Typical applications include lighting control based on PIR presence detection or a light switch connected to FAM-W. EMRM can also be used for relay output control based on heating demand, cooling demand, second-stage heating or second-stage cooling.
The control logic is handled by FAM-W. EM-RM provides the physical relay output and is configured in the TROX Ox ServiceApp.
Each EM-RM includes one normally open relay output. Several EM modules can be connected in daisy chain, with up to four modules connected to one FAM-W. The maximum cable length between two units is 10 m.
Each module is assigned an address from 1 to 4 using DIP switches. Each EM-RM connected to the same FAM-W must have a unique address.
EM-RM has one relay input and one switched relay output. The voltage connected to the relay input is made available on the relay output when the relay is activated. EM-RM receives its operating voltage from FAM-W via the RJ45 connection, but the voltage to be switched must be connected separately to the relay input.
The relay function is configured in the TROX Ox ServiceApp.
EM-RM can be configured for different room-control functions, including:
Light control: Relay output controlled by PIR presence detection or light switch connected to FAM-W
Heating demand: Relay output activated based on heating demand
Cooling demand: Relay output activated based on cooling demand
Second-stage heating: Relay output activated when the room temperature is further away from setpoint than the configured second-stage heating threshold
Second-stage cooling: Relay output activated when the room temperature is further away from setpoint than the configured second-stage cooling threshold
The adjustment points and control conditions are configured in FAM-W using the TROX Ox ServiceApp.
