7.17 Connecting the pressure transmitters

You can connect a pressure transmitter to both the heating circuit and the collector. Transmitters allow you to monitor circuit pressures and set limit values for alerts.

Connect the pressure transmitters to the expansion module TC1.7 as follows:

Heating circuit pressure transmitter (H11):

• 24 VAC: G

• GND: M

• 0–10 V: X6

Collector pressure transmitter (H12):

• 24 VAC: G

• GND: M

• 0–10 V: X7
