4.0 Wiring Overview
AO1 = outpout 0-10V for external hydraulic postheater (option) T1 = from outdoors T° sensor (prewired)
DO1 = KWout = output PWM for KWout power regulation (option - prewired) T2 = from indoors T° sensor (prewired)
DO2 = KWin- PX: output PWM for KWin power regulation (option - prewired)
| RX SPEED PWM - RX (prewired)
T3 = to outdoors T° sensor (prewired)
AO2 = RX SPEED 0-10V - RX (option) T5 = supply T° sensor for IBA/KWout coil (option)
AO3 = 0-10 V output to control cooling capacity T7 = IBA/EBA anti freeze protection T° sensor (option - prewired for IBA)
AO4 = outpout 0-10V for internal hydraulic postheater (option - prewired) T8 = Cooling coil frost protection sensor
DO3 = BYPASS OPEN- PX (with rotary actuator) (prewired) IN1 = FIRE ALARM
DO4 = BYPASS CLOSE - PX (with rotary actuator) (prewired) IN2 = BOOST
DO5 =
DAMPER 1 (with or without spring return, Imax = 0.5A DC) (option - prewired) IN3 = BYPASS ACTIVATION OVERRIDE
DO6 =
DAMPER 2 (with or without spring return, Imax = 0.5A DC ) (option - prewired) IN4 = Drain pan full contact (only for LP Unit - prewired)
DO7 = HEAT OUTPUT (open collector; Vmax=24 VDC; Imax=0,1 A) K1: Airow MODE = m³/h K1
DO8 = COOL OUTPUT (open collector; Vmax=24 VDC; Imax=0,1 A) Demand/Pressure control = START/STOP
DO9 = ALARM OUTPUT (open collector; Vmax=24 VDC; Imax=0,1 A) Torque MODE = %torque K1
DO10 = AL dPA OUTPUT (open collector; Vmax=24 VDC; Imax=0,1 A) K2: Airow control = m³/h K2
DO11 = FAN ON OUTPUT (open collector; Vmax=24 VDC; Imax=0,1 A) Demand/Pressure control = 0-10V INPUT
ADI1 = BYPASS POS - PX | RX SPEED FEEDBACK - RX (prewired) Torque control = %torque K2
ADI2 = SUPPLY FILTER dPa K3: Airow control = m³/h K3
ADI3 = EXTRACT FILTER dPa Demand/Pressure control = % ON K3 or 0-10 V INPUT
Torque control = %torque K3
F1 = FAN 1 (SUPPLY) RJ1 = RJ12 connector for TACtouch (option)
F3 = FAN 3 (EXHAUST) RJ2 = RJ12 connector for Modbus Pressure CP mode (option)
RJ3 = RJ12 connector for Modbus Pressure CA mode on supply ow (option - prewired)
SAT COM = SAT MODBUS or SAT KNX or SAT ETHERNET or SAT WIFI - (option)
RJ4 = RJ12 connector for Modbus Pressure CA mode on exhaust ow and defrost
detecting (option - prewired)
SAT RELAY: only used for global lp, then premounted and prewired
SAT RELAY OR1 - linear actuator for LP linear bypass actuator - forward) GREEN LED ON = POWERED ON
SAT RELAY OR2 - linear actuator for LP linear bypass actuator - backward RED LED ON = ALARM
+24 = +24V DC (min: +22V DC; max: +26V DC). 0,8 A max
+12 = +12V DC (min: +11,49V DC; max: +12,81V DC). 0,3 A max
