The controller is equipped with a semiconductor relay,
to which a load such as a pump, a valve etc. can be con-
nected:

The mains supply is to be carried out at the terminals:

The temperature sensors (S1 up to S4) are to be
connected to the following terminals with either polarity:
1 / 2 = Sensor 1 (e.g. Sensor collector)
3 / 4 = Sensor 2 (e.g. Sensor store)
5 / 6 = Sensor 3 (e.g. Sensor store top)
7 / 8 = Sensor 4 (e.g. Sensor return)
All Pt1000 temperature sensors are equipped with a
platinum measuring element in their tip. The electrical
resistance of the measuring element changes in relation to
the temperature (see table in chap. 5).
IP 20
The difference between FKP and FRP type sensors only
lies in the cable insulation material. The insulation material

of FKP type sensor cables resists a higher temperature, so

that FKP type sensors should be used as collector sensors.
FRP type sensors are best used as reference sensors in
stores or pipes.
The controller is equipped with a S-Bus for data transfer
