Function
Remarks
1,2,3
Connections for EIA -485
1= Communication connection A/RT+, 2= Communication connection B/RT–, 3= GND/COM.
4,5
External stop
Stops the unit by opening the circuit. On delivery, this function is fitted with a jumper. If the connec-
tion is interrupted, the unit will stop.
6,7
External fire/smoke function 1
External fire and smoke function. On delivery, this function is fitted with a jumper. If the connection is
interrupted, the function will trip and initiate an alarm.
8,9
External fire/smoke function 2
External fire and smoke function. On delivery, this function is fitted with a jumper. If the connection is
interrupted, the function will trip and initiate an alarm.
10,11
External alarm 1
External contact function. Optional: Normally open/normally closed.
12,13
External alarm 2
External contact function. Optional: Normally open/normally closed.
14,15
External low speed
External contact function. Oversteers the timer from stop to low speed operation.
16,17
External high speed
External contact function. Oversteers the timer from stop or low speed to high speed operation.
18,19
Demand control
Input for 0-10 V DC. The input signal influences the supply air/extract airflow set point if the unit is
operating in the demand control mode. For connection of sensors, for example CO
2
, CO and VOC
20,21
Circulation pump, heating circuit
Independent contact, max. 5 A/AC1, 2 A/AC3, 250 VAC. Closes on a heating load.
22,23
Circulation pump, cooling circuit or
cooling on/off, 1-step operation
Independent contact, max. 5 A/AC1, 2 A/AC3, 250 VAC. Closes on a cooling load.
24,25
Cooling, on/off, 2-step operation
Independent contact, max. 5 A/AC1, 2 A/AC3, 250 VAC. Closes on a cooling load.
26,27
In-operation indication
Independent contact, max. 5 A/AC1, 2 A/AC3, 250 VAC. Closes when the unit is operating.
28,29,30
Damper control
24 VAC. 28= Controlled 24 VAC (G), 29= 24 VAC (G), 30= 24 VAC (G0).
31,32
Control voltage
1)
24 VAC control voltage. Terminals 31-32 are loaded with a total of 16 VA. Opened by means of the
safety isolating switch.
33,34
Reference voltage
Output for constant 10 VDC. Max. permissible load: 8 mA.
35,36,37,38 Control, recirculation damper
The recirculation damper can be loaded with max. 2 mA at 10 VDC. 35= 24 V AC (G), 36= 24 V AC (G0),
37= 0-10 V DC control signal, 38= 0-10 VDC feedback signal.
The max permissible common load on terminals 31-32, outputs for Heat/Cool and damper output (terminals 28-30) is max 32 VA (SD) eller 50 VA (RX/PX/CX).
The max. permissible load on the correspond-
ing connection is 16 VA.
