Functions

VAV systems via On/Off or modulating control outputs or KNX LTE-Mode:
· Single-duct system
· Single-duct system with electric heater
· Single-duct system and radiator/floor heating
· Single-duct system with heating/cooling coil
The room thermostats are delivered with a fixed set of applications.
The required application is selected and activated during commissioning using one
of the following tools:
· Synco ACS
· ETS
· Local DIP switch and HMI
· Operating modes: Comfort, Economy (energy saving) and Protection
· Output for VAV box/air damper/VAV compact controller: DC 0...10 V/3-position
(triac)/KNX LTE-Mode
· Output for heating/cooling coil: On/Off, PWM or 3-position (triac)/DC 0...10 V
· Output signal inversion as an option (DC 0...10 V à DC 10...0 V)
· Automatic or manual heating/cooling changeover
· Backlit LCD
· AC 24 V operating voltage
· Indoor air quality (IAQ) control loop with external CO
or KNX LTE- and S-Mode)
· Window contact (RDG405KN)
· Presence detector (RDG405KN)
· Receive temperature via bus (RDG405KN)
· Selectable DC input (RDG405KN)
