Term Description
Analogue set
temperature 20 mA
Setting up upper limit of analogue set temperature at 20

temperature Max.
Setting up maximum analogue
Analogue must

Setting up minimum analogue set temperature
Line monitoring Activates the line monitoring (ON/OFF)
Barrier times
Time 1
Two different time options are available:
time 1:
time 2:
08:00 – 11:00
Setting up individual hot water tank loading times of every weekday,
when it will be not heated.
Monday preset gets assigned to remaining weekdays
External requirement at digital input:
At a digital request the external set temperature gets transmitted as value to the heat supplier.
External requirement at analogue input:
At an analogue request a calculated (= linearly interpolated) temperature gets transmitted to the heat
supplier.For an understanding, figure
„analogue set temperature 4 mA“ and „analogue set temperature 20 mA“.
The line in the diagram results from t
figure 7. 20: External demand
For example at an analogue request with an current signal of 12 mA, a temperature of 35 °C is registered at
the heat supplier, provided that the digital requirement (= external must temperature) is not higher.
