ARTHUR MARTIN GAIA Serie Manuel D'utilisation page 82

[Notes]
●This function is allowed only when the control panel has just repowered and not turned on. For the main unit
which once has been put into operation, this function is unavailable, alerting "Wrong operation!".
●It will not be memorized upon power failure.
2.4.13 Gate-Ctrl.
[Operation Instructions]
At the commissioning parameter setting page, by touching "Gate-Ctrl.", the control panel will go to the
corresponding setting page.
[Notes]
●When "Gate-Ctrl." has been activated; the display panel will detect the card state. When the card has inserted,
the main unit will run normally. When the card is drawn out, the control panel will turn off the main unit at once and
back to the homepage. In this case, all touching operation become ineffective, and a prompt dialog box will pop up.
The main unit will resume normal operation until the card has inserted back and the ON/OFF status of the control
panel will resume to that before the card is drawn out.
●This setting will be memorized upon power failure.
2.4.14 C/P limit (Current Limit/ Power Limit)
[Operation Instructions]
1. This functions targets for user's electric circuits with poor carrying capacity and unable to let the main unit
operates under full load. When it has been activated, the user is allowed to set the current limit value based on the
carrying capacity of their electric circuits. During operation, when the current exceeds this value, the electric heater
will first stop working and then frequency of the heat pump will be dropped until the current is less than the limit
value. As there is a deviation for the detected current, it can be corrected through "ΔValue min".
2. Current limit function will limit the action of the load, make heating/cooling/water heating slower, make output
capacity much lower, and even limit some functions. Do not activate this function unless necessary. Once it has
been activated, do not set it too low, otherwise the main unit's capacity would be degraded and some functions
would be limited.

There are three options available, "Off", "Current limit" and "Power limit".
Power or current limit
As there is a deviation for the detected current, it can be corrected through "ΔValue
min". When "ΔValue min" goes larger/smaller, it is more likely/hardly to trigger
the current limit function. For example, when the current limit value is 32A, but the
current limit function fails when the actual current exceeds (a clip-style ammeter
can be used for current detection), raise "ΔValue min" as so to trigger the current
limit function more likely.
There are two options available for the electric heater, "With" and "Without",
which determines if the electric heater should be taken into account for current/
power limit. Two power supplies are required, one for the main unit, and the other
for the electric heater. (1) when they are separate, it can be set to "Without". In this
case, current/power limit works only for the heat pump. (2) when they are supplied
together through an air switch, current/power limit works on both the heat pump
and the electric heater.
(1) when a standard auxiliary electric heater is supplied by the manufacturer, the
power is not required to be input but is automatically identified by the main board.
(2) when an auxiliary electric heater is field supplied, the user needs to set "EH
Power 1" and "EH Power 2".
(1) when a water tank with a standard electric heater is supplied by the
manufacturer, the power of the electric heater is not required to be input but is
automatically identified by the main board. (2) when a water tank's electric heater
is field supplied, the user needs to set its power and meanwhile shall make sure
the correctness of the power setting.
