R-ION Application Examples
These examples are provided to demonstrate the versatility of the R-ION Individual Room Control product range. The list is by no means conclusive.
 F-1
FAN COIL UNIT CONTROL
Room control for heating and cooling with a fan coil unit. Automatic closing of the control valves if the window is open. Room temperature measurement integrated in wall-module.
RS485 Modbus/BACnet comms to supervisory system (BMS).
Inputs
- 1 x voltage-free digital input for window contact
- 1 x voltage-free digital input for occupancy input
Outputs
- 3 x relay for 3-level fans, AC 230 V, max 400 VA
- 4 x triac for heating/cooling valves
(thermoelectric on/off, PWM or motorized floating actuators)
Option
- 2 x 0-10 Vdc for modulating valves
- Auxillary 24 Vac power output for valve/damper actuators
