a NTC sensor. The heat output is switched on and off with a difference of only 0.4°K.

Temperature limitation:
OCD2 is with a floor sensor that can be used for one of the following:
- Min. temperature limitation
- Max. temperature limitation.
- Min. and max. temperature limitation
Using limitation sensor provides optimal comfort temperature and avoid too high temperatures destroying the floor construction.

Housing IP 21:
Can be mounted in bathrooms and other humid rooms.

BUILT-IN CLOCK FUNCTION
OCD2 is with built-in 4-events program for automatic comfort and setback temperature.

Factory-set of events:
The OCD2 thermostat is delivered with factoryset programs as follows:

Day 1-5
Event	Time	Temperature	w/ air sensor
1	06:00-08:00	Comfort	20°C
2	08:00-16:00	Setback	15°C
3	16:00-22:30	Comfort	22°C
4	22:30-06:00	Setback	15°C
Day 6-7
Event	Time	temperature	w/ air sensor
1	08:00-23:00	Comfort	22°C
4	23:00-08:00	Setback	15°C

Individual programming of events:
The factory-set periods and/or temperatures can be deleted or changed according to requirement. Furthermore, the following programs can be selected:
- 4 events 6 days and 2 events day 7
- 4 events per day
OCD2 is with adaptive function meaning the thermostat calculates when the heating has to be switched on to make sure that the comfort temperature is obtained at the required time.

Comfort mode:
The temperature can be temporarily changed for a single event. The comfort mode temperature is reset at the next event, and the thermostat will return to the scheduled event program.

Manual mode: 
The scheduled event program can be cancelled e.g. during holidays, instead the temperature can be adjusted to e.g. 5°C for frost protection. The new setpoint is valid until the manual mode is cancelled.

Monitoring of energy consumption:
Total switch-on time in percentage can be read-out within the latest 2 days, 30 days or 365 days. In this way the heat consumption can be controlled.

Backup function:
All settings and the clock are maintained in case the thermostat is switched off on the built-in interrupter. In case the main power supply is interrupted for more than 50 hours the current time and date must be reset. In power term installations with daily disconnection of the main power to the heating installation, it is recommended to connect the thermostat to the primary line that is not disconnected, and connect the heating installation over an external relay.

Changing of type:
The thermostat can via the software menu be modified to one of following thermostats:
Type               Product
OCC2-1991H1 Clock thermostat incl. floor sensor 3 m
OCC2-1999H1 Clock thermstat with built-in room sensor
At factory reset the thermostat will for security reasons return to an OCD2 type. In case the limitation sensor has been removed it will generate a failure code “E2”.

CE Marking: 
The thermostat meets the requirements of the following standards:
EMC directive: EN61000-6-1:2001, EN61000-6-3:2001
Low voltage directive: EN60730-1, EN60730-2-9

MOUNTING
Mounting of the thermostat:
1. Flush mounting in standard wall socket.
2. In combination with light switch types Busch-Jaeger, Merten, Ensto, and Eljo. Relevant type double frame is used.
3. Surface wall mounting with baseplate type OTN-VH.

Mounting of room sensor: 
The room sensor is used for room heating. The thermostat with built-in sensor is mounted approx. 1.6 m above the floor. Draught, direct sunlight or any other direct heating outlet must be avoided

Mounting of limitation sensor: 
Max. temperature limitation is used for protection of installation or construction against excessive temperature. The sensor is mounted at a place where excessive temperature may arise. Min. temperature is used for better heating comfort.

The sensor is mounted as floor sensor. The sensor is mounted in conduit for replacement purposes. The conduit is ended towards the floor surface. If required, the sensor cable may be extended up to 100 m with standard installation cable.
