INSTALLING THE SENSORS
Depending on the hydraulic system installed, corresponding sensors
must be installed and connected.
See the hydraulic plan and the circuit diagram for the plug
connections and the necessary sensors for your particular hydraulic
system.
✎ The available hydraulic systems can be found in section “4.10 HDG
hydraulic systems” in this chapter.
Take great care that you use the correct sensors (contact sensors,
immersion sensors, outdoor sensors) since, if incorrectly applied,
error messages and resulting malfunctions in the control system can
then occur.
All of the sensors in the HDG Hydronic are PT 1000 sensors.
