WARNING Wiring, protection and earthing must be installed in compliance with local regulations. No internal line protection for supply lines to external consumers (Q11, Q12, Q14 ). Risk of fire and injury due to short-circuits! ● The AC 230 V mains supply line must have an external circuit breaker with a rated current of no more than 10 A. ● Adapt the line diameters as per local regulations to the rated value of the installed overcurrent protection device. ● Only use valves rated for AC 24…230 V.

OFF The valve or compressor receives the CLOSE command via control output Q14 when both of the following conditions are met. ● The acquired room temperature lies by half the switching differential above the setpoint (heating mode) ● Control output Q14 is energized for more than the “Minimum output on time” (factory setting: 1 minute) Control output Q11 delivers a control command which is inverted to the control command at output Q12 and which can be used for normally open valves.
