GENERAL FEATURES
Accessories
Coil protection grilles - GP
It comprises a painted electrowelded grille that protects the finned coil.
Rubber vibration dampers - AVG
These reduce the transmission to the machine support surface of mechanical vibrations generated by the compressor and fans
during their normal operation. The number of vibration dampers depends on the version. To ensure the efficiency of this
accessory it is advisable to use vibration-damping joints on the plumbing connections.
Tank antifreeze heating element - RAG
Activated together with the plate-type exchanger antifreeze heating element, its purpose is to keep the water in the storage tank
at a suitable temperature to prevent ice forming during winter idle periods.
Supplementary heating elements - REL
They supplement or substitute the heating power supplied by the heat pump and are managed by the unit’s controller with two-
step logic. They also substitute the tank antifreeze heating element accessory (RAG).
Remote control - CR
The remote control is suitable for wall mounting and has all the control and display functions available on the unit’s interface. It
therefore enables complete remote control of the unit.
Serial interface - KMB
It enables communication with the unit’s controller and monitoring the operating conditions by means of Modbus communication
protocol. Use of the RS485 serial line ensures the quality of the signal up to distances of approx. 1200 metres (extendable by
means of special repeaters).
Programmer clock - OP
It allows the unit to be turned on and off according to a preset programme by operating on the digital input available on the unit’s
control card (remote on-off).
