The RTD-RA offers several operation modes which can be set using the DIP switches. Note that the RTD-RA does not have relays.
- Stand-alone mode
- While DIP switches 3 - 8 must be set to OFF position, DIP switches 1 and 2 determine how hardwired input S1 operates and whether Mode and Sepoint can be set by the user.
- DIP Switch 1 determines the operation of the unit when S1 is initially Closed-Circuit.
- DIP switch 2 determines whether mode and setpoint are controlled solely by the RTD-RA.
- While DIP switches 3 - 8 must be set to OFF position, DIP switches 1 and 2 determine how hardwired input S1 operates and whether Mode and Sepoint can be set by the user.
- For further information see the attached installation instructions and the article How to install the RTD-RA.
- Modbus Slave Operation
- For control of the indoor unit via Modbus and remote controller.
- DIP switches 1 and 2 determine the timeout function (see attached installation instructions - page 10)
- DIP switches 3 - 8 are used for setting the Modbus address and must be >0.
- For further information see the attached installation instructions and the article How to install the RTD-RA.
- RTD Clone Mode
- The RTD-RA clones, i.e. copies the control functions Setpoint, Fanspeed, Mode, Louvre, On/Off and Force Thermo Off from the Clone Master. The Clone Master is the RTD interface with the next lower Modbus address.
- Multiple RTD-RAs can operate in Clone Mode on a network, e.g. Clone Master with address '0' and 63 clones.
- For further information see the attached installation instructions and the article How to install the RTD-RA.
- Duty/Standby Slave Operation
- RTD-10 Duty/Standby Slave Operation.
- For further information see this article RTD-10 Duty/Standby operation mode, the attached RTD-RA installation instructions, and the article How to install the RTD-RA.
- RTD-20 User Control Zone
- In a RTD-20 retail network the RTD-RA can be configured to operate as an RTD-20 User Control Zone (UCZ). A User Control Zone allows users to alter unit operation during the OCCUPIED period. The Zone Primary co-ordinates the User Control Zone and ensures the zone is shut down when UNOCCUPIED or during FIRE conditions. User Control zones can be configured to support areas with permanent or temporary occupancy.
- For further information see the RTD-20 installation instructions, the attached RTD-RA installation instructions and the article How to install the RTD-RA.
- Custom BMS algorithms
- If your application requirements are not covered by above operation modes (or any other RTD interface) then set the RTD-RA to Modbus slave operation and implement a custom solution on your BMS system.
