For controlling heating installations via temp. T or differential temp. T.
Connections for 3 temperature detectors: T-flowpipe, T-return, T-outside The temp. board can be logged on
and off in menu 2.12.
6 a KTY10 temp. probe (-20 ºC to 140 ºC) is only suitable for T
6 b Pt100 temp. probe (0 ºC to 140 ºC) is also suitable for T < 10° Kelvin.
The temperature board permits the use of the following control modes:
Controller: T, p-c = f(Ta) (only positive control direction)
Regulator: n = f(Ta), n = f(Tp), n = f(Tvl), n = f(Trl)
The measuring range of the temp. board is from -20 °C to 140 °C.
A defect in the probe occurs at < -27 °C (short-circuit) or > 152 °C (break).
