Description
The KPM30 and KPM31 regulation unit derives from Giacomini's extensive
experience in the field of thermoregulation of heating and cooling
systems. The KPM30 regulation unit is a device designed to be used in
Giacomini radiant heating and/or cooling systems in combination with bus
thermoregulation components and other communicating devices with
compatible protocols. The KPM30 module is equipped with a display and six
multifunctional keys; this allows programming of the system parameters via
a guided menu and the subsequent monitoring of the system by the user.
The KPM30 module allows for quick connection to the ambient thermostats
K492B, K495B and K495L and to the KPM35 expansion boards.
In addition, the operation of the circulator and the activation of the mixing
valve servo-control is managed automatically.
The KPM31 version has the same characteristics as the KPM30 but without
the display, therefore it must be installed in combination with the remote
display KD201 (which is an optional accessory for the KPM30 model). Thanks
to the plug-in terminals and the design compliant with the DIN standard, it
can be installed in accessible electrical panels.
Versions and product codes
The KPM30/KPM31 series is available in different versions:
• KPM30Y001, KPM31Y001: stand alone for the control of one mixing valve
• KPM30Y002, KPM31Y002: stand alone for the control of two mixing valves
• KPM30Y003, KPM31Y003: for the management of one to three ambient
thermostats and control of a mixing valve, a dehumidifier or a fan-coil
• KPM30Y004, KPM31Y004: for the management of one to sixteen thermostats
and control of a mixing valve and seven air treatment machines (to be used
in combination with the KPM35 expansion boards)
• KPM30Y005, KPM31Y005: for the management of one to sixteen thermostats
and control of two mixing valves and seven air treatment machines (to be
used in combination with the KPM35 expansion boards)
