Remark
Free contacts 5 A, 250 V. Closed when heat exchanger is operating and there is a heating demand.
Free contacts 5 A, 250 V. Closed when there is a cooling demand and when one of the cooling outputs
has an output signal.
Free contacts 5 A, 250 V. Closed when an alarm is initiated.
Free contacts 5 A, 250 V. Closed when an alarm is initiated.
Free contacts 5 A, 250 V. On/off control of the cooling unit. Activated from the hand-held terminal.

230 V AC. 23 fixed phase, 21 controlled phase, 22 neutral.
Used to stop unit via normally closed contacts. Bridged when delivered. Terminals 25 and 26 are
connected during operation. If this connection is broken the unit will stop.
Used to stop unit via external fire or smoke detector. Bridged when delivered. Terminals 27 and 28 are
connected during operation. If this connection is broken the unit will stop and trigger the alarm.
External contact function. Switches timer between stop and low-speed operation.

External contact function. External alarm can be obtained for GOLD.
Output for EA flow indication, 0–10 V DC. Max. load 2 mA at 10 V DC.
Output for SA flow indication, 0–10 V DC. Max. load 2 mA at 10 V DC.
Output for constant 10 V DC. Max. load 10 mA.
Output for cooling 0–10 V DC. Max. load 2 mA at 10 V DC.
External closing contact function. Works in parallel with reset button on hand-held terminal.
Input 0–10 V DC. If supply air control is selected the supply air temperature set point will be offset. If
exhaust air control is selected the exhaust air temperature set point will be offset. Displacement ±5°C. If
ERS control is selected the EA/SA differential will be offset. The differential cannot be <0°C. The EA/SA
differential decreases as the input signal increases. Can be activated from the hand-held terminal.
Input 0–10 V DC. Controls exhaust air fan speed by means of boosted flow or VAV control.
Input 0–10 V DC. Controls supply air fan speed by means of boosted flow or VAV control.
Control Voltage 230 V AC. Max. load 1 A. Can be isolated by the safety switch.
Draws power across the power supply fuse.
Control Voltage 24 V AC. Max. load 16 VA. Can be isolated by the safety switch.
