Meaning
0- Antifreeze heater operating in standby without pump activated.
1- Antifreeze heater installed and operating even in standby by pump is
2 switched on.
2- With an external air temperature of < 3° the pump is activated for 2'
every 30' to monitor the water temperature throughout the entire system.
Supplementary heater presence:
0- no supplementary heater;
1- supplementary heater fitted but not activated during domestic hot
water production;
2- heater activation command used as enable for starting external boiler;
4
3- Supplementary heater fitted and activated during domestic hot water
production;
4- electric heater activation command used as consent for activation of an
external boiler also in a supplementary mode. See paragraph 4.1.5.
0 – Season (HOT/COLD MODE) defined by parameter 0, ON/OFF command
set by control panel on-board machine.
1 – ON/OFF command from remote contact, season defined by parameter
0.
2 – ON/OFF command from control panel on-board machine, season
3
defined by contact.
3 – ON/OFF command from remote contact, season defined by contact.
If remote contacts are enabled, they take priority over commands issued
by any BMS supervisor.
Heating cable activated with an external air temperature lower than the
value of this parameter.
10.0
Heating cable deactivated with an external air temperature higher than
the value of this parameter, plus 1.0° hysteresis.
This parameter is used to define the wait-time for inversion of the 3-way
valve in domestic hot water production system. During this time the
machine goes into standby, terminating any defrosting phase. When the
time is finished the machine turns to ON to produce domestic water. This
function is active during the shift from normal mode to domestic water
600 mode, and vice-versa during the shift from domestic water mode to
normal mode.
The pause is only respected if the chiller remains ON and the ID6 contact
(or supervisor) is used to for the domestic/plant request. The pause is not
respected if the ON/OFF (display, remote contact or supervisor) is used.
0= Input not enabled.
1= Multi-function input enabled (ID4) used as environment thermostat.
Contact closed = normal operation. Contact open = compressor is switched
off and pump remains on.
2= Multi-function input enabled (ID4) used as environment thermostat
with pump switch off. Contact closed = normal operation. Contact open =
compressor and pump are switched off.
3= Multi-function input enable (ID4) used as Activation of Power Limit
5 through analogue input B1.
4= Multi-function input enable (ID4) used as Activation of Variable Set-
Point through analogue input B1.
5= Analogue input enable B1 as temperature adjustment probe on plant
storage tank.
See parameters from N36 for other multi-function input settings.
300 Time of flow switch bypass during the switch to domestic water.
Room temperature above which the heat pump is disabled. The pump and
compressors are switched off. Hysteresis of 4°.
70.0
If domestic hot water is requested through ID6, the unit is also enabled
with high ambient temperature.
The temperature of the input water above which the pump is switched off
and a pre-alarm is generated. After the pre-alarm comes on, there is a wait-
ing time of 15 minutes before the pump starts up again. After the third
80.0
intervention, the machine goes into alarm/lockout. Active also with the
pump switched off, and the chiller in standby. In the latter case, the alarm
is generated. Below this threshold the pre-alarm is deactivated.
