6 Fan / Pump connections
Four standard PC fans or pumps could be connected with 12V DC and up to 24 Watt per
connection. Normally one pump should be used in connection 1 (basic configuration), if one pump
should be controlled through the Heatmaster (see Appendix 3).
ATTENTION: By using with more powerful consumers some components such as Coils etc.
could become hot! Overload danger!
Please consider here the monitoring facilities with the Heatmaster on board sensor and use
a fan if necessary by the temperature 65°C upwards, which cools the electronic system of
the Heatmaster. Otherwise make sure that the Heatmaster is mounted with a casing air flow.
Only two fans at one connection are allowed, if the second fan is connected with a Y-
adapter, which doesn’t transmit a tachosignal (third cable misses), and if both fans consume
not more than 24 Watt together.
Please consider that there will be an abrupt capacity fall-off of a pump by regulating it in a
certain shortfall of the voltage, depending on the type of pumps. This is not an error
function of the Heatmaster, usage on your own risk
7 Power connector
Connect here 4-pin socket cable of your PC-power unit.
ATTENTION: if you operate 4 consumers (pumps or/and fans), you need 96 Watt already.
Consider the whole consumption of your PC and output of your PC-power unit, use a special
12 busbar (cable loom), which is not loaded with further strong consumers.
ATTENTION: Don’t disconnect the power cable during operation and also don’t connect it
during the operation (USB Cable already connected). It could cause damage on Heatmaster
or lost of settings.
8 Main board (CPU FAN)
Connect the enclosed 3-pin cable (Socket/Socket) with the fan connection of CPU fan on the main
board. In case of air cooling CPU, connect the CPU fan to the Heatmaster now. With this the
Heatmaster can be connected to all the alarm and monitoring functions (alarm level 2) of the main
board ( see handbook of your main board, BIOS setups).
