The instructions state that MCR308 has open-collector outputs. This means that they can be connected direct to Comfort Zone Inputs. You do not need the relay interface module they mention
Treat the MC308 outputs as regular contacts. You can connect the DEOL resistors ie 2K7 in series and 4K7 in parallel to the outputs and set Comfort zone shunts to DEOL, or set NO EOL resistors on the Comfort zone shunt and do not connect any EOL resistors.
The MCR308 shows EOL resistors, but does not require these EOL resistors, that depends on the Alarm control panel only
