The new generation of cooling controller from Alphacool: The Heatmaster II
The new Alphacool Heatmaster II was developed in Germany over multiple years, and has continuously been improved considering the experiences from the first version. Hence we are now, after a development and testing period of almost 3 years, able to present the best Heatmaster of all times!
The whole manufacturing process is done in Germany, ensuring highest quality of manufacturing and stringent quality control.
Alphacool’s Heatmaster 2 board is more than just a simple control and monitoring unit. It is the central component for a multitude of optional expansions and possibilities, some of which are already available and many are currently being developed! With this controller module you are making a step towards the future!
The unit draws power via the proven and reliable 4-Pin Molex power connection to the computer’s PSU. Simply connect a 4-Pin PSU connector the board and the unit can be started up!
The data transfer from and to the Heatmaster respectively the corresponding software is achieved via an internal USB connection cable. It is extremely important to ensure the right polarity of this connection to prevent damage to your hardware or Heatmaster. More information is provided in the Operating manual on page 10.
6 individual channels allow connection, control and monitoring of a large number of fans. Each channel can put out up to 18W of power, hence even allowing multiple fans to be connected (depending on the fan type).
Pumps / flow rate sensors:
3 additional channels allow connection of multiple fans or also flow rate sensors. The sensor can be monitored with the Heatmaster II. Control of the pumps is also possible by connecting the optionally available analogue adaptor (not included) parallel to a fan channel. In this configuration the 10W limit must still be observed. By adaptation it is possible to connect a wide array of pumps and flow rate sensors.
The overall power draw from all fan and pump channels must not exceed 75 Watts or 6 Amps at 12 Volts. There are different possibilities to distribute the power draw between the channels.
Without additional cooling (stock):
A maximum power of 18W can be drawn per channel. This means that e.g. 4 Laing DDC Plus pumps could be connected to separate channels when no fans are connected. Alternatively 6 Laing DDC 1T without connected fans can be controlled. When only one or two pumps are connected (pumps from other manufacturers, such as Eheim, Phobya or Hydor, with a maximu power consumption of 18W can be used as well), the remaining power envelope can be used to power fans on the other channels. We recommend using an additional fan for cooling of the Heatmaster2.
The Alphacool VPP or TPP pumps or Eheim pumps from model 1250 upwards cannot be used without additional cooling for the Heatmaster2.
With additional cooling (Added component: Alphacool Heatmaster 2 cooler, Item No.: 11045)
The advantage of operation with the added water block is an increased power envelope for the individual channels. The maximum overall power draw of 75 Watts must not be exceeded, even with additional cooling! With this cooler it is possible to draw up to 38 Watts of power per channel. The power can still be distributed amongst the channels, just as when using no additional cooling.
Pumps and flow rate sensors known to be compatible:
-EK-DCP 2,2 /4,0
-Laing DDC-1T / Laing DDC-1T Plus ( requires active cooling) (as well as the RT models)
-Laing D4 & D5 ( ( requires active cooling)
-Alphacool TPP644 & VPP655 ( requires active cooling)
Please note that the Alphacool pump adaptor may be needed for some models!
