Connection – Definitions
1 Power switch (emergency off function)
Connect the on/off switch of the PC casing. Detach the 2-pin-jack/socket of power switch from
main board. 2 pin Jack of the power-switch cable is connected to the left, next on right connect the
2 pin cable and join it with the main board at the power-switch plug. (see the handbook of the main-
board for further details) The pins which are connected together lay vertically one below the other.
In an respective configuration of a control-loop the Heatmaster can shut down your PC immediately,
when the alarm status achieves Level 3. The normal on/off function thereby hasn't changed.
2 Relays
Connect here a device of your choice or a further relay. The Heatmaster relay delivers max. 24
Volt / 30 Watt of switching voltage.
ATTENTION: Don’t connect 110/220 Volt devices directly and don’t apply 110/220 Volt also!
Mortal danger
Fire danger and
destruction danger!
3 Alarm buzzer
2-pin connection for the acoustic alarm enclosed. The pins which are connected together lay
vertically one below the other(above GND, below voltage).
Attention: If connection is inverted, there is no acoustic warning signal!
4 Thermo sensors
Connections for 5 air or liquid thermo sensors. A sixth sensor is on the Heatmaster board. The
pins which are conneted together lay vertically one below the other.
5 Flow sensor / Flow meter
Connect a flow meter. The flow meter should use the 3 pin standard connection of a PC fan.
