IOM / Rooftop Smart and Linéa™ Range - Page 85
This option is used for making a connection to the BMS
only, by a set of volt free contacts.
It requires the addition of a KP05 card, if this is not already
in place, and a KP12 card.
Input connection must be by screened cable only.
Limits of relays :
• 10A – 250V with resistive load
• 4A – 250V with inductive load.
Input Function
A Instruction shift :
A 0/20mA signal can be used to add a linear
shift of 0 to 10 °C to the setpoint temperature
(mid-point between air-conditioning and
heating setpoint). If your command signal is
a different type, our engineers can advise you
on the type of interface to use before input to
the CLIMATIC™ (0-10V with interface)
B Unit on/off (ROOF-TOP on when unit is off).
C Contact - force night operation
D Contact - force day operation
E Contact - force operation at 50%.
F Lock heating function
G Lock air-conditioning function.
