[1] This item shall be masked when not used.
[2] This item is displayed in certain unit configurations only.
[2] Depends on the configuration of the reset type. If reset type is 1, 2 or 4 the unit is °C; if reset type is 3, the unit is mA.
[3 bis] The scale depends on the reset type selected.
[4] Depends on the value of items 9 or 10 of the user configuration menu 1.
If the reset type selection point
= 0: reset not selected
= 1: reset based on outside temperature
= 2: reset based on temperature difference
= 3: reset based on 4-20 mA control
= 4: reset based on room temperature
Reset thresholds in cooling or heating mode
Reset threshold

This item lets you modify Cooling setpoint 1.
This item lets you modify Cooling setpoint 2.
This item lets you modify the ice storage setpoint.
This item lets you modify Heating setpoint 1, only displayed for heat pumps.
This item lets you modify Heating setpoint 2, only displayed for heat pumps.
Automatic changeover threshold, cooling mode. This item lets you display and modify the outdoor temperature
threshold at which the unit changes over in cooling mode. Displayed only if the auto cooling/heating changeover function is
selected.
Automatic changeover threshold, heating mode. This item lets you display and modify the outdoor temperature
threshold at which the unit changes over in heating mode. Displayed only if the auto cooling/heating changeover function is
selected and if the unit is a heat pump. The heating threshold must be 3.8°C below the cooling threshold, otherwise the new
setpoint will be rejected.
For the desuperheater option, this item permits control the minimum condensing temperature setpoint.
This item lets you display and modify the heat reclaim dead band.
Demand limit 1 setpoint. Limitation by volt-free contact. This item is used to define the maximum capacity that the unit is
authorised to use, if the demand limit contact(s) activate limit 1. Contact control depends on the configuration.
Demand limit 2 setpoint. Limitation by volt-free contact. This item is used to define the maximum capacity that the unit is
authorised to use, if the demand limit contact(s) activate limit 2. Contact control depends on the configuration. Displayed
and used only for units with energy management option.
Demand limit 3 setpoint. Limitation by volt-free contact. This item is used to define the maximum capacity that the unit is
authorised to use, if the demand limit contact(s) activate limit 3. Contact control depends on the configuration. Displayed
and used only for units with energy management option.
Cooling ramp loading rate. This parameter is only accessible if the ramp function is validated in the User Configuration 1
menu. This item refers to the maximum permitted water heat exchanger low temperature rates (°C/min). When capacity
loading is effectively limited by the ramp, mode 7 is active.
Heating ramp loading rate. This parameter is only accessible if the ramp function is validated in the User Configuration 1
menu. This item refers to the maximum permitted water heat exchanger high temperature rates (°C/min). When capacity
loading is effectively limited by the ramp, mode 7 is active.
