Professional humidity switch PLS1000
Relays T1 / T2 and F1 / F2 are switched off if the indoor sensor or outdoor
sensor is defective or not connected.

The parameters have the following functions:
TP_DIFF = TP1-TP2 (DEW-POINT-SPREAD)
The dew point spread determines at which difference between the dew point
TP1 and TP2 on, the relay T1 is to turn on.
Setting range: 2 to 10°C
Factory setting: 5°C
T1(MIN)
The minimum value for the internal temperature. The relay T1 or the connected
fan is switched off when the internal temperature has reached this value. This
will prevent unwanted cooling in the room.
Setting range: -40°C to +120°C
Factory setting: 10°C
REL T1 DELAY
With the help of REL T1 sets the switch-on delay for the relay T1.
This setting prevents frequent switching of the relay T1, with rapidly changing
dew point temperatures TP1 or TP2 and relatively small dew point difference.
Setting range: 0 to 60 sec.
Factory setting: 0 sec.
BEHAVIOR OF THE RELAY T1
Abbreviations:
T1 measured temperature at the indoor sensor
TP1 calculated dew point temperature at the indoor sensor
TP2 calculated dew point temperature at the outdoor sensor
dTP calculated difference TP1 – TP2
TP_Diff Setpoint for the difference TP1 – TP2
T1(min) Setpoint for the minimum permitted internal temperature
Relay T1 is switched on when
T1 ≥ T1 (min) and dTP ≥ TP_Diff
Relay is switched off when
T1 < T1 (min) or dTP ≤ 1°C
