  • Page 8: Operation By Thermoregulator With Periodic Activation

    Controller for HP_OWER 1.8.2 OPERATION BY THERMOREGULATOR WITH PERIODIC ACTIVATION The function is disabled if P17= 0 (default). If the pump is set to operate by thermoregulator call (P03 = 1, default), it will be activated periodically for a time period defined by the parameter P17 (in seconds) after a counting time set by the parameter P16 (in minutes), activated when the pump is turned off for satisfied thermoregulation.

    Controller for HP_OWER In sanitary hot water production mode, the pump will operate at the maximum speed. 1.9 REMOTE ON/OFF AND SUMMER-WINTER MODE SELECTION The terminal block has two digital inputs to control the unit via an external consent. SW-SW: Summer/winter switching mode input via remote control.

  • Page 10: Memory Of The Sensor In Heating Mode

    Controller for HP_OWER 1.11.1 MEMORY OF THE SENSOR IN HEATING MODE In the case of commutation from water users to the sanitary water, the temperature sensor changes from a "water outlet temperature sensor" to a "water tank temperature sensor". For such reason, in heating mode, the last value read by the sensor will be memorised before changing to sanitary mode.

  • Page 11: Call Of Domestic Hot Water Production From Digital Input

    Controller for HP_OWER The memory function will be interrupted: - When the temperature detected by the sensor becomes lower than the memorised value; - Or after a duration equal to b06 seconds (default 45 seconds). 1.11.2 CALL OF DOMESTIC HOT WATER PRODUCTION FROM DIGITAL INPUT Differently to the use of the temperature probe, the activation of the sanitary hot water function may be by closing the digital input (SAN-SAN terminals enabled as digital input) of the minichiller.
  • Page 12 Controller for HP_OWER NOTE: turning off the unit remotely (onoff-onoff terminals), or by the on board keyboard, or by a remote keyboard does not affect the sanitary operating mode. Once the H10 parameter is set to be 1, the unit switches to sanitary priority as soon as powered. The on board display shows the temperature measured by the sensor placed inside the sanitary water tank.

  • Page 13: Heating Mode On Sanitary Accumulation

    Controller for HP_OWER 1.12 HEATING MODE ON SANITARY ACCUMULATION If the parameter H83=1, the appliance exploits the accumulation tank for sanitary hot water also to heat the plant side. In these conditions, the relay which controls the sanitary valve will be also energized during heating operation and not only in sanitary mode.

  • Page 14: Auxiliary Electric Heater Of The Plant In Defrost Cycle

    Controller for HP_OWER 1.13.1 AUXILIARY ELECTRIC HEATER OF THE PLANT IN DEFROST CYCLE During the defrost cycle (see Paragraph 1.19), by setting r21=1 (in addition to r10=1 and r24=1 or 3) the electric heater of the plant side will be activated if required (detected (regulating) temperature lower than the water setpoint minus r11 (°C)), without waiting for the time defined by r12.

  • Page 20: Indication On Summer/Winter Operation

    Controller for HP_OWER By setting r32 = 2 or 3, the boiler control is activated (using the thermoregulator inside the boiler is used) regardless of the minichiller (HP) thermoregulation. If the boiler is not equipped with independent circulator, it is necessary to keep utilization pump active. In the presence of the plant call function (with boiler working on plant side) and the plant is fullfilled (or with minichiller (HP) is not ON) the boiler thermoregulation is not enabled.
