10.9. Wiring of probes and sensors
10.9.1. RTS [room temperature sensor] & OTS [outdoor temperature
sensor]
Two wires are required. Colour and pole correctness are not important for temperature-dependent
resistors [NTC].
There are 3 clamping units in the temperature sensor, but only 2 clamping units need to be connected
to the control at any one time, see circuit diagram below. The circuit diagram is also stuck to the inside
of the cover of each temperature sensor.
Clamping unit 1 + C = OTS is used for the new SchwankControl
Clamping unit 2 + C = OTS is used for the old ThermoControl
Outdoor temperature sensor OTS for switch-on
optimisation.
Part number: 40652081
Measuring element: 2 x NTC sensor connected in series
Protection class: IP 54,
Pin "1" and "C" for SchwankControl Touch
Pin "2" and "C" for ThermoControl Plus M
