Sensor type
Solar collectors reach standstill temperatures of 200 to 300°C. No value above 200°C is
expected due to the sensor installation point and physical properties (dry steam does not
conduct heat well, for instance). The standard PT1000 series sensors can be permanently
exposed to 240°C and briefly to 260°C. KTY sensors are designed for brief use at 180°C.
The
SENSOR menu enables changing over of the individual sensor inputs between PT1000
and KTY types.
As default factory setting all inputs are set to PT1000 type.
PT, KTY Temperature sensors
GBS Radiant sensor (can be used for the start function and solar priority function)
S6 25 Fixed value: e.g. 25°C (using this settable value instead off measured
temperature)
Setting range: -20 to 149°C in increments of 1°C
S6 S1 (Transfer of values) Example: Instead of a measured value the input S6
receives its (temperature) information from input
S1. A mutual allocation (in this
example also:
S1 S6) in order to link information is not admissible.
In addition it is possible to assign values from external sensors (E1 to E9).
DIG Digital input: such as when a volume flow switch is used.
Input short-circuited: Display: D1
Input interrupted: Display: D0
OFF The sensor is not displayed on the main level. The sensor value is set to 0°C.
VSG Volume flow encoder: Only sensor S6 to read-in the pulses from a volume
flow encoder
LPP Litres per pulse = the volume flow encoder’s pulse rate (only when sensor type
S6 = VSG). (ex works = 0.5)
Setting range: 0.0 to 10.0 litres/pulse in increments of 0.1 litre/pulse
WS Wind sensor: Only connected to input S6, to read in the pulses of the wind
sensor
WIS01 from Technische Alternative (1Hz per 20km/h).
