FM3 and FM5 functional modules
If the FM3 and FM5 functional modules are installed in a system, each additional installed FM3 functional module adds two
mixed heating circuits to the system.
The potential configuration (FM3+FM5) corresponds to a defined terminal assignment for the FM3 (→ Chapter 4.6) functional
module.

When connecting, pay attention to the polarity!
S6 to S11 sensor terminals: An external control can also be connected
S12, S13 signal terminals: I = input, O = output
R7/8, R9/10, R11/12 mixer output: 1 = open, 2 = closed
You can configure the contacts for external inputs in the system control.
–
Open, deact.: Contacts open, no heat demand
–
