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).
GOLD 100/120: If more than 16 VA is required, use wiring terminals 201 (G) and 202 (G0). Terminals 201-202 can be loaded with a total of max.

Stops the air handling unit by opening the circuit. On delivery, this function is fitted with a jumper. If
the connection is interrupted, the air handling unit will stop.
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.
