Technical Information
Room transmitter without timer
Room transmitter designs come with or without operating mode switches. They are electronic fuzzy controllers with integrated sensors.
The temperature range can be adjusted between 5°C and 30°C.
The room transmitter version with operating mode switch enables you to select day, set-back or automatic mode, or to switch off. In automatic mode, a time-dependent room temperature reduction (approx. 4 K) is activated by a timer integrated into the central unit.
Room transmitter with digital timer
The room transmitter with digital timer offers 4-key menu operation. The display shows actual room temperature, time, and operating conditions. There is a built-in real-time clock with automatic summer/winter time settings that can be programmed for weekly or daily schedules. Three time programs can be preset and changed if desired.
The temperature range can be set between 5°C and 32°C.
Through the self-learning heating curve the set temperature is reached at the selected time.
Central unit
The following versions are available:
– with 6 output channels
– with 8 output channels and timer.
The cover over the timer can be removed for setting the timer. The display is backlit during mains operation and includes field-strength display and child protection.
The integrated antenna in the central unit receives the radio signals from the room transmitters. Thermal actuators can be connected to the output channels. The room transmitters can be assigned to one or, in the case of the version featuring 8 output channels, several output channels.
An LED is assigned to each output channel to act as an operational status indicator.
