Mounting
Wiring
· Comply with local regulations to wire, fuse and earth the thermostat
· The power supply line must have an external fuse or circuit breaker with a rated
current of no more than 10 A
· Isolate the cables of inputs X1-M, U1-G0 and D1-GND for AC 230 V if the
conduit box carries AC 230 V mains voltage
· Inputs X1-M or D1-GND: Several switches (e.g. summer/winter switch) may be
connected in parallel. Consider overall maximum contact sensing current for
switch rating
· Isolate the cables of KNX communication input CE+/CE- for AC 230 V if the
conduit box carries AC 230 V mains voltage
· Disconnect the unit from power supply before removing it from its mounting
plate
