THERMOSTAT FUNCTIONS
Thermostat control:
Type OCC2 is an electronic on/off thermostat for control of temperature by means of a sensor either placed externally or built into the thermostat. The heat output is switched on and off with a difference of only 0.4°K.
Housing IP 21:
Can be mounted in bathrooms and other humid rooms. |

BUILT-IN CLOCK FUNCTION
OCC2 is with built-in 4-events program for automatic comfort and setback temperature.

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 OCC2 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.
Read-out of sensor temperature:
The actual temperature of the floor sensor can be read-out.
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 floor sensor:
Floor sensor is used for comfort heating of floor. The sensor is mounted in conduit of consideration of replacement. The conduit is mounted between heating cables and ended towards the floor surface. If required, the floor sensor can be extended up to 100 m with a standard installation cable.
Mounting of room sensor:
Room sensor is used for room heating. Thermostat with internal sensor is mounted approx. 1.6 m above the floor. Draught, direct sunlight or any other direct heating outlet must be avoided. If it is not possible to mount the thermostat in the correct position, remote room sensor type ETF-944/99-H is recommended. Type of thermostat incl. floor sensor is used, but a room sensor is mounted instead of floor sensor. |
