Room sensor RASPT
Operation mode: The room sensor RASPT is a special
development of „Technische Alternative” and is provided for
installing in living rooms (reference room). It should not be
installed near to a heating source or to a window.
It is possible to change the room temperature in heating
mode in a range of approx. +/- 4°C and to select between
several modes (automatic, normal, lowered and frost protec-
tion mode).
Connection: The RASPT has to be connected to the termi-
nal position T6 and sensor mass (ground).
Setting: Operating with controller HZR65 the room sensor
must be defined as parameter “
rAS
” in automatic mode. Only
in this case the controller detects the values of the sensor.
Frost protection conditions for heating circuit
The frost protection limit is set in mode “
Stb
” (Standby) as parameter.
