• Expands Genesis Controller capabilities by providing a numeric output display, numerical value input, a single toggle digital input switch and single LED display output for distributed control via RS485. The GenII MZSAH REM Module provides a visual display of upto 6 control values and a means to set up to 6 parameters.

Application Notes
A Genesis Controller must have version 4 firmware installed to support REM Modules. Version 4.1 or higher Config Software must be used to configure a Genesis Controller that has REM Modules connected to it.

One Genesis Controller can have up to 15 GenII MZSAH REM Modules* connected to it via the REM comms bus. For detailed connection information to the pre version 5 Genesis Digital Controller Family, please refer to Innotech Cabling Manual (.pdf 1.54MB).

POWER SUPPLY

• Voltage: 24 volts AC ±10% @ 50/60Hz.
• Power Consumption: 3VA max.

The operating voltage must meet the requirements of Safety Extra Low Voltage (SELV) to EN60730. The transformer used must be a Class 2 safety transfomer that has the energy and voltage limiting characteritics as described in the National Electrical Code, ANSI/NFPA70. It must also be sized and fused in compliance with local safety regulations.

INPUTS

• Push buttons for adjusting control values.
• Push button for toggling of “digital function”.
• Push button for zone selection.

OUTPUTS

• No physical ouputs.
• Display of Temperature and Setpoint.

TERMINAL IDENTIFICATION

• 1 = 24V AC Supply.
• 2 = 0V AC Supply.
• 3 = Earth.

NOTE - Terminal 3 is for the protection of the Comms circuitry and must be connected to a good electrical bonded Earth.

COMMS CONNECTION

SHLD 1	=	Shield from incoming Comms Cable.
+	=	RS 485 (+) signal.
-	=	RS 485 (-) signal.
SHLD 2	=	Shield from outgoing Comms Cable.

TEMPERATURE RATINGS

• Storage 0 to 50°C non-condensing.
• Operating 0 to 40°C non-condensing.

ENCLOSURE
The GenII MZSAH REM Modules are housed in switchplate that mounts in standard electrical wall plates.

• Colour: White.
• Mounting: Wall mounted.

INSTALLATION

• The Cable run between the GenII MZSAH REM and the GenII RMI should not exceed 500 mtrs. The Comms wiring requires cable especially suited for RS485. Other shielded cable is not suitable and may cause spasmodic Comms failures.
• Strictly follow the guidelines when installing the Comms wiring as outlined in the Genesis II Installation Manual.
• Mount the GenII MZSAH REM in a dry and clean location free of excess vibration.

The REM Address must be set by Programming Parameter 0. Please refer to the Progam Functions section of this data sheet for more specific information regarding this.

WIRING

• The cable used for RS485 Comms must be shielded single twisted pair, 120 ohms character impedence, 36 to 45pF per metre capacitance between conductors.
• The Comms cable must be organised as a bus topology. That is, starting at one end, devices are connected to it until the other end of the cable is reached. No “stubs” are allowed. To connect a device to the cable, as cut is made in the cable at the point where the device is to be situated along it. Then, the two new ends of the cable are wired into the device. The shields from the two new ends are then terminated into the terminals marked SHLD1 and SHLD2. Refer to the Genesis System Network Installation Instructions for more information.
