Professional humidity switch PLS1000
9. EXAMPLES OF USE/SETTINGS
Example 1: A fan heater is intended to warm the room temperature to 25 °C.
If the room temperature falls below 23 ° C, the fan heater should switch on
and heat the room to the designated temperature.
SETTINGS ON THE TLF1000:
T set = 25.0 ° C, switch-on difference T-Diff heating = 2.0 ° C. As soon as
the temperature drops by 2 ° C (to 23 ° C), the fan (REL „H“) switches on and
switches off again when it reaches ≥ 25 ° C.
Example 2: When a temperature of 45 ° C and a humidity of 75% is
reached in a greenhouse, either the skylights should open or fan be switched
on. When the temp. Drops to 35 ° C (switch-on difference T-Diff cooling =
10.0 ° C) and the humidity drops to <60%, the fan should switch off and the
skylight should close.
SETTINGS ON THE TLF1000:
T set = 45.0 ° C, (Rel. Switches on at a temperature of 45 ° C) Switch-on differ-
ence T-Diff Cooling = 10.0 ° C (REL „K“). As soon as the temperature drops by
10 ° C (≤ 35 ° C), Rel „K“ switches off.
F SET = 75%, (Rel. Turns on at 75% humidity) F-Diff Del. = 15%. As soon as the
humidity drops to 60%, relay „E“ switches off.
If both relay contacts „K“ and „E“ are connected in series, the fan
does not switch on until both criteria (temperature and humidity) are met. The fan
is switched off when a criterion is reached.
If the relay contacts (normally open) are switched in parallel, the fan
runs as long as one of the criteria is met.
