Example:
TCW220, TST100, and appropriate heater are used to control the room temperature. The
wanted minimum temperature is 19°C. The initial temperature is 17°C.
TST100 is assigned to the first position for 1-Wire sensors.
For Relay1 local activation from Sensor1 is set.
Following parameters are set for Sensor1: Min=19, Max=100 and Hys=0.5.
When the controller is switched on, Relay1 is immediately activated because the monitored
temperature is out of range. This switches the heater on. The temperature is going higher.
When temperature reaches 19.5°C (19.0 + 0.5) it goes in range (trigger condition) and Relay1 is
deactivated. The heater is switched off.
The temperature falls and when it reached 19°C it goes out of range (trigger and alert
conditions). The relay is activated (heater is switched on) and e-mail is sent.
