Program Area "Cooling; Select Program Aerea; Setting The Mode Of Operation "Cooling - Alpha-InnoTec Luxtronik Operating Manual

Program area "Cooling"

The "cooling" function (with automatic changeover to heating or
cooling mode, depending on requirements) can be used with a
mixing circuit.
To use the cooling function with further mixing circuits, the instal-
lation of the expansion board (accessory subject to a charge) is
necessary.
The program area "Cooling" must be set by authorised service
personnel during commissioning.
Necessary setting:
Mixing circ 1 = Cool
 page 20, program aerea "Service", section "Determining
system setting", "Mixing circ 1"
ATTENTION
If a cooling circle mixer is connected, it is imperative to ac-
tivate the function "Cooling", as otherwise malfunctions
will occur in the mixer connected.
ATTENTION
The use of cooling requires that you integrate a dew point
sensor in the system. This must then either be connected
in series with the cooling sensor or used instead of the
bridge, if cooling is provided via the flow cooler.
NOTE
The minimum flow temperature of cooling is factory set to
18 °C. This value can be changed in the menu "Determin-
ing temperatures" in the menu item "min. flow cooling"
 page 17, program area "Service", section "Making set-
tings", "Determining temperatures"
