Machine out of coolant differential
If the difference between the absolute value of Al2 and is lower than this parameter when in heating and higher when in
cooling, the machine out of coolant timer will start.
Machine out of coolant bypass
Determines the delay between the turning on of the first compressor in the corresponding cooling circuit and activation of
the machine out of coolant alarm diagnostics. Expressed in minutes.
Machine out of coolant duration
Determines the amount of time beyond which the machine out of coolant alarm will be triggered.
Machine out of coolant alarm activation
Enables machine out of coolant alarm
Enable low pressure alarm during defrosting
Enables the minimum alarm during defrosting. If 0, the low pressure alarm is disabled during defrosting.
Over-temperature set point
Temperature value Al1 above which the over-temperature alarm E46 is triggered.
Over-temperature ON duration
Determines the duratoni of the condition Al1>A25 beyond which alarm E46 is triggered.
Pump parameters (PUP)
Pump operating mode
May be used to determine pump operating mode:
• 0=continuous operation
• 1=operation in response to a request from the regulation algorithm
• 2=cyclic operation
Pump or fan operating mode
May be used to determine pump or fan operating mode:
• 0=(pump) continuous operation | (fan) the fan is never switched off
• 1= (pump) operation in response to a request from regulation algorithm | (fan) the fan is turned off with the
compressor
Delay between pump ON and compressor ON
May be used to set a delay between starting a pump and starting a compressor. Expressed in seconds.
Delay between compressor OFF and pump OFF
May be used to set a delay between turning off a compressor and turning off a pump. Expressed in seconds.
11.1.5 Anti-freeze/boiler parameters (FRO)
Configuration of electrical heaters in defrost mode
Determines electrical heater operation during defrosting
• 0=come on only in response to a request from the regulation algorithm
• 1=always on during defrosting
Configuration of electrical heaters on in cooling mode
Determines electrical heater operation in cooling mode
•
0=off during cooling
• 1=on during cooling (in response to anti-freeze electrical heater regulation algorithm)
Configuration of electrical heaters on in heating mode
Determines electrical heater operation in heating mode
• 0=off during heating
• 1= on during heating (in response to anti-freeze electrical heater regulation algorithm)
Configuration of anti-freeze electrical heater control probe in heating mode
Determines electrical heater control probe in heating mode
• 0= Controls on the basis of probe Al1
• 1= Controls on the basis of probe Al2
Configuration of anti-freeze electrical heater control probe in cooling mode
Determines electrical heater control probe in cooling mode
• 0= Controls on the basis of probe Al1
• 1= Controls on the basis of probe Al2
Configuration of electrical heaters when OFF or on stand-by
Determines the status of electrical heaters when the instrument is OFF or on stand-by
• 0=Always off when OFF or on stand-by
• 1=On when OFF or on stand-by (in response to anti-freeze electrical heater control algorithm)
Set point of anti-freeze electrical heaters in heating mode
Temperature value below which anti-freeze electrical heaters come on in heating mode.
Set point of anti-freeze electrical heaters in cooling mode
Temperature value below which anti-freeze electrical heaters come on in cooling mode.
Maximum set point of anti-freeze electrical heaters
Determines the maximum setting of the anti-freeze electrical heater set point.
Minimum set point of anti-freeze electrical heaters
Determines the minimumsetting of the anti-freeze electrcial heater set points.
Anti-freeze heater hysteresis
Anti-freeze electrical heater control algorithm hysteresis.
Set point of external anti-freeze electrical heaters
Temperature below which external anti-freeze electrical heaters come on.
Outdoor temperature set point
for boiler on
The temperature below which the boiler is turned on and the heat pump is turned off.
