Min. supply temperature
Options:
0…3…100 °C
The supply setpoint temperature output by the module is limited using this parameter. This is a
safety function that ensures a supply setpoint temperature too low for the cooling system is not
output under any circumstances. For example, the supply setpoint temperature for cooling ceiling
can be limited to minimum 14 °C.
Switch off if no room demand
Options:
No (checkbox cleared)
Yes (checkbox selected)
With this function the module monitors the room control values and automatically switches on and off the
cooling distribution circuit controller connected accordingly.
It is a prerequisite for this function that all control values from the room valves in the cooling distribution
circuit are available and connected to the ASM input socket. There must therefore not be any conventional
thermostats in the cooling distribution circuit.
This function is affected by the
Enable cooling circuit control based on ASM input socket
function. If both
functions are activated, the
Enable cooling circuit control based on ASM input socket
Selection of
Yes
option:
Dependent parameter(s)
Switch on if the room demand is higher than
Options:
0...10…100 %
The module sends a switch-on command to the cooling distribution circuit controller if the highest
room control value present on the ASM input socket exceeds this value.
Switch off if the room demand is equal to or less than
Options:
0…100 %
The module sends a switch-off command to the cooling distribution circuit controller if the highest
room control value present on the ASM input socket is the same as or less than this value.
