In a control loop with several room units, the temperature is measured in one device
only (the master). The LS flag (SL = 0) determines whether the room unit should
measure the temperature, or whether it is a slave device (SL = 1), in which case the
temperature sensor is disabled.
The default setting is SL = 0, i.e. temperature measurement active.
Further control loops can also be defined by means of a special application in the room
controller. In such cases, other room units can measure the temperature on the same
room bus.
The error in an NTC 10 kΩ room sensor error combined with a measurement error
results in an error in the measured temperature reading. This can be corrected by
setting an offset correction value.
This menu displays the current measured temperature including the previously set
offset correction value.
The LCD display contrast can be adjusted in this menu to suit different lighting
conditions.
To measure the temperature with the built-in temperature sensor, the HTC3.2/.. room
operator unit must be installed in a location suitable for room temperature
measurement.
This restriction does not apply if the temperature is measured with an external
temperature sensor. A suitable temperature sensor for this unit is the HSE1.1 cable
temperature sensor. If the VIMAR idea installation system is used, the room
temperature sensor HSE1.2 is also suitable.
Heat sources result in false temperature measurements. Ensure a minimum distance of
1.5 m from lamps.
