4Scheda Pco OEM monocircuito Key utilization programmation /alarms KEY: programmation /alarms KEY: allows the access the programmation parameters or,with red led ON, to display the alarm list and and to reset them mode up KEY: mode up KEY: Allows to change from the summer to the winter mode (for heat pump), the scroll of the parameters and the increase of the displayed value.
5Scheda Pco OEM monocircuito Utilizzo tasti on/off down KEY: on/off down KEY: Allow the switch on and off of the unit,the scroll down of the parameters and the decrement od the displayed value. up + down KEY:up + down KEY: If you are inside of a group of masks allows to go back to the upper level group of masks.Allows also to confirm the new inputed values.

Comparison OLD - NEW TIME ZONE MANAGEMENT BY CLOCK BOARD: YES Management of 4 daily time zone with the chance to change the set point or to manage the On/Off time of the unit NO
9Scheda Pco OEM monocircuito Comparison OLD - NEW 2 PUMPS MANAGEMENT: NO YES Activable by parameter under manufacturer menu.Activable by parameter under manufacturer menu. Manage the pump rotation according to the working N° of hours one in stand by to the other.Manage the pump rotation according to the working N° of hours one in stand by to the other.
Comparison OLD - NEW COMPATIBLE SUPERVISION SYSTEMS : Only Modbus Carel Modbus (Accessory KRS485) Lonmark (Accessory KFTT10)
11Scheda Pco OEM monocircuito Comparison OLD - NEW NEW ALARMS MANAGED BY THE ELECTRICAL BOARD : Wrong phase sequence :activated from the phase monitor integrated in the electrical board Hi and low Voltage supply:activated by a board that measures the width of the phases and verify eventual anomaly in the absorption of the phases.
Accessory: Remote keyboar KTR Alarm hour and date (with clock board) Total N° of memorized alarms Alarm code and description Evap water inlet/outlet temperature Compressors working hours Condensation Temperature/pressure Stato compressor/s and fans satus one istant before the alarm. NEW’ :ALARM HISTORY FOR EACH ALARM IS MEMORIZED:
